You can get a quadro fx 4800 off the mac store for ~$1800... but it doesn't come as an option, so you'd have to buy the default card and swap out I guess... which makes it even more expensive. It was stuff like that that made me decide to get a pc instead of a mac pro... the specs I priced out for mac and pc put the mac at over $2000 more expensive than the pc for the "same" components...(xeon vs. i7, but with same clock speed)... over $5000, and that wasn't even with a quadro!!
