You're right. The AM3 in the description threw me off. It's usually listed as AM3/AM2+/AM2. Here's Newegg's description of the same board "GIGABYTE GA-MA790X-UD4P AM3/AM2+/AM2 AMD 790X ATX AMD Motherboard - Retail". Yes, the Phenom II X4 940 and DDR2 RAM will work with that motherboard. Sorry for the confusion.
