The 2600 PRO is one of those cards that receives very little press, but when you stop and have a hard look at it, you might see a diamond in the rough. While we were watching the prices of high-end cards, 2600 PRO prices dropped as low as $70 at online retailers. For that low price, you're essentially getting an underclocked 2600 XT, a solid baseline gaming card. If you do light gaming, or you can't afford any better, the 2600 PRO is a good choice.
This card's biggest competitor would be the better-performing 7600 GT. The 7600 GT is a good buy at the $90 price point, but that's so close to the $100 Radeon 2600 XT and Geforce 8600 GT that I find it difficult to recommend over the newer cards, which offer excellent HD video acceleration.
