GTX 980 or GTX 970

[[TC-R] Sam]

Hello,

wondering what GPU you guys think I should get, my two main choices are the 980 or the 970. The 980 is £105 more, do you think it is worth it? Will be using it for playing things like GTA V, Assetto Corsa, Fallout 4 ect ect in 1080P (Not 4k).


The rest of my PC is:
Intel Core i5 4690K Haswell Processor Overclocked to up to 4.2GHz
Asus Z97-K Motherboard
8GB Corsair Vengeance Pro 2400MHz DDR3 Memory (2 x 4GB sticks)
750W PSU

Thanks!
