I have 2 Mobile XP2500+'s, one does 2.6GHz, one does 2.4GHz. I honestly don't feel they compare well to an A64, even in gaming. No doubt they were very good buys for the money, but I'd still think the A64 3000+ > AXP @ 2.6GHz. At 2.2GHz (XP3200+) the XP's aren't any better off than a 2.8C Pentium 4. SO I'd say at 2.4GHz, maybe on average it's about a P4 3.0C or A64 2800+ for games. Of course that will all vary by aplication, but I was thinking games as a whole. But at half the cost or less, that isn't too shabby at all.
I'd like to see how a AXP @2.4GHz, A64 3000+, and P4 3.2GHz and a A64 3800+ would compare on a GF6800U or X800XT. Just how bad would each CPU hold those cards back in some games. And which of the 3 CPU's would do the best.
