I've been reading reviews for the 2GB GTX 770 (Gigabyte), and one said users with bigger screens may want to invest in the 4GB.
Anyone with experience of this?
Should I invest in the 4GB for later progression to 1440 \ 27" Screen?
Thanks
Size of the screen is irrelevant, its all about the pixels, and then the game, and then the card you plan to use and in that order, regardless of grunt, some games at 1440P require more than 2gig of Vram but not all, but at 1440P then some settings you can turn down imo without compromising IQ, but each to there own on that score, im happy playing on medium and upwards as im as its all about game play for me and high FPS and as high as refresh rate i can get for better smoother game play and low to zero input lag
General rule of thumb is simple get the best gpu you can afford, and more Vram is better to have and to not need than to need and not have, but myself well im happy to compromise to suit my budget and my needs
A 4gig 770 is false economy as it wont have the grunt to make good use of the extra Vram, however two in SLI would change that as you will have both grunt and Vram headroom, the opposite would be true of two 770 2gig cards tho this would still have the grunt, it would hit the Vram wall @ 1440P maxed out in games like Crysis 3, Farcry 3, BF4 just to name a few
So for me, i would rather have two of the cheapest 770 (seen these for £215) and turn down a few settings to stay under the 2GB limit and play at 120Hz with 120FPS and little or zero input lag or just one card if you have a 60Hz screen
Edit: The R290 would be better value for your money than a 4GB 770 providing that the 14.2 drivers are way better than the 14.1 were, i could not get my R290 to work with them so it went back
