I'm looking for a new processor and mobo for my desktop to replace this craptastic Pentium D. I'm undecided whether I should go intel or amd. I guess really what I am looking for:

-low heat output(the computer room is about 5 degrees warm than the rest of the apartment)

-preferably under 200 for both a mobo and cpu

I guess im mostly just wondering about the power/heat and what kind of processor to get

Thanks!
