To play GTA IV like water (and future GTAs), I am planning to buy AMD Phenom-II, X6 with Gigabyte board. I hv a NVIDIA 9400 GT , 1 GB card. I hope this should be sufficient enough. with 4 GB DDR3 and 1 TB HDD.
However is it possible to get a new Graphic card say another 1 GB and make it to work with the existing one making my Video memory to be double? If this requires some special board then pl let me know as I hv not bought yet, I am planning to buy gig - MA785GMT.
