Guys, I have not suggested the Biostar TA790GX M/B jsut for performance, I suggested it for a future proof solution.
None of the 780G chipset based boards support Phenom II processors naively. It requires a Bios update (Even if if u r not doing it, The company has done it for u). They don't support some advance features of Phenom 2 Processors, like Advance Clock Calibration(ACC), unlocking the 4th core of a X3 processors, etc.
Biostar M/B offers it all. It supports high overclocking (My Phenom 2 940 is overclocked 3.6 GHz), has lot of expantion ports, support CF, having 128MB 3300 Graphics and price is just 5k. I think its the best buy and the extra 1k u r soending, is highly justified.
