I'm not a programmer or expert user, so go easy on me please.

I have an old athlon machine that can generate ~1850 khash/s. I have a geforce 8500 gt on that machine, and used this to up production to ~2150 khash/s (says GPU 2150, so I know I'm using the -gpu). How can I get these 20,000 khash/sec that everyone else is? Is my athlon the bottleneck here, or can I just buy a nicer video card?

For Cuda I think (emphasis on think, not know) the best thing to look for would be the number of Stream Processors, which is like the number of cores. If you are using an old Athlon and your stuck with agp I think this will slow you down abit vs a pci-e bus but, I really don't know. Also you would want to make sure you cpu can keep up with pumping data to your gpu. Like I said in my post one of my cpu's cores is pegged @ 100% usage while the gpu crunches away.
