Im making a new rig and want help deciding between graphics cards. Im stuck between 2- GTX 770s or 2- 970s. The new 970 is only a little more and im willing to pay the extra money to help future proof me a little bit. Another thing is that i would like to have them run off a good quality 750W power supply. will this be enough to power the two monster cards? any help would be much appreciated, im fairly new to the pc gaming world.
