if you go with the i7 920 be sure you have triple channel ram, and 8gb is not a valid set, you would want 3gb or 6gb or 12gb:

What do you mean by not "valid"? My computer has the i7 920, and I have 8 GB of ram. It seems valid enough, and runs FSX quite well, but is certainly not the fastest "rig" out there.
yes you can have 8 or 4 etc, but you want true tri-channel setup with the x58 motherboards, thats why if going with ddr3 you want 3 stick of ram
In a meeting between Legit Reviews and Intel it was discovered that three slots should be used if you want the best performance. If you pop in a fourth module and occupy all the slots the DX58SO motherboard won't be running in quad-channel. It will actually default back down to single channel mode, which will obviously drastically impact memory bandwidth. The official support memory clock speed is 1066MHz, but Intel was quick to say that 1333MHz, 1600MHz and even 2000MHz memory kits will work on the platform.
