Hi all, first time poster.

I'm building a budget machine for a friend and I ordered the parts on Newegg yesterday. I think I might have made a little flub though. I've built my own machines in the past, but I haven't had to for a few years now and I am definitely out of practice and have never been an expert on the subject. Here are the machine specs:

Motherboard: GIGABYTE GA-G31M-S2L
CPU: Intel Core 2 Duo E7200 Wolfdale 2.53GHz 3MB L2 Cache
RAM: G.SKILL 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Dual Channel
Video Card: EVGA 512-P3-N954-TR GeForce 9500 GT 512MB 128-bit GDDR2 PCI Express 2.0 x16
Power Supply: TOPOWER TOP-550PCM 550W ATX / BTX
Case: COOLER MASTER Centurion 5 CAC-T05-UW

His brother got him a hard drive recently, so I'm just gonna use that for the install, though I have no idea what it is atm.

My question basically comes down to whether or not the Motherboard is up to snuff for the CPU / RAM I bought. I was under the impression that for best performance you should match CPU FSB speeds with RAM speeds. I had originally configured the system with DDR2 800 RAM and a much cheaper processor, but my friend wanted to go bigger with the CPU so I went for the E7200. I didn't think about the mobo though in doing so and the "memory standard" as listed on the specs is DDR2 800. Will the mobo run the DDR2 1066 sticks at DDR2 800 speeds? Will this effectively make the machine run in a suboptimal fashion?

Honestly, I don't think it's a very big deal, but I could wrong. At the very least it makes the 1066 RAM a foolish purchase I would think... Should I return the mobo and try to find one that would better suit the CPU / RAM speeds?

If you run the memory unlinked (which the motherboard should allow, though I'm too lazy to check for you) then you can control the CPU speed and the memory speed (in the BIOS) independently of each other.

You don't need to match cpu fsb with memory fsb. On the g31 board, you 1066 memory may run at a lower speed.

If you plan on overclocking, you may need the faster ram, as this mobo doesn't offer a 1:1 FSB:RAM multiplier. So overclocking the FSB to 300, requires 800 RAM, etc.
