Can I connect the Apple Thunderbolt display to any PCI Express graphics card with Mini DisplayPort v1.2 Eyefinity technology?

You'll need a graphics card that can output Thunderbolt (if such things exist, I have not checked). The Apple Thunderbolt Display can only accept input in the form of a Thunderbolt signal, Mini DisplayPort will not work.

Apple does sell a Mini DisplayPort variant of their 27" display, so if you don't yet have the display you should get that instead

Yes, this is correct. Unfortuantely, the answer is no. – CajunLuke Mar 30 '12 at 18:00
@CajunLuke The "M" in "Mini DisplayPort" is capitalized – Kyle Cronin Mar 30 '12 at 18:02
Well, damn. I'd swear I saw it lowercased consistently awhile ago. I must have been thinking of the Mac mini and iPod mini where it most certainly isn't. Now I have to go back and re-fix all the questions I "fixed". :) – CajunLuke Mar 30 '12 at 18:07
There's a small note on the Thunderbolt product page: Customers with Macs that only support Mini DisplayPort output, such as the Mac Pro and MacBook, as well as previous generations of MacBook Pro, MacBook Air, Mac mini, and iMac can use the 27-inch LED Cinema Display. – Bill Brasky Mar 30 '12 at 18:11
@HerrKaleun Correct – Kyle Cronin Mar 31 '12 at 6:31
