If you're not going 1440p,2GB will be enuf ATM..tryout the new Zotac GTX770 AMP! Edition laa..

Actually, your hypothesis is not fully accurate. It is true that some of the newer games e.g Crysis 3 consume more than 2GB memory at even 1080p according to this review by Guru3D, but this alone will not be the reason why the game isn't playable. Even with a 4GB VRAM, the GPU itself isn't strong enough for you to even play smoothly with all the details maxed out. So we shouldn't conclude that 4GB will simply allow you to play most games at 1080p lag free, when some games are so intensive that the GPU will simply run out of processing power, rather than become memory limited.

Even HardOCP concluded that there isn't any advantage between a 2GB and 4GB version of the GTX 670.

That too, but a 4Gb card will open up possibilities for future SLI. Wouldn't be much point doing an SLI setup if you're going to run up to a VRAM wall when using 2Gb cards.

We've given the ASUS GeForce GTX 670 DirectCU II 4GB video cards plenty of opportunities to prove to us why we would need 4GB of VRAM on these. Unfortunately, these have come short of proving this. We tried pushing a single ASUS GTX 670 4GB to the max on a 30" display, at more than playable settings, and also at 1080p. We saw no advantages with a single card. Then we put two together in SLI and tried to push them to the max at 5760x1200. What we found was that higher settings were possible to enable, but the performance wasn't there to allow them to be playable. Simply, the performance of GTX 670 isn't enough to utilize the capacity of 4GB of VRAM.

Same scenario is replicated as well, as reviewed by HardOCP. You'll likely run out of GPU processing power before hitting the VRAM wall.

True we might never see a game which utilizes the full 4Gb anytime soon, but newer ones like Metro LL and Crysis at Ultra-Max settings have already gone beyond 2Gb VRAM. I wouldn't say it's cost effective seeing as we barely get any games which utilize it, but it does come in handy in the few games that do, and the number will only increase with newer games coming out.

so i guess 2gb would be the best choice i supposed..however what do you all think bout the power supply? good enough? need any cooling system or anything else to add on?

if i were to do SLi in the future, can my mobo support this card? looks huge and gigantic

yeah but the for the moment shall just stick with 1 card

just wanna ask if you are stressing the GPU would it be very noisy?

as im experiencing now, for example if im playing guild wars 2 my pc would be kinda noisy

i see thanks for the advice guys

looking onto zotac's 770 i wonder why isit so cheap and one of the guy selling asus 770 for only 1420? i wonder why

yeah but why isit much cheaper than others?
