Looks awesome. though i would say spend a little more cash on a better psu... this is probably the best bang for the buck psu ive seen around although i have really checked many out so you may want to do some more shopping around. as for the motherboard, ive always heard good things about them, one of my buddies swears by them so i wouldnt worry about that. also look into getting a nice cpu cooler, you got the black edition phenom with the unlocked multiplier... you might as well overclock it
This Build offers very nice customization parts like a full modular PSU and a Case which is ready for water cooling and has a nice side window, But if you still want to go with AMD for OC capability then just say it and I can reconfigure it to be a price/performance AMD Rock machine! aldo the intel i3 is about the same as a 955 BE.
Also this Build is ready for Ivy Bridge which is Intel's next CPU upgrade and supports PCIe 3.0.
