I'm putting together a system myself and I've just placed the order for the parts from newegg. Wondering what the general consensus is on the parts I ordered:

Antec Nine Hundred Case
AMD 9950 Black 125W
MSI K9A2 Platinum Motherboard
Some heatsink I can't remember... Cooler Master or Arctic?

My old desktop has 4GB of 800 DDR2 and I'd like to update, however I'm curious as to what kind of difference it would make to upgrade to 1066 which the K9A2 supports. Anyone have any suggestions? Appreciate it!
