I bought gtx 780 evga sc acx cooler about less than 2 months ago and i was wondering if it would be worth upgrading to the gtx 880 when it comes out. i play games in 1080p at 60fps and while it is enough would it be worth selling it and paying maybe more for it when it comes out? I am very happy with the card its a huge upgrade from a gtx 650 ti and i just want to ask the community to see what i should do.
