Hey guys im struggling on which card to go for im sure ill go for a GTX 570 unless this new 660 is around the same price etc? im unsure here. Basically the 2.5gb version is only £20 more than the 1.28gb version

1280MB EVGA GTX 570 HD SuperClocked, 40nm, 3900MHz GDDR5, GPU 797MHz, Shader 1594MHz, 480 Cores

2.5GB EVGA GTX 570 HD, 40nm, 3800MHz GDDR5, GPU 732MHz, Shader 1464MHz, 480 Cores, 2x DVI/ DP/ HDMI

Theres the specs for both. Im unsure which one to go for.. also if you can point a better card for around £220 ill take that into account :) .

Oh sorry PC specs atm:

GPU : none

MOBO -Asrock Z77 Extreme 4

PSU - Corsair GS800

RAM - 8gb ddr3 vengeance

CPu - i5 2500k (with H80)

HDD - Western Digital Caviar Black 1TB Hard Drive 7200 RPM, 64mb

The extra VRAM will help at high resolutions with games like Max Payne 3 but the faster core speed on the lower VRAM one is also a benefit in performance.

Personally I would go for the higher VRAM model mainly for longevity as games will start using more VRAM as resolution continues to go up.

hey,

what games and on what resolutions do you play on? For only 20 pounds more I would say that the 2.5gb version is better as it is more future proof as @jimmysmitty said, because games are starting to consume more and more vram. If you play at higher resolutions, and depending on what games you play than the additional memory will be helpful.

Hope this helps!

The higher ram one is better. Plus you could probably just overclock the 2gb one. The higher ram one will allow you to play games on higher settings. There is also the factor of price and I'm assuming that the 2.5gb is more expensive.

Mainly, the extra VRAM is needed for larger resolution monitors or muli-monitors. The amount of eye candy you want to use also determines the amount of VRAM you may want.
I haven't experienced any need yet for more than the 1.28GB of my 2 GTX 570s @ 1920x1080. But if you were ever to go to 3 monitors, you would need more.

To be honest if you can pay the extra 20 pounds then go for it, it will be more future proof, and if you play @2560x1600 or if you use multi monitor set ups you will have a benefit of the extra vram. If you don't do that then you still will see some increase in vram hungry games. The worst case scenario is that in some cases it decreases your performance by 1-2fps but thats no biggie, in most cases it will definitely increase your performance, and if you can then go for it.

At 1600x900 Max Payne 3 with everything maxed ot and 8x MSAA uses 1.6GB of my HD7970s 3GB. I would assume 1920x1080 would up it to near 2GB.

Thats just an example. Most games will stay around 1-1.5GB for the most part unless its like Skyrim which has HD texture packs and even some user created texture packs that are even more HD (like 4K textures).

I still say 2.5GB one is worth the extra $20.

Yup, 2037 MB of VRAM, and you still need to change that monitor to at least 1200p one :p 

Thanks very much guys im going to go with the 2.5gb version and overclock it hopefully :) . One day ill be using a multi monitor display so its wise to go for this GPU. Thanks again i feel confident in getting the more vram version now !

I haven't gotten Max Payne 3 yet, but I have read that it is a very graphically demanding game.
Btw, is the single player game any good?
