My rotation at lvl 41, goes like this: Elite: Tracer -> Tracer -> Tracer -> Unload -> HeatSeeking -> Tracer -> Tracer -> Rail Shot After this i just spam Tracer and Rail, and Unload when ever buff pops. Non-Elite: Death from above -> Sweep -> Sweep -> Finish them with Tracer and Rail.

I run SWTOR with 1 GTX560Ti and i have all on max and no lags. Concerning the above comment about the price, u can check every forum 560Ti gives u more value for money. I can recommend MSI GTX560Ti (2GB version if u are running Full HD)
