Lets say i had an infinitely powerful CPU, RAM, PSU etc. and a GTX 560 Ti 1GB; would the lack of more than 1GB have an effect on performance? i commonly hear people on youtube say that it is one of the few games that actually NEEDS more than a gig to be fully maxed out including view distance at respectable frame-rates.
I'm getting a GTX 560 Ti 1GB. i will overclock it heavily (hopefully to 1GHz +) , but that doesn't change the amount of VRAM.
should i get 6950 2gb instead for roughly the same price? or is even GTX 570 or 580 necessary? i don't really want to spend more than $300 on a card, but i will if it can max out this games and possible sequels
GTA IV needs a quad core atleast to run smooth, i could get my ole 8800GT 512mb to run it on medium "smooth" but the biggest difference was because i overclocked my Q6600 from 2.4ghz to 3.5ghz (made the most difference)
