Thanks for the info.
But *ouch* for the price: 400 CND$! For an empty box with a slot and a fan?
Seems my needs fall between the cracks of apple products: don't wanna pay for that giant 5K 27in screen on the iMac (and 21 is just too small), but the Mac Mini has no GPU grunt.
Hopefully the next Mac Pro won't be too expensive and I'll be able to think about its cost as a long term investment (at least, longer term than the mini or imac).
