then just add in an OS i recommend Win7 Professional x64 OEM
you can always add another Graphics card too depending on your budget i would say add another 5770.

Generally I would recommend gigabyte or asus, however with what's left of the ddr2 am2/am2+ socket motherboards I would say this is the best possible one available. Also, I would invest in a single gpu instead of crossfire, it uses more power, generates more heat, and isn't as efficient as a stronger single gpu. Also, I can't find the info on what the bandwith of the two PCI-e slots.
Hope this helps with your decision making!
