The prices were about the same, but the Athlon was at least twice as fast for chess using Fritz and Shredder as benchmarks. It could be (?) that Shredder loses some strength (relative to Fritz etc) on the slower Celeron, but I'm not sure. I believe this difference continues with current processors, in other words AMD is better for chess than Intel when comparing processors of similar prices. If I were to get a new computer now it would be one of the AMD 64 processor models, an X2 dual core if I could afford it. I believe that requires Windows XP Pro (rather than Home) to get a compatible 64-bit OS. However I'm still pretty happy with my Athlon XP 2400+ so may wait a couple more years before upgrading, partly because hard drives are getting bigger and I will want enough hd memory to hold the 6-man tablebases on my next machine.
