Are these parts compatible

[Daedaless]

Hi I am building a new system by upgrading almost all of my computer parts. I was wondering if these components are all compatible with each other:

Graphics card:
Radeon HD 4850 X2 2GB 512-bit (256-bit x 2) GDDR3 PCI Express 2.0 x16 HDCP Ready CrossFire

Processor:
Radeon HD 4850 X2 2GB 512-bit (256-bit x 2) GDDR3 PCI Express 2.0 x16 HDCP Ready CrossFire

Motherboard:
ASUS P5Q-E LGA 775 Intel P45 ATX Intel Motherboard - Retail
8-Phase power optimize OC crossfireX, 2x LAN, stack cool 2

Memory:
G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Dual Channel Kit Desktop Memory

Power:

Hard Drive:
Seagate Barracuda 7200.11 ST3500320AS 500GB 7200 RPM 32MB Cache SATA 3.0Gb/s Hard Drive - OEM

Monitor:

The total cost is $1300. Any suggestions or things I should change? thanks

p.s will I be able to combine the power of both my graphics cards for one really good image or is it only practical for 3 or 4 screens?

Well running a 26'' monitor will probably require a huge resolution. So it's good that you chose a 4850x2 as your gpu. However, you didn't put what your cpu is gonna be. You double pasted. Based on what you put up here I'm guessing that you'll be getting a quad core or a new C2D. It will run two screens fine, not sure if your particular card model will support the dual link DVI allowing four screens.
