LF solid Gigabyte board

[SaintKr0]

CPU : AMD Phenom II X4 955 Processor
MB : Asus M4A79XTD EVO
GPU : Radeon HD 6870
RAM : 4096 MB DDR3 Single Channel
HD : 2TB
PSU : 500w

I want to replace the MB with something a little better in the Gigabyte family. Any suggestions?

any thoughts on this: Gigabyte GA-990FXA-UD5, with my current setup? overkill, nice room for upgrading, etc?
