When I built my PC last year I just threw in a 560 ti because I ran out of money lol. Also back then I was only playing WoW and figured that was more than enough seeing how a Commodore could probably run WoW. Now that I am playing Tera and Im sure future games like TESO I think its time to upgrade to something with more power. I was at least smart enough to not gimp on the power supply to allow for a future upgrade and got 750w. My mobo is an Asus P8Z68-V Pro Gen3 LGA 1155 and I have an i5-2500k OCed to 4.32 GHz. Just wondering how good of a GPU I can get before I am bottle necked by my CPU or something that wont even fit on my mobo. I prefer NVIDIA over AMD.
