hey guys i'm in the market for a new card and I want to get pretty good performance out of my games at 1080p, bf3, tomb raider, batman arkam origins, bf4...etc right now I'm looking at the gtx 760 but I might be willing to bump it up to a 780 if i have to, is it worth it to get a 780 for 1080p? can you guys give me your recommendations for cards? thanks, also how long do you think it will be before I need to upgrade from windows 7 to 8.1 for games? I'm trying to hold off as long as possible
