that's a good board. I used that board in my wifes build. it currently has my old 4 core FX4130 in it and it performs pretty good, even using just the on board video. It would probably clip along pretty good if i plopped a videocard in it, but she mostly plays facebook games on it.

it has 4 ram slots so if you decide to go with the 2x 2gb you can easily pop in another 2 no problem. i would probably stick with standard 1333 memory (what the board is rated for)... you aren't going to benefit from 1600 ram unless you overclock and push up your memory speeds. I generally stick with plain old kingston value ram. it's got a lifetime warranty. never had a problem with it.

well...the 4 hard drives, half dozen fans and water pump don't help either
