Same speed or double the frontside bus of the processor. That's all you need to worry about - and even then, the speed differences caused by mismatching bus speeds are minimal.

Doubt it will make much a difference. The North Bridge is the part of your PC Bus that deals with CPU to RAM & video card communication. So long as you make sure your RAM is operating at the full Bus speed your Performance should well be optium for your equipment. If your looking into high performance tasks that might dictate your processor and its L1,2 cache size & of coarse your motherboard bus speed. If your really about optimizing downloads, internet, and that kind of stuff that will probably filter on average though your South Bridge and well hardware doesn't really matter as much as configuration and OS. (Example: 64 bit windows has a optimized TCP/IP stack that improves Web Performance). A good site for hardware might be PC Perspective which has a show on the TWIT network.
