I was thinking of a cheap PC with a decent video card. What would you recomment as video card and hardware, how a bout a ASUS GF 7300GS, would that be enough or I would have to go for a 7950 GT ?
If you're not playing games that demand little power in terms of graphics, look at the ABit F-190HD. It has HDMI built-in and features the ATi Xpress 1200 chipset all in a microATX form factor. Quite expensive though.
