I have a Dell Optiplex (Small tower) GX620 3.0GHz (pentium 4) dual core, 32bit operating system, and 2gb ram... I bought GTA4 and went to BestBuy to get a graphics card for it.. I learned that I needed a Low Profile card and the salesman told me to get the NVIDIA GeForce 210 so trusting him I did... Well, now i know that this card IS NOT powerful enough to play GTA4 because its so choppy I just uninstalled it... What can anyone reccomend for getting my GTA4 running good enought to enjoy playing? I plan on changing the vehicles and such so I dont know if that means it will need a really top notch graphics card or not? Any help? First post.
