Unless the program (and OS, although all versions of XP are) is written to take advantage of either Dual Core or multiple processors, then you probably won't see that much advantage.

Whien I switch to Dual Core, both Premiere and Encore felt a lot more responsive, and rendered faster too.

From what I have read, the 775-vsta isn't the fastest motherboard, but it is the only one I know of that supports AGP graphics cards (which was a consideration for me, as I didn't want to spend a lot on a graphics card with DirectX 10 cards around the corner).

I have to admit, if I have the money when I do get a new graphics card, I may replace the board as well, although probably not.

One other thing to note: Even if your software isn't coded to take advantage of multi cores, then you will still get some advantage from the enhanced multi-tasking (given two cores, and two processes, Windows will generally run a process on each core).
