I have an 800Mhz QuickSilver G4 with a 4x AGp slot that came with a stock GeForce 4 MX graphic card. Since I have a 17" Apple Studio LCD Display (awesome, by the way), I need to run games in 1280x1024 (its native resolution), or they look crappy. Trouble is, a lot of games run slowly at this resolution unless i turn the graphics pretty far down. Is it worth it to get a GF4 ti? They are kinda pricey... so my next question is: Can i put an (inexpensive) GeForce 4 ti for PC into my mac somehow? If it was possible, I'd be a very happy man.
