Edit: Made a mistake in title, it's the 2600, not 6600. My personal review. 3/10 This video card was a disaster. To start things off, the video card would not take the drivers from the CD, itself. Had to locate these drivers off of the Manufacturer's website (which was not ATI, it was some other brand. I took this card back, so I don't remember). After going through the process of locating the drivers, I had to reboot, normal right? Well unfortunately, all of my BIOS, and checksums were pixelated. After getting back into Windows Vista (yes, the card did say Windows-Vista Compatible), everything was fine (except now Windows was having a rundll error, always fun). Watching movies, I did actually see a performance increase. Amazing quality. When it came to games, is the part that really made me go crazy. Games Tested: Battlefield 2, Battlefield 2142, Counter-Strike: Source, Gary's Mod 10, Zombie Rising (HL2 MOD), Portal, Air Rivals, Jedi Outcast 2, Dark Age of Camelot - Catacombs / Labyrinth, and World of Warcraft. ALL of these games would send both monitors black, and freeze the system withing 10 minutes of playing. I actually tested Counter-Strike: Source first, and the first time this happened, within the first minute of my black-out, the system recovered. It just closed my game, and that was that. It only recovered once. After about a day of this non-sense, I returned the card, because ATI was just giving me generic solutions via phone and email, and the ATI Out-sourced Manufacturer of the card I had purchased's forums were saying there was no fix for this (XP, or Vista), I gave up. If you're looking for a 512MB AGP Video Card, go nVidia. nVidia GeForce 7300 GT > ATI Radeon HD 2600 XT Thanks for reading!
