I do remember hard issues with WinNT 3.51 and original Win'95 when running on Cyrix 5x86\6x86 or NexGen Nx586. I agree there were some bugs in return stack and branch prediction of Cx5x86, but Intel CPUs are not bug-free, and every chip still comes supplied with a pretty errata list. Another question is quality of Microsoft OS'es and their VC++ compiler. They are still far from perfect, like 7 years ago... --- Regards, Rhett __________________________________________________ Do you Yahoo!? Yahoo! Mail Plus - Powerful. Affordable.
