I am building new gaming pc. I cant wait right now for October 15 for AMD release.. GPU will be used with single monitor 1080p.
I want the gpu to run most of the coming next-gen games flawlessly. And i don't know with what to go.

Here is the options:
1. Buy gtx 780 and after half a year when price go down buy another one for sli.
2. Buy gtx 770 now and after AMD r9 series release, sell it and buy r9 290x
3. Buy gtx 770 and later that year buy another one for sli

Or some of your suggestions
