I was going to buy this card it is cheap off ebay and my only concern I want to be able to run call of duty 4. Asus nVidia GeForce 7300GS 128MB HDTV/DVI PCI-Express V I know I wont be able to max out the settings but will it run on low graphics.
If you're going for a low end card, i'd suggest maybe a 7600GT, they're still quite cheap and far batter than a 7300GS. I used to have a 7300LE in my old PC and it did run Call of Duty 4 fine, though yes, on lowish settings, it's worth getting a bit of a better card though, you'll probably manage medium on a 7600.
it is really worth saving up for a better video card because you will regret it if you want to play a more demanding game than cod4 and cant and you have to buy another one... if you will save up then defiently check out the nvidea 8 series!
