Wow, thanks Awdax, I've got an AMD 6770 and a Phenom quad core and I had pretty bad FPS even on lowest - this will probably at least let me run it on medium well. Thanks.
Also I'm not up-to-date on this stuff, is GTA V getting a PC port?
They probably will, they always have. Before someone brings up the whole Red Dead Redemption thing - the game's code was a horrible mess, on top of that it was a completely different branch from Rockstar - San Diego. Rockstar has always ported their GTA games, why should they stop now?
Or you could wait and buy it on the PC. It's not like EVERY OTHER GAME in the series was on the PC.
I'd rather get it on a console instead of having to wait six months or longer to play it and not have it spoiled, then just buy it again on the PC when it's on sale or something.
