I am looking to upgrade my GPU to an SLI configuration and would like some input on which I should go with.

I'm upgrading from an EVGA 680 GTX SC. I'm looking to upgrade to SLI. I've made up my mind and it's either going to be an SLI setup with the EVGA 770 GTX SC 4GB or the EVGA 780 GTX SC 3GB. I had originally wanted to do SLI with the 680's but I'm not paying $300 for a used card when I could sell my 680 for ~$300 and get two brand new 770s for a little bit more than I could one used 680. So I've come to the conclusions that I'm going to SLI the EVGA 770 GTX SC 4GB or the EVGA 780 GTX SC 3GB. I'm just not sure which. The EVGA 770 4GB's are $400, the 780's are $500. I'm wondering if the increase I'd get from upgrading to the 780s would be worth the additional $200 price tag. I do a lot of gaming and I want this set up to be able to max the games that are coming out for the next four years or so. I also just bought a Seasonic-X 750W Fully Modular PSU and I'm curious to know if that will run the 780s. I know it will the 770s for sure.

Here is my build:

Disregard the 780s. I currently own everything on that list, except those. I was just seeing what it would look like with the 780s.

Also, I will be using a high resolution monitor or a multi monitors in the near future (probably the next few months).

I would go for GTX 780Ti single card. A single powerful card is better than SLI. Requires less power, hassle free setup, no micro shuttering.

I've heard that microstuttering really isn't a thing anymore with the NVIDIA cards so I'm not too worried about that. And I do want to SLI. Not really interested in the TI version of the 780.

Measured power consumption GTX 770 single card

1.System in IDLE = 119 W
2.System Wattage with GPU in FULL Stress = 303 W
3.Difference (GPU load) = 187 W
4.Add average IDLE wattage ~10 W
5.Subjective obtained GPU power consumption = ~ 197 Watts

GeForce GTX 770 2-way SLI - On your average system the cards require you to have a 750 Watt power supply unit as minimum

Power Consumption GeForce GTX 780 2-way SLI

1.System in IDLE = 129W
2.System Wattage with GPU in FULL Stress = 617W
3.Difference (GPU load) = 488W
4.Add average IDLE wattage ~20W
5.Subjective obtained GPU power consumption = ~ 508 Watts

GeForce GTX 780 2-way SLI - On your average system the cards require you to have a 800 Watt power supply unit as minimum

Can be done on 750W PSU.

780s can or can't be done on a 750W PSU? If not I'm sure I can sell the one I just bought. Also out of the two which would you recommend?

Gotcha. Makes sense. How much of an increase is 780 SLI over 770 SLI?
