Hi. I just got a new graphics card (Ge-Force FX 5500 PCI 256MB) today. I couldn't wait to download F.E.A.R and Doom III demos. I waited, until they were done. Finally, I installed them, restarted my computer, and played F.E.A.R first. I put it on the highest setting possible. It ran amazing!!! The same with Doom III! I have waited so long to get a cheap, good graphics card... I reccomend you get the Ge-Force FX 5500 PCI 256MB. ITS THE BEST!
Buy it at Best Buy for only $100! SUPER CHEAP!

If you have any problems, just post in this (Doom 3 Reccomended) forum. If it is good, post and tell me how good it is...
