This is my current setup. I play on a single 1080 monitor right now so I can play most games at Max although some games like Far Cry 3 I have to lower the AA settings to 2xMSAA for good FPS(45+) for me. I used PCpartpicker to make the list so the HDD and DVD/CD drive are place holder. With this setup can I power a 780ti? My PSU is 3 years old and those dang PSU calculators and cap aging worry me. And should I get one? I'd really like to wait for the 800 series but the upgrade itch is getting harder and harder not to scratch.
