I was wondering if the ps2/gamecube/Xbox emulators would work on my laptop.

I have a presario c552 with 2 gigs of ram and an intel celeron m processor.

I've heard that it's not powerful enough and that I need a dual processor(I cannot change that of course do to integration)

I've also have been told that certian games bog down my processor because my computer uses a 'virtual video card' instead of having a 'real one' installed.

Is there some sort of program or external hardware that I could use to help this?
