For the parts quoted above, the only thing I agree with is the NH-D14, as that is not a video editing rig by any means. Celcoid has the right intentions, but is doing a disservice to people by recommending those parts for video editing.
First things first: You should go with a 2600K, and you are better off with a 570 as you will IMMENSELY benefit from CUDA.
Secondly, I'll point out the obvious fact that programs like Adobe Premiere do not recognize a 2nd card in video editing, and ATI is simply not an option in a CS5 environment. Yes, it'll get the job done, but NVIDIA will do it WAY better, and faster. Premiere Pro was built WITH CUDA, and is optimized with the Mercury Playback Engine, and guess who will run it better? That's right Nvidia cards.

Watch this video for MPE in action:
No, you don't need that Quadro from the video, the 570 will give you excellent performance.
My rig is a video editing machine, and I have done thorough research on the topic, don't waste your money going with ATI for the GPU, or going with that 875k, and you definitely do not need 2 SSD's, No Offense but I never seen so much wrong info in one post for its intended purpose. My suggestions:
CPU - 2600K - $317
MOBO - TBD $150 - $200 ( See my sig for reviews )
RAM - 8 GB Gskill - $109
Tighten up timings to 7-7-7-24
GPU - 1 570 @ $349
Cooler - NH-D14
HDD's - 2 x 1TB F3's - to be used separately, 1 as your scratch disk, the other as your rendering drive.
1 SSD as your boot drive - if you can wait for x25m 120GB to come back in stock, otherwise, that other Vertex 2 is fine - http://www.newegg.com/Product/Produc...-035-_-Product
If you'd rather go with the x58 platform, see my sig rig. Edited by 2010rig - 1/3/11 at 1:32pm
