I have a GTS-250 I want to buy a video card that will actually be supported by MPE BUT I have a hackintosh so I need to get a video card that is Mac compatible. Is the GTX-285 pretty fast as far as MPE goes? I dont see me having the money for a quadro plus I just do weddings.

The GTX 285 is a perfectly good card for MPE , but you may have a difficult time finding one, since it was EOL about 5 months ago.

I have a rare GTX 285 with 2GB RAM on it. I'd be willing to trade for a 470 or 480 if anyone is interested (just throwing it out there!).
