Celeron, for gaming, really su** a**. A little example: I had a celeron 2.0Ghz overclocked to 2660Mhz (FSB of 533 instead of 400 and with proper cooling) and my score with a radeon 8500 64MB in 3dmark 2000 was something like 5000~5500. Now, I just changed my CPU for a real P4 (2.4a) not oveclocked or anything, and my score went up from my 5000ish to 12 000. And in 3dmark 2k1 it went from 7000 to about 10 000. If you are a gamer, stay away from the Celeron.
