I have been looking to up grade my video card. I have a 500 watt PSU and one AGP x8 port, and I am hoping to find a good video card in the $200-$250 range. Some of the games it needs to run (with highest settings if possible) are Doom 3, Half-Life 2, Quake 4, Pariah, and Halo PC. Now, I have done some research, reading reviews and looking at the Toms Hardware AGP Charts. In the end, I came to think that the PNY GeForce 6600 GT might be a good deal for the price. However, after reading posts on this forum about it, I found many people saying that it's not a good video card and that there are better ones for the same price. The second one I am looking at is the GeForce 7800GS OC . Any input on that one? Could I get a few suggestions for decent cards in this price range? Thanks a bunch.
