I am asking this on account of my dilemma of trying to decide on whether I want to buy a GTX 670 FTW 2GB or a GTX 670 FTW+ 4GB. I have researched and seen that the current performance does not differ much between the two models, but I know the requirements on games will continue to become more and more demanding. I am looking about not upgrading for around 5-8 years...
