I do appreciate you trying to look for alternatives, but the main purpose is to built a powerful machine that woken become old and dated in a short time. I'd rather spend a bit more and make it worth while.
I was originally going for 680 but in scaling back. In a short answer, yes I would like ability to SLI in future.
Any issues with compatability with the parts? Going to order later today probably
Ordered - Had to also buy a 2TB HDD and Windows 7 copy which didnt help the cost =\
