so as the holidays come around i find myself wondering if I should buy a gtx 780 to sli with my other gtx 780 (it will be used, id spend around 300$ for it) or if i sell my gtx 780 for 300$ and go with the new 980 or 980ti. I have a 1000w psu and I live in a place where power is cheap so the added power draw of sli is not a factor for me. Furthermore I have a large case so the heat created wont be a factor. I plan on buying a 2560x1440 monitor. wondering what would be the best decision for me.
