Ive been browsing the boards for a while doing my research, but there are a few lacking compelling arguments to convince me over which items to purchase. Any clarification would be great.

CPU: Phenom II x4 955 3.2GHz
Graphics: Either GTX 470 or Radeon 5850 (Which one will better suit my needs/pairs with my processor?)
RAM: 4GB (2x2GB) G.Skill 240 PIN DDR3 SD 1600
HDD: Spinpoint F3 500GB 7200RPM SATA 3GB/S

I need help filling out the rest of my build with compatible, quality parts that give overall balance to the machine.

Mobo: ? What is compatible with my processor/video card? do I need to look into crossfire boards?
PSU: ? Hopefully someone can recommend a good combo deal with a PSU and case. I think I need at least 750W.
Case: ? See above. I'm willing to spend a few more dollars on a quality case with a decent cooling system if need be according to the graphics card.

Once that's all sad and done, do I need to look into any sort of cooling unit, or will a decent case provide all that is needed?

Thanks much in advance!
