That is a very nice rig you got there. Im just wondering but what do your temps run under load.

Im thinking about sticking with air cooling at least for now. If i decide to get a new case there are now several manufacturers that make cases that come with bigger fans (120mm) and some of them come with 4 and can have more added (like the CM Stacker and Antec 900/1200 series). But if i ever decide to water cool.....I will know who to talk to first.

Oh and also, what are the main differences between the 32bit and 64 bit besides the ram allocation? Will all 32 bit programs run on 64?
