First, what types of games do you intend to play with your new graphics card? There will be a pretty big difference in the price and model depending on if you play games such as modded Skyrim or ac4 on max settings and/or multiple screens vs. playing Minecraft with your friends, older games, etc. Since you are complaining about heat, I would recomend one of ASUS's direct CU2 cards, as I hear that they are pretty good at staying cool. I personally have the msi gtx 770 w/ a twin frozr cooler and 2 gbs of ram, and that works very well(60 fps on almost any game that I play on my 1920x1080 monitor) and almost never gets loud or overheats, unless overclocked. I would say that
