That sucks, you're still hanging on to an old Socket 478 system ....
Oops, I guess I'm the kettle calling the pot black.
Anyway, you have an Intel board, so save for more advanced methods like pinmods, you won't be able to overclock. You should be able to overclock your GPU with Rivatuner, but honestly, it's not even worth it on a 6200.
If your income could support a whole new system if you inadvertently kill your current one, I (be an eternal tinkerer) would definitely try the more risky overclocking methods like pinmodding. It'll be educational, and in my mind, fun! Good luck, but the gains will be minimal, and might not be enough to perform the task you wish of it.
