Qxd6+ Kxd6 21. Rd1 Bg4 22. > f3 Bd7 I think this is because of the BIOS-Settings. These setings have an significant impact to the speed. I don't think, that WinXP consumes more CPU_ressources than W2K (the memory-allocation should be even better in XP). Probably it's the CAS-LAtency which matters. Maybe there were other factors like Antivirus-program in background. A good comparison is Fritz-Mark, but therefor one needs this program. I have only little experiences, but the difference between SDRAM and DDRAM seems quite small for chess. it's probably the CAS-Latency of 2 which matters.
