Couple of Comments:
1) I would look to get a HSF, so you can overclock that CPU!! The Sunbeam CCTF is a good cooler for the price.
2) Your motherboard isn't designed for a Crossfire setup, so you can drop down to the 550W version, if a combo is still there.
I might overclock later on, but if I don't overclock for a couple months, will the stock HSF be alright?
Also what Motherboard would you recommend if I wanted to throw in another videocard later and Crossfire them? Might be handy down the road instead of upgrading one videocard, just tossing in another one.
