I just ordered a turnkey video system from Polywell computers - a dual Athlon system using the Matrox RTX100 and the Parhelia graphics card. The engineer says he can't get the RTX100 to run reliably under XP and suggests installing Win2K instead. Are others having problems with the RTX100 and XP? Is Win2K a viable option or should I stick with XP and find another computer manufacturer? Advice welcome.
