OK. After weeks of research here are all the parts I ordered. I want to check with you guys one last time that I can use these parts to dual boot snow leopard and windows.

Case: Antec Twelve Hundred

Motherboard: Gigabyte UD3L

RAM: Patriot Extreme Gaming Series 4GB (2x2GB). I got a total of 2 of these for 8 GB

Power Supply:Corsair CMPSU-750HX 750W

CPU/Processor: Intel BX80569Q9650 Core 2 Quad Q9650 Desktop Processor

CD/DVD Drive: Pioneer Black CD/DVD SATA

Hard Drive: Western Digital 640 GB Caviar Black SATA 7200 RPM 32 MB Cache

Graphics Card: EVGA 9800 GTX 1024 MB Cache.

I got a screen, 16 gb flash drive, and speakers too, but I don't think I need to worry about those. So all of my parts are compatible correct? Please tell me if something is not, I need to know ASAP if it is not so I can replace it.
