    GDDR5 was supposed to consume less at the same clocks and currently GDDR3 speeds are higher than GDDR5 speeds, GDDR5 being in the 800-1000 realm (not OC) and GDDR3 being in the 900-1100 area (again not OC). At least that's how it was marketed and I think that was true.

    I like the performance per dollar chart, a lot.

    I didn't say that was the only reason, but if I didn't had the oportunity to get the 8800GT that cheap, I don't know what I would have done in the end. But that is a completely different thing, we are talking about a 15w difference in a card that is 20% faster (actually 30% on their max OC), which is far from 95w and a 9% difference in the case of GTX295 vs 4890 CF (two fastest things in Wizzard's charts, they cost the same BTW). OC ability doen0t matter as the GTX295 OC wonderfully. Watercooling or aftermarket cooling? If you are going to spend more, you might as well want to spend a little more and get GTX285 SLI.

    Buying a second rig won't save any money, you pay for the extra hardware.

    Your point isn't good anyway. If money doesn't matter, that people wouldn't be considering the HD4890, they would simply go for the Quad CF with X2, the Quad GTX295 or Tri SLI with GTX285.

    I don't care too much about what people do, because I'm just trying to help those inconscious (in the sense that they never thought about this) people, trying to teach them something indeed. They should learn to manage their money and think about these things. You say it only matters the money at hand (entry cost) at the time of the purchase, well with a less consuming setup you'll get that money much earlier. It's hypocritical to say you can wait until you have $500 but you can't wait until you have $600, when at the same time you are spending much less in that timeframe. Look at the extreme example I put above, in Denmark (Italy, Netherlands) after 1 year of use the HD4890 CF can cost 132 euros more than the HD4870 X2, 161 € more than the GTX295 and 107 € more than GTX285 SLI. (Tri SLI'ing the GTX285 will consume a bit less than HD3890 CF in idle!!)(Notice how the numbers for the single GTX285 are the same as in Wizzard's review) For average Europe results, slash those numbers in half, they are still significative enough to the point of making GTX275/GTX285 SLI more appealing.

    Again, using a different PC for web browsing, videos and all that won't save any money because the PC itself costs money. You only really save money if you buy something instead of another thing, not if you buy something on top of the other thing. I doubt any enthusiast will have a PC older than 2-3 years anyway, even if it is for watching videos.

    The bottom line is that you can't talk about money arbitrarily. Either you care or either you don't. And with the current situation in the GPU arena, if you don't care you'd go GTX285 SLI (the least) because it's simply faster and if you do care, you should go for a setup that won't cost you more over the time, at least if you are conscious of how much it will cost you. Now that I have demostrated how much it can cost I hope that people in the EU take that into consideration, as it would be the smarter choice and also people in California or New York where the energy is expensive, for example.

    Examples:

    - Right now, if you want to break records you won't get HD4890 CF, you'll get GTX285 Tri or Quad CF/SLI or GTX285 SLI at least.

    - If you just want one of the fastest things you can buy HD4890 CF or just buy the 9% slower GTX295 for the same price and one year later instead of buying another $500 card(s), buy a $600 card because you could save $100 more in bills or instead of waiting one year buy in just 9 months, because you already saved the $500 in that time.

    That's what a smart money conscious person would do. Again, if you have money to burn this doesn't apply to you, do with it whatever you want and know that I would do the same and that I'm jealous.

    EDIT: OH! And BTW, it just takes Ati fixing the problem with power management not working in Crossfire to make all my points null (practical not theorical, the examples, the cards) and me happy because something done well. Even if Ati fans (a lot here) are unable to see it, I have not a problem with Ati at all, neither I have a problem with the HD4890, except for the fact that GTX275 is a bit better. The only problem here is 308w at idle, fix that, end of problem. :)

    I understand the point you are making, and have been understanding it. I'm just telling you that the people I know that are looking to spend this kind of money on a graphics card setup do not care that much about power consumption, so it doesn't really play into their decision. It's on the bottom of the list in importance.

    And I'm not just defending ATI, nor am I an ATI fanboy. If my board did SLI, I'd have 2 280's or 285's. I'm just pointing out that your observations on power consumptions are most likely going to fall on deaf ears at this price and performance level.

    Hey guys, just joined the forum as I'm planning on making a build log for my new i7 build next month.

    Just want to say, I've read through this whole forum and spending 20 dollars per year on 600 dollars worth of graphics cards is a cost easily incurred...

