Well, mine is a culmination of extra parts :

We are pretty picky about what we put in the systems, and when we try out a new board
if it doesn't pass our inspection, or if we feel it is quirky we won't use them.
I was prodded to buy a EVGA 680i Mainboard by some of my employees, and my hubby (BigBadToe350) didn't like it one bit.
So, I ended up with it. It had some issues, and we RMA'd it twice. I think it still is questionable, but it works for me.
I have:
EVGA nForce 680i SLI
Intel E8400 3.0Ghz CPU
XFX NVIDIA GeForce 9800 GT 512mb
4Gb Kingston HyperX DDR2 800Mhz
150GB WD Raptor 10000RPM Hard Drive
500GB WD Hard Drive
Logitec G11 Keyboard
Logitec G5 Mouse
ViewSonic XV2240w 22" LCD
Don't see the benefit of SLI.. been there, didn't like it
and went with just one card.
