Custom Mac Pro RAM

[pmodernme]

I'm working on a mac pro build based on your specs, with some tweaks from lifehacker. I plan on using it primarily for FCP/Color/Photoshop (large image sizes). Here it is so far:

Gigabyte LGA1366 SATA3 ATI CrossFireX ATX Motherboard GA-X58A-UD3R
Intel Core i7 950 3.06GHz 8M L3 Cache LGA1366 Desktop Processor
EVGA GeForce GT 240 Superclocked PCI-Express 2.0 Graphics Card 512-P3-1242-LR
2x Seagate Barracuda 7200 1.5 TB 7200RPM SATA 3Gb/s 32MB Cache 3.5 Inch Internal Hard Drive ST31500341AS-Bare Drive (in raid 1 configuration)
OCZ Technology 120 GB Vertex 2 Series SATA II 3.5-Inch Solid State Drive (SSD) OCZSSD3-2VTX120G (system drive)
Antec Three Hundred Gaming Case External 3 X 5.25; Internal 6 X 3.5 2*Usb2.0
Corsair CMPSU-650TX 650-Watt TX Series 80 Plus Certified Power Supply

I'm having trouble picking out RAM. I'm looking at cards compatible with the motherboard, but I noticed that the specs for the CPU say DDR3-1066, not DDR3-1600 (which most of the DIMMs I see on this board, and the guide are). Can I use these?

Kingston HyperX 6GB (3 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model KHX1600C9D3K3/6GX

They're compatible with the motherboard. But are they compatible with the CPU?

I run 1600 RAM with no worries. I'd recommend my RAM but read up on that model just to check if anyone has had any issues.

I'd also recommend my card and don't know where the nVidia cards are up to with compatability as I know some of them were giving issues in OSX but that might be the higher end ones.
