Re: Help with upgrading my system
I would spend a little more on the mobo, say "ASUS M4A785TD-M EVO AM3 AMD 785G HDMI Micro ATX AMD Motherboard" this gets you USB3, HDMI, supports faster ram, and the onboard video is a good back up.
Going from DDR to DDR3, its going to be faster. thou if your running a 32bit windows your only going to see 3.1 to 3.2GB of ram
As for the cpu, I have the PhenomII X4 965 Black 3.4GHz. and it sits idle at 34c and 47c while gaming with a stock fan.
So don't spend too much on cooling. unless your planing on overclocking it.
