    Nvidia GTX 770's in SLI are going to beat the GTX 780ti in almost every way except for things such as heat production, energy usage, weight, etc. Personally I would go with SLI GTX 770's since Nvidia fixed the micro-stuttering (where one GPU renders faster than the other one over the SLI bridge and causes micro-lag). Also, what are you trying to run? A GTX 780ti is enough to run up to 3 monitors, only use for SLI is for showing off/video editing/high performance computing.
  2. I am going to be playing games like Crysis 3, BF4 on ultra at 1920x1080 on 1 monitor @ 144Hz, also I am getting the parts in the US because I live in the UK and am visiting New York and they are much more cheap in america. Do I have to make sure the PSU has a red voltage switch? and If I buy peripherals such as Keyboard, Mouse, Monitor will they work in the UK because I heard something on the monitor about NTSC/PAL and Voltage rates? Could I blow my monitor and/or not recieve a signal?

    In that case, I would recommend you find the UK version of the power supply, since the difference of 120 Volts will destroy the power supply. So yes, you will need to find a power supply dedicated to 240 Volts or a voltage switch. For the keyboard and mouse, it shouldn't have any issues, as they are over USB with a universal +5V electrical input. For the monitor, I would also recommend finding a dedicated UK one, just to make sure it does not have any compatibility issue, as some do and some don't.
