If you want it future proof lets wait 2 months and see what / when it's coming. Nvidia isn't saying much about Pascal's availability - which usually means it's not ready just yet for production - If it was coming out soon, we would know about it,.., It wont be here for April and maybe by July we will have a release date..,If that FuryX2 was released at Christmas time, I woulda jumped on that.
No body knows at this point when any of the new generation of cards are coming out - Most of us are waiting just a few more months and lets see if the gains are worth the wait,,I think the new generation of Cards from AMD and Nvidia are going to look pretty impressive and I it would just kill me If I just spend $600 dollars on a 980ti today and in 6 months have to face the same question with the new cards,..
Again -- I am regrettably playing Fallout 4 at around 34fps and it shutters --- I'll wait even though I can have a new 980ti from Amazon here by Sunday.,.,
