We live in interesting times if i understand the current dynamics. If you go to video editing sites they recomment nvidia for compute minimum gtx 570 or 580s. These cards are EOL and there may be a small bargain window here. The new 600 series appear to have the compute function severely restricted, which will push compute use to professional workstation cards like the 4000 - a lot more $$$. On the other hand the new AMD cards from 7770 up appear to have the compute function significantly enhanced (but perhaps not mature in drivers or apps) and not restricted. This leaves me undicided in which way to go, should I look for a gtx580 bargain (but older tech), go for a AMD 7000 series card or be pushed into the w/station cards?
