    I didn't mention it's sitting downstairs where the ambient temps are below 25ºC.

    Quick question boys, what's better:

    2x 8800GTS 640mb
    or
    1x GTX260 216sp with AC Accelero GTX280 installed.

    Looking at PPD/Wattage. They're costing about the same :)

    Well, the PPD would be roughly similar on both.

    And I'd estimate that the GTX260 would use a good ~30-35w less

    Those G80 cards are know to be power hogs so the single GTX260 should be similar in PPD if not more (just a little).

    I'd imagine a single GTX260 would take less power than dual 8800GTS. Also, the 260 would have 24 more shaders than the two 8800GTS. The only problem, I can't remember how far you can push the shaders on the 260's compared to the 8800GTS. To see which would produce more PPD, take the number of shaders and multiply by the final clock speed you'll be running the shaders at (I know, common sense but you never know who has it and who doesn't). Most Nvidia cards scale linearly with shaders x clock speed in regards to folding.

    I was looking and found that the 8800GTS 640MB's drew 150w ish, so 300w total compared to the 131w of the GTX260?

    Also, heat as a factor.

    I'd be stunned if an 8800GTS G80 was much over 100w.....

    Wow, really? Anyone know of any facts on this. Need to make a decision tonight :)

    W1zzard didn't do his card only power draw back then. It would take some digging to find an apples to apples comparison. My vote is for the 260, especially if it's a 55nm version. (not all 216's were)

    I would take a 260 over my dual overclocked 8800GS (which are identical to 8800GTS in regards to folding). Mostly because I could fit another card beside it for even more shader goodness.

    Know what, and some might hate me for this, but i'm gunna go the 8800GTS route. It's less hassle on my part and one other reason, looks.

    The GTX260 has a red PCB and the AC Xtreme is the GTX280 version so it's too big and really doesn't match my build. The 8800GTS's will just make it look really beefy, lol. And you have to remember this is in my desk. So, it's always in my eye line :)

    Thanks for the comments guys. Reassured me about the consumption of these 8800GTS's. Thought they were going to be 300w+! lol.

    Took a big hit in points!!!!!!!! @ my house they had elect. problems all day for several blocks around me.:shadedshu @ work they had to turn power off to upgrade the transformer so I only had one rig running for most of the day.:shadedshu Good thing is they finally got elect. back on to everything and all of the rigs are back to folding again.:D

    To give us a more stable elect. @ work we are adding more servers and we needed more power to feed all of them plus now we have battery backup and two generator's to feed everything in case of a power loss.

    Upgrades upgrades....:roll:

    More work and less pay now...:eek:

    Theres alot of these 6800 wu's. I turned advmethods off and got a few others and now back to these for some time now. Can't wait till they run out. They take a while to complete.

    Sorry, but I think they're the future. Stanford stated that the low end cards would have problems with them, so hopefully there's a future plan to match the cards and the WU's.

    So what's the point value of these WUs?

    Cool, thanks :)

    And what's the PPD compared to other WUs?

    Just wait until Project 6811 (7202pts) becomes standard fair. Right now that possibility is having me second guess picking up a GTS 450 to replace my GTS 250 :mad:

    Why are you second-guessing it?

    I must say I really don't like large GPU WUs, IMO the best part of GPU folding is fast turnaround times :ohwell:

    When turning off -advmethods no longer can fend off the 6811's (will happen sooner or later) we all have to lower our OC on the Fermis and the lower end cards (450 and down) will be a bad choice. They are too slow on the high atom count WU´s. Stay with the 250 and GPU2.

    That's probably the best move for now.

    Im going to have to readjust my fan profiles again. F. If anyone sees a deal on a Raven RV02, PM me. I need a larger case to put my Accelero Xtreme to a use other than a good looking paper weight.

    IMHO, buying anything less than the GTX460 for folding does not look like a good idea, at this time.

    If/when you get the RV02, please give us a report and pics. I, for one, would like to know if it works as well as the reviews have said. It was on sale a few months back, but it was still around $150.
