I use Rivatuner from Guru3d (www.guru3d.com). Not sure if that works for your friend or not.

Hard to say on overclocking the gpu/mem. I just kept turning it up until I saw artifacts / crashing. I'd jack it up and run a loop of 3dmark to see how it fares. Keep turning it up until you get a crash, then turn down. I reached 305/625 with my 4200.
