It seems to be running fine, however, having never built a system before, I want to make sure its running properly.  I'm running vista home premium 64bit.  How do I check my temps?
Also, I have an EVGA 780i mobo, E8400 cpu, 4 mgs of OCZ Reaper ram, and the BFG 9600 GT vid card.  Should I add another 4mgs of ram, which is relatively cheap to do.
