Welcome to the forum. First off, is this
the motherboard that you own? If so, I would not recommend switching motherboards. For Socket A CPU's, that is a very good motherboard, especially with the dual channel capability. The Abit NF7 line of motherboards is also a very good (especially for overclocking), but in my opinion not worth paying extra. Your motherboard is very good, and I would stick with it. However, when you say "upgrading", do you mean simply getting a new motherboard, or upgrading your CPU, motherboard, and other components?
