I'll present an alternative idea, why not upgrade your motherboard? You could even use your existing CPU to save some bucks, but you'd end up with a real upgrade. Motherboards also come with the latest BIOS, many have USB 2.0 ports, etc.
I just bought the Acer AX4B-533 Pro for around $90, it has 5.1 sound, 10/100 Ethernet, USB 2.0, and of course, a new and up to date BIOS!. My processor cost twice what the MB cost.
