I've got a Gigabyte mobo which seems to have a heating problem. I'm dreaming of replacing the board and keeping everything else (socket A processor and pc-133 memory). Given the thousand or so boards to look at, is there a website which will help narrow the choices?

Am I asking too much? Am I just going to have to suck it up and spring for a 64 bit processor and new memory? Talk about spendy....
