Building an HD Video Editing computer. Are these parts compatible?

APPROXIMATE PURCHASE DATE: Within the next two weeks

BUDGET RANGE: 1,000 - 1,600

SYSTEM USAGE FROM MOST TO LEAST IMPORTANT: HD Video Editing in Adobe Premiere and Adobe After Effects, HD Rendering in 3ds Max, as well as some gaming.

PARTS NOT REQUIRED: Keyboard, mouse, monitor, speakers, hard drive

PREFERRED WEBSITE FOR PARTS: Any

OVERCLOCKING: Maybe, I've never done it before.

SLI OR CROSSFIRE: Maybe, but if one card can run most games well then I'm happy at that.

MONITOR RESOLUTION: 1280x1024, however I may upgrade later on.

ADDITIONAL COMMENTS: I don't care what the computer looks like, but I do want it to be as quiet as realistically possible.

I have picked out some parts on Newegg that I -think- will work out nicely, but I have zero experience building my own computers. These are the parts I've got my eye on:

Are these parts compatible, and would you agree with these choices? Also, I'm buying another copy of Vista because I've been told that I cannot install my current OEM copy on a new computer - is this true, or is there a way to deactivate this current installation so that I can use this copy on the new machine?

As I mentioned my main goal is to be able to edit HD Video as efficiently as possible. This is my first upgrade in almost 6 years, so I'd also like to catch up on some of the games that have come out since then and recently just to see what I've been missing.

Thank you very much for your help! I appreciate it

http://www.adobe.com/products/premiere/systemreqs/ states that you require a quick hard-drive subsystem (RAID0) or equivalent SCSI. I don`t want to be devil`s advocate around here but you realise i hope based on your picks that the hard-drive will be the bottleneck here. Maybe a couple of fast sata drives (2-3) would be good.
The motherboard is decent and has IEE1394 if you want a quick interface with a HD camcorder.
Also, where is the Blu-Ray burner? Are you runnin` an external solution or is something that i`m missing here?
I agree with Proximon regarding the graphics solution and PSU (although as PSU Seasonic M12D850W would be a good competitor).
Quiet as a mouse ....hmm. That`s hard. Put some pasive coolers around hard-drives, rubber gromets. Unfortunatelly Adobe is not playing nice all the time with flash-based drives, because i would recommend `em for low wattage, performance and lack of noise.A good start would be http://www.quietpc.com/gb-en-gbp/p [...] solutions.
A good case would be http://www.newegg.com/Product/Prod [...] 6811129043 but it`s a bit pricey. Great cooling with loads of 120mm fans that can be set at low spin (lack of noise) and a 200mm fan on top spinning at low rate. You can replace `em with some Sharkoon Silent Eagle 1000 (120mm) 20.7dBA and Antec Big Boy 200 for 200mm one.
CPU cooler you can try Cogage True Spirit from Thermaltake, quiet and decent.
With the airflow sorted you can try to soundproof your case http://www.quietpc.com/gb-en-gbp/p [...] materials.
Well, it took me quite a bit to finish .
If you feel a bit more courageus you can have a look at a watercooling solution or a case that has all the piping done and sorted.
Good luck.

A monitor resolution with 1280x1024 will see little gain with the gtx 295. maybe you want to take that into consideration if you havn't already. If you still need to go with a heavy hitter, the 5870 might be the better choice, but the 5850 is looking really good at 100 bucks cheaper than its big bro. Later down the road you could cross fire two 5850's once you have your monitor upgrade. Heck, if you are really ambitions jut by 5 more 1280x1024 res monitors and you could have a pretty unique setup. Probably need a little more juice to actually game on a 7680x1024 rig though. Also the 4850 draws considerably less power than the gtx295. It is even less than a 4870 in both idle and load situations.
