ADDITIONAL COMMENTS:


I've got a decent rig, which includes
- Asus M3N78 MB, with 6GB DDR2
- XFX GTX 260 Black Edition
- 850 W PS
- AMD Phenom II X3-720 Black Edition

It plays the new games well, and it is generally fast. Therefore I don't see a reason for upgrade until DX-11 rolls out.

However my case sucks since it barely fits the video card, and the air flow is abysmal.
There is no room for a big heat sink required for serious OC.

In the future, I'll probably upgrade MB to DDR3, maybe Intel I7 with DX-11 card, but it seems that's a project for next year

My immediate goal is to solve my severe lack of OC capabilities, so I figured I should invest in the following
- Case, which is big enough for any future MB I might pick (preferably ATX-E compatible)
- Big heatsink, preferably compatible with both AM3 and I7 sockets
- 120mm heatsink fan.

I would like to hear your opinions on the following components I've found
- Cooler master case HAF 932

- Thermalright heatsink Ultra-120 Extreme

- Bgears b-COOL BR 120mm Case Fan

I don't mind spending a few bucks on these, as long as I can reuse them for future builds.

Thanks
