£200 quid you can get a GTX 980 at that price and trust me you will never have to upgrade for atleast 5 years will run everything in ultra settings
No point in buying one of these new 1000 series cards unless your looking to run your games in 4k.
Another good option is the 780TI older series...
I like the 4k for watching youtube videos and that in but besides that graphics cards are just not capable of supporting 4k to a high enough level yet :D
