Okay, so everyone is posting about their new computers. I just built one yesterday and installed all my programs on it today. Here goes:
Foxconn Renaissance LGA 1366 Motherboard
Intel Core i7 920 Nehalem 2.66GHz Quad Core Processor
12 GB DDR3 Memory
1 TB Hard Drive
MSI GeForce 9600 GT 512 MB Video Card (from my previous machine)
Running Windows 7 64-Bit.
I ran a memory test on the system overnight before installing Windows. It made 9 passes and had 0 errors.
Another blessing is that it turned on the very first time I pushed the power button. No guessing games! 
Oh, and this thing is really fast!
