I'd say there's a tie between your video card and your RAM. Upgrading either one would result in greater performance not just in ePSXe but pretty much any other application you run as well. Given that I don't live in Asia I can't say for certain, but right now RAM prices are relatively cheap. If you've some cash to burn and would like to see greater performance immediately, get more memory.
Secondly I'd upgrade both my mobo and processor. Generally you can get a good deal if you buy a bundle (that is, the mobo and proc in one package), especially if you consider getting anything from AMD. As I mentioned in a thread before, for just about any non-scientific/mathematical use AMD can't be beat price
erformance-wise.
