Hi, i want to buy a new graphics card for my system and after a lot of concideration i came up with 7970 and 670. I am from Greece and they both are at the same price. I want to play mostly strategy games and especially Rome Total War II but since i am willing to spend a lot of money, i want to be able to play at least all the new games in very good graphics... Which one of these two do you recomend? I will play on a 1080p monitor and i may also oc a little.. Thank you in advance!
