ok, i've decided to go with the intel 850 chipset, i was leaning towards the ASUS P4T533 or P4T533 C. does anyone have any other mobo's they r familiar with which use this chipset that they would suggest over the ASUS boards. it seems that the rd4200 ram seems to be better than the rd1066 seeing that it doesn't have to be installed in pairs. is this the case or is there other issues i should be taking into account. thnx, tom
