Thanks for the feedback guys. I've had the copy of 32-bit for a while since by previous setup was 32-bit, but since my CPU died I had to replace it and the motherboard. I went with the 6GB of RAM because of the triple channel memory and I didn't do the research to see if it was necessary or if 4GB could run in triple channel or if it would drop to dual channel and I'd see a performance hit, so I went with 6GB triple. Of course, Win7 32-bit only uses 3GB of it so it feels like a waste of resources, which is why I'm considering getting 64-bit. As a student, I can get a copy of 64-bit for $34US, so it's not an issue of expense.

I didn't want to wait until Monday to get the copy of 64-bit so I installed 32-bit on Friday when I installed the new motherboard and CPU. Now it's a question of whether or not it's worth it to re-image again to install the 64-bit and all of the updates and programs.
