I don't have money to replace my entire rig and it is fine for the games I play (Skyrim, Total War @ 1080p) so please do not recommend that. I currently have a gtx 570 that I have to slightly underclock to keep cool/stable. I also have to max out the fan 100% once the GPU goes above 75C. That means playing games gets VERY loud. LOL. Now mind you, I only have a q6600 so I don't want to buy something like a gtx780 that will be crippled by the old CPU. I am looking for something that will be somewhat faster than the gtx570 but MUCH MUCH quieter when performing at an equal level. Also, it must be NVIDIA. Thanks!
