Which iMac/Mac Pro do I need to enable Realview?

Firstly let me apologise, because this is very likely in the wrong location. I hope not, but I've never seen a forum laid out quite like this one!

I am trying to find out which currently-shipping iMac has the proper video card to support Realview. Can anyone shed some light? I am aware that some earlier models were capable of running Realview with softmodded graphics card drivers. I would be fine with doing that, but obviously if there is a no-mod solution that would be even nicer.

If no current iMacs are capable of Realview then how about a MacPro? Does a currently-shipping model have the correct card? If not is there a card I can buy to put into a Mac Pro so that it will support Realview?

(I already have Solidworks running very nicely on an elderly Core2Duo iMac, but without Realview. The video card on that model is not softmoddable.)

Thanks in advance!
