Help on photo/video editing computer

[george2005]

I want to build a computer system for photo/video editing purpose.

I will use Nikon CaptureNX2 and photoshop CS for photo editing.
I will do a lot of decoding and encoding on 1080i/1080p videos.
Many internet surfing.
No game play.

Many of the configuration here is for gaming which could not help me much.
Can anyone suggest me a configuration to maximize the performance of photo/video editing?

1. I plan to buy 2 SSD with RAID 0 configuration for the system drive. So the motherboard should support RAID0.
2. I will add 4 more hard drives (I already have) into the system. So the computer case should have 6 3.5" drive bays.
3. Can I get any advantage from i7-920 CPU?
4. Can I get any advantage from tri-channcel DDR3 memory?
5. I just got help from ATI forum that HD4670 is a good enough graphic card for my work, so the PSU only need support HD4670.

Thanks so much!

Is there any unwise idea in the plan?

You may want to downgrade the PSU a little bit more. Though it would be fine if you want to buy another graphics card for gaming soon.

how about change it to:
CORSAIR CMPSU-450VX 450W ATX12V V2.2 80 PLUS Certified Active PFC Compatible with Core i7 Power Supply - Retail
http://www.newegg.com/Product/Product.aspx?Item=N82E16817139003

or
CORSAIR CMPSU-400CX 400W ATX12V V2.2 80 PLUS Certified Compatible with Core i7 Power Supply - Retail

Is it OK even I add 4 hard drives more?

According to the Newegg site, the CX400 have 6 SATA power connectors which I think would be sufficient for your needs.
