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.

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