I don't know what you mean about bugs. My 64 bit box hasn't crashed a single time since I installed it, and its only been turned off once to go on vacation. Everything works perfectly and as advertised.
Broadcom has the NIC drivers on their site for my NIC. Easy to find.
nVidia has a full array of 64 bit drivers available on their site, also easy to find.
Creative is the same deal, no problem finding them there.
Everything else was already included in windows.
