Two questions!

[TAV]

Hello guys, i want to ask 2 things:

FIRST: my rig is good enough to play (fullspeed) almost all games in dolphin?

C2Q Q9550 2.83 GHz
MSI GeForce 9800 GTX+ OC
Asus P5Q-E
4GB RAM DDR2 800 MHz

SECOND: in some revs like 3789 and 3914 i got 60fps, but in the lastest revs i got only 30 fps (like a fps cap, but the framelimiter is off). U guys know why?

Thanks!
