As the title suggests I want to know which graphics card fits to my system the best. I am in a three way battle with the gtx 760, 770 and 780 and I want to know what fits best with a i5-4670k. I can afford any of these graphics cards, I just want to make sure I spend the money wisely and that it makes sense for the parts. I have not done any extensive gaming since I made the system last July, but I like to try to get the graphics as high as feesible with the integrated graphics. 1080p gaming is all I see myself using for the near future. I have a 750watt PSU by the way. Thanks ahead of time.
