kinda hard to choose. I mean that ram is expensive but can run faster. I Would still got with a new mobo,cpu and case combo. But to get good stuff you will be spending more than you would in upgrades. But you will be gaining alot of know how and that would save you lots in the future. But that p4 with rambus is a good system because of the ram. Motherboards that i have had no problems witha are soyo. Ive had problems with ASUS, ABIT, and gigabyte. I currently have a gigabyte and i am very dissatisfied. I loved my abit but i fried it. so i decided to get a gigabyte and it sucks.
