Which would be the better upgrade: CPU or GPU?

I'm musing the possibility of upgrading part of my system in the next few months.

Basically, I want to achieve better minimum gaming frame rates in the latest games and perhaps have DX11 compatibilty, although that still aren't many games that really use and benefit from it. But I'd still like to have it. :D

My system at the moment (the main bits relevant to this)

E8500 3.16GHz dual core CPU at 4.11GHz
4GB (2 sticks) OCZ Flex 2 PC2-9200 (1150MHz DDR2)
GTX 285
Corsair HX850W PSU
1920x1200 LCD monitor

I would be looking to spend around £300-£400 and I'm wondering if I'd be better off upgrading the CPU to a quad core i7-something, mobo & DDR3 or get a GTX 580. I'd like to get CPU & GPU of course, but that's just too much money to shell out.
 
With that system, I'd honestly go for i5 + GTX570 or HD6950. Going for the best GPU while neglecting the CPU is a no go imho, same for the reverse. Then again, with SandyBridge/Bulldozer so close, this might not be the best time for a full system upgrade

...


screw it, get the GTX580.
 
if you basically only game, GPU... If you do at least a little bit of stuff only CPU intensive... CPU

What motherboard you running? Just curious, I say i5 with an SLI capable motherboard and pickup a 2nd GTX285 while your at it.
 
EP45-UD3P I'm guessing, looking at his System specs :rolleyes:
 
I'd say get a card. Next year I think what, like 3 new sockets are going to hit? You'll have plenty of interesting stuff to choose from. I wouldn't blow a core upgrade on anything out now.
 
Why not AMD 8xxG mobo,4GB DDR3 and Thuban 6 core CPU?

Good suggestion, but I don't see how any games released anytime soon can benefit from that. Probably getting the X4 BE is enough. Hold off purchase till Sandy Bridge and hope for price drops? Yeah, I know VAT is coming up...
 
Thanks everyone. My CPU does still have a lot of horsepower, despite it being a generation behind and a couple of cores behind.

So yeah, I'm glad you're saying the graphics card, because my heart was there. ;)

And n-ster, it is indeed the EP45-UD3P. I didn't list it, because the mobo doesn't make huge odds to the raw performance of a PC nowadays, except for very large overclocks really. I don't count my 1GHz overclock as all that large or special, because I bought this CPU knowing it would do a 1GHz overclock without breaking sweat.

@JR: I avoid going SLI or Crossfire, because it's expensive, tends to have issues with profiles and stuff and consumes a lot of power. But nice thought, adding a second GTX 285 (getting a bit hard to find now) isn't such a silly idea. :)
 
I just got a GTX470 and I freaking love it. I reckon you should get a new GPU.
 
Asus GTX 580 for cheap!

Ok people, so I got the GTX 580 today from Amazon for a mere £311.25! Wasn't intending to buy it right now, but this price is too good to ignore. :D

If you want to get one too, I posted about it here.
 
That was a damn good deal. $450 for a gtx 580 is very good indeed. So the price wars have started! bring it on!
 
I think that, when Sandy Bridge/Bulldozer comes around, you should sell your current parts, save the money you have, and buy completely new parts. My two cents. :toast:

:rockout: Just thought the same also.

Good deal on that 580! If you got the cash get 'em!
 
gpu is always more important good buy.
 
dual core with 3 gig thats kinda enough since most of application today just utilize 2 core, 4 core will help but not all the core will run on high speed
its better you upgrade your VGA
 
Thanks for all the positive feedback people! :toast:

And as far as actually having the cash, it was more a case of "applying the credit card" as the deal was too good to miss... lol :laugh:
 
I reckon you'd be better off with a gtx470 or 480. Running a gtx580 with your cpu & mobo you might be bottle necking the gpu.

Plus how long you going to be waiting for amazon to get them asus gtx580's in stock ? Carn't see it being till 2011 now :ohwell:

Yes, it might bottleneck it some, but this CPU is running at over 4GHz and still has loads of horsepower, and my GTX 285 sometimes does slow down more than I'd like, so a card upgrade seems reasonable. Another way to look at it, is that getting an "overpowered" card allows me to turn up the eye candy without loss of performance ie no dropped frames leading to judders. This is especially important when running DX11 graphics and tessellation.

And finally, I got the top card, because I don't like getting second best... :D

I agree that this sale might be cancelled by Amazon, but hey, it didn't hurt to try.
 
U overate your cpu ! An e8500 @ 4ghz is great for gpu's such as gtx470 or hd5850 but running a gtx580 with a e8500 even at 4ghz is asking a bit much. Its bond to bottle neck the gpu to the point where you'd be getting better frame rates if you had a gtx470 insted.

No, that's where you're wrong. Using a more powerful card will always give you the same or better framerates. You're suggesting that the better card somehow loads the CPU more, but that's not the case.

wait till Jan 11 dude, then we'll have the HD6990 and Sandy Bridge.

I think buying now would be a BAD decision

Yeah, you're right. I haven't upgraded my PC in ages and I've got the buying itch! :laugh:

That comment is totally wrong ! What do you think the term bottlenecking is referring to ?

Putting a higher spec gpu in WILL put more load on the cpu & if your cpu isn't up to the job then you can see lower frame rates with a better gpu.

You need to read up on bottle necking a gpu ;)

Honestly, it doesn't. I've been there with my old Athlon X2 setup, where I found that putting in a more powerful card gave me very similar performance to the older one and certainly no lower. That baby was CPU bottlenecked. You will also not see it explained the way you have, in any graphics card articles.

I think your confusing it with the driver overhead in multi GPU setups, which can indeed lower performance with a weak CPU.