    Spending 3.5% of the price of your cards per year is totally insignificant. If 20 dollars is such a major concern I would highly recommend a) leaving this page, or b) closing your account, because this is a performance PC enthusiast website.

    That's like saying you shouldn't buy a Ferrari because it doesn't get the same mileage as a Kia rondo



    4890....looks excellent but I'll probably wait for the RV870. I know I'd regret buying it when the 870 comes out with 1600 SPU's

    You clearly didn't read te thread. It's not 20$, unless you only use your cmputer 2 hours a day, in which case I find it hard to believe you are an exthusiast. We're talking about anything from 50$ (in very few places) to $200 per year.

    Also which card is the Kia? The GTX295, the HD4870 X2 or GTX285/275 SLI? Man I didn't knew the small Kia cars were almost as fast as Ferraris or even faster. I'll consider Kia for my next car...:eek:

    This is what I was referring to.

    Also i really wish Kia's were that fast....although with some modding, who knows :roll:

    God dammit these benchmarks are full of it. They have no consistency to any other benchmarks I've seen on paper or gameplay I've experienced. Just look at the left4dead benchmark. Broken is an understatement. Yeah, a gts250 would really beat a 4890 and 285. I've played left4dead on maximum settings on my 4870x2 (16xAA & 16xAF @ 1920x1200), and it runs constantly well over 160fps, and rightfully so (since the source engine does favor ATI cards:p). On my previous card, a 512Mb 4870, Call of Duty 4 ran @ an average of 95 to 125 fps (mostly maxing out @ 125fps), in multiplayer, even higher in single player (4xAA, 16AF 1920x1200). Sorry W1zzard, but either your hardware is completely screwed beyond anything I've seen before, or you're biased to the extreme.

    Power comsuption doesn't cost me, it's included in my rent. I even run two air conditioners in the summertime, again, included in the rent.

    Wattage is the bomb when it's included in your rent...I recommend renting!!! :rockout:

    we're using our own timedemos, if you are interested i can mail them to you or you can get them via the tpubench plugins. l4d clearly has a bug where every gpu it doesn't "know" get a performance boost

    Nice try to make a joke. Big FAIL! The short answer would be: yes! The long one is: fluorescent, energy saving ones, LED ones, adjustable switches... I would suggest you think before you even try to make fun of someone next time. Try harder, seriously, you can.

    Trolling? Ha! Maybe if mods respond in the way they should instead of attacking members, people could start respecting the rules better. If talking about power consumption is trolling and off topic, please don't include power consumption tests. Sorry Wizzard, but you should control your dogs tighter. Now you can ban me forever, I don't care anymore about a site with such moderators. Good bye to all the good people in TPU, I enjoyed talking with all of you.

    Buddy of mine just got a 4890 this morning. Sick card, but it is LOUD. Somewhere around 50 dbA at load :twitch: Not a big deal if you plan to liquid cool but thats a noise most people will find aggravating for sure. Any ideas on when the 58xx cards will be out?

    im planning on getting 2 4890s when sapphire releases the vapour x cooler on the 4890. hopefully with some voltage tweaks, so i can tune over 1000mhz.

    Righto, but in relation to competing current gen gpus (ie 4870x2 and GTX295), if one is recognized they both should be. That's why I think there's something seriously wrong with your left4dead benchmark and Cod4 test. The X2 in reality out performs the 295 in that game, as it does in CoD4. The biggest shock however is the 4870 getting only 75 fps in CoD4. But anyway, you probably shouldn't use those timedemos or benchmark apps, since they are obviously flawed. I'd recommend running the actual games performing specific tasks (ie in CoD4 running through smoke, avg running through a heavily populated map etc and recording the results). HardOCD does this, which is why it appears to give far more believable results. Anyway, no hard feelings. Just use a different method in future, and you'll find you get far more legitimate readings. For the time being however, I'll check out the site you recommended. Good luck with your future tests.

    ya the one that is on the 4870 Entices me to pick one up but i think the 4890 maybe my choice when the 2GB edition hits shelves.

    2GB of RAM on a single 256 bit bus? That's stretching it a bit methinks:p Also, it probably wouldn't be used.

    its funny people said that about the 1950 512s ram not being utilized now it is. Goin from a 9700 Pro to a X1950 Pro, the ram Quadrupled. Now im Goin from a 512MB to a 2GB Card, ram quadrupled again.
