Hi ok just added a second 580 and am getting great fps in rift (my main game atm) and it runs just fine, only prob i got is when i try to run a bench ....heaven or 3dmark11 i get the dreaded "gfx drivers has stopped responding and have recovered" i used to get this some time ago when i had a single gfx card and never got to the bottom of the problem, it sorta sorted its self out with a driver update any ideas what might cause this just on benches my gfx is oc to 850 core and 2048 mem with 1000Mv
Thanks
Thanks
