Case, Motherboard, Ram, and Processor Recommendation?

[used]

Ok I have $900 to spend building a new system, and I have everything I need except a case, a motherboard, some ram, and a processor. This system will be used mainly for gaming.

I have a Coolermaster Cosmos 1000 picked out for the case and an E8400 Wolfdale (that I will overclock) for the processor.

However, I have no idea what motherboard (must have PCI e 2.0) and ram to get. I'd been thinking about a Gigabyte X48T-DQ6 with DDR3 (1800) ram or sticking with a ASUS P5Q Deluxe and DDR2 ram.

Any suggestions?
All recommendations welcome.
Thanks in advance.

Go for DDR2 RAM definitely,because teh difference between DDR2 and DDR3 isn't much (and DDR3 isn't worth the money)
Also why it must have a PCI-E 2.0? Do u want SLI/CF? if so then go for a 780i board (for SLI) or X38 and X48 (For CrossFire) otherwise go for a P35 board.

For RAM go for a DDR2 800 RAM with 4-4-4-x or lower timings.

What kind of video card do you have? Do you have one, or two?
What kind of PSU do you have?

GA-EP43-DS3L - $100, one PCI-E 2 slot
GA-EX38-DS4 - $225, two PCI-E 2 slots (Crossfire), RAID

If your video card is an nVidia, get the DS3L, don't try SLI.
If it's an AMD, get the DS4 and do Crossfire now or later.
The difference is that Crossfire on X38 is much safer than SLI on an nVidia chipset.

RAM: 2x2GB DDR2-800 $80

Nice case and CPU.
