Hello.

Gonna throw in the dxdiag from her laptop: http://www.mediafire.com/?1yerp0l4rjrijrw

Key specs: 2nd Gen i5 2410M
AMD Radeon HD 6470M
6GB RAM

She only just recently purchased it and it runs Sims 3/Call Of Duty Mw3/Orcs Must Die without sweating, I've tried lowering it to directx 9 with lowest resolution settings, it still lags/fps drops.

Merry christmas ! Wish you all happy holidays!
