Might be best with a pair of GTX670s? And then maybe incorporate a new motherboard and CPU and RAM into the upgrade? The Phenom II was never really that fast.
2 important questions will be:
1) What is the most intensive game you want to play?
2) How much do you want to spend?
Thanks for the replies,
1) I'm not really sure how to answer 1st question.. I play all the big title strategy games, Simcity is coming out soon that I would like to play in Max settings, Arma III, So im talkin 2013 releases at nearest to full graphics ideally.
2) Money well I guess its not really an issue, but don't want to wast it on something not needed. My current cards cost a total of £330 so I guess between £400 and £500 for an upgrade would be ideal.. but its flexible.
I was thinking of grabbing some more ram possibly 12GB but im not sure ill ever use that much, I rarely encounter much issues with 6GB. I haven't considered swapping my mother board or CPU, I havent really had much issues regarding them.
