Yes, FSAA = Full Scene Anti-Aliasing, and the V5 has great FSAA.
Likely the bottleneck is not your video card, but your CPU. That particular CPU has a crappy floating point math unit, and that is something that AH in particular relies on heavily.
In your BIOS, you should be able to disable your onboard video and get that 8 megs back.
Get into your video properties and look for the DirectX settings tab. Try it with "Fastest" (no FSAA), 2xFSAA, and 4xFSAA just to see the difference. I run mine at 1024x768 32 bit with 2xFSAA on an Athlon 700. FSAA on the V5 rocks, you'll love it trust me. I couldn't live without it.
You should be able to get to higher resolutions, color depths, and maybe even use 2xFSAA without going any slower. However, I seriously doubt the game itself will run any faster with that CPU in it. Try different settings and see what works out. I think you'll see your video quality increase, but the speed will stay the same.
I don't know right off what form factor that K6-2 used, but just about any other chip you could put in there would do a better job than the K6-2 will. A cheap Celeron would give you a nice boost in speed I'm sure.
