Hi all I'm about to set up my new rig, and just waiting for haswell to be released. I'm looking for a new gpu and considering between the 7970 6gb vapor-x or the titan. Obviously my pocket is favouring the 7970, but I would like to hear other opinions. Will be running three 23" screens and intend to go on iracing, but definitely F1 2012 and rfactor2 etc... I understand crossfire won't work well on F1 2012 so that's a concern if I get the 7970, I can't get another card sometime down the road... or should I just a get a 3gb version? Thanks! !!
