That seems like a huge amount of power and heat load to put into a non-gaming rig.
Haha, well if it isn't obvious by now, I'm not exactly an expert so I'd love to hear your 2 cents about what you would suggest. I feel like I'm pretty much all the way there due to David's suggestions, but as far as the GPU there's been a lot of confusion about which to go with if you have 3 monitors and are looking for a good CUDA GPGPU.
I have been cruising this list:

It seems like the 470 has so many more processors than the 450, which is why I was possibly considering doing that option I said above and getting a new card for my gaming rig. On the other hand, you're right that may be overkill I just don't have any experience with CUDA processing and CS5. Not to mention it would be burning a hole in my pocket.
