If you want to use a AM2+ processor like the 940 with DDR2 memory. If your just going to use a Nvidia card and not crossfire.
Dont get the GA MA770 UD3, the power setup sucks for a X4 940
Best deal with a 8+1 power phase setup.

If your getting a ATI card and might Crossfire later.
The best bang for your buck. 8+2 power phase
setup
