Not extactly. AMD has to make is confusing. Well, there is a 2700+ with a 333 FSB. Then there is a 2600+ with a 333 FSB, and a 2600+ with a 266 FSB. Whatever you do, get one with the 333 FSB. They perform a lot better. Just make sure you get memory that is DDR 333. Corsair makes the best memory. I got Corsair DDR 400 2 X 256 MB sticks, with no problems. So, good luck.
