I'm currently building a computer that I will be editing HD video and special effects on, and in addition to that I wish to game at max visual settings for as long as I can. The plan was to get a GeForce 770 for the time being then get another one to SLI them later down the line when it was needed. Would it be better/smarter for me to just get the 780, or maybe just one 770 is enough. I plan on gaming on one monitor.
If you don't have a limited budget it would be better to go for GTX 780 route. Yeah i know there is a price difference between a 770 and 780 but it would be a more future proof decision to pick the latter. Especially for you in production works. Also the 4GB versions of 770 are somewhat expensive. And there is the black friday soon, who knows perhaps you can grab a 780 for cheaper?
