I have ati radeon 4650 1gb ddr2 128 bit and these two games run on high resolution.
Main parts of my computer is standard - intel e6300, ram 4gb ddr2 800mhz, gpu 4650, hdd 500gb, midi tower with 500 watt and windows 7 64 bit ultimate.
4650 is a lower class video card. Now I looking to buy somethig with minimum 1gb ddr3 256 bit. Once again, even is a lower class, everything run like hell ........
