The main issue being the card seems to only use 3.5gb max in most games and in the games where it goes over that (Shadows of Mordor) it causes serious performances issues, however this doesn't happen at all on the 980 which is able to use the full 4gb without any problems as has been tested by people on various forums including this one I think.
It's not specific to this card and it seems to be all 970s.
Ah OK, I found the issue described in the thread http://forums.overclockers.co.uk/showthread.php?t=18624935. According to http://techreport.com/blog/27143/here-another-reason-the-geforce-gtx-970-is-slower-than-the-gtx-980, it's a hardware limitation, not a driver problem. Even so, I'm still considering a 970 as my monitors are 1920x1200, and a 980 is £150-200 extra. I'll also look into getting an R290 or just waiting for the next generation of cards. Thanks for the heads-up.
