Current Hardware:
PSU: OCZ 600w GameXStream
GPU: XFX GeForce 8600GT XXX 256MB 128-bit GDDR3
RAM: 2GB Dual Channel DDR2 4200

I am looking to get the following MoBo. I noticed though that it only has a single PCIe x16 slot. Am I missing out on something, is running dual cards not realy a standard as of yet, will I need to run dual cards before I am ready to upgrade the MoBo again?

Now for the CPU. I originaly was looking to snag the first CPU but it was recommended to get the second CPU to take advantage of the above MoBo. So, the question is then, do I pay another $15 and take the third CPU?

DDR2-533 ("DDR2 4200") is the wrong RAM for a 1333MHz FSB system. DDR2-533 runs at 266MHz frequency, 1333MHz FSB runs at 333MHz frequency...pair them up & the RAM will bottleneck the system.

If you have no intentions to overclock, you need DDR2-667 to be able to run the CPU:DRAM frequency ratio at 1:1. If you do intend to overclock, you should get DDR2-800 or better & manually configure the memory speed to maintain a 1:1 ratio.

"If you have no intentions to overclock, you need DDR2-667"

Ok, the RAM came out of my original PICe build from a few years ago I will pick up some 667.

Also, I got the answer I was looking for on the MoBo. Thank you.

Now as far as the CPU's is it a stupid question because I meant it to look that way. I just didn't know if I was missing something between the 2 CPU's and that is why the one that I see as the better one is only $15 more.

The $125 chip is an 800FSB, the other two are 1333. The more expensive on is faster.
