I have had some success with re-flashed GTX285 graphics cards, as have others.
Have had issues with some GTX285 re-flashed (not all) - just beware...
There is a UK source of these...
Nvidia Quadro4000 prices have dropped recently too - I think they are worth the money

I wouldn't pay the price for a PNY's Quadro FX4800 for Mac though! especially if apple manage to fix the ATI problem

You may also want to invest in a couple of DVI Parrots to manage the EDID/HDCP if running 10.6.x and above...
