Ok, so here's where My choices lie:
GTX 960 : R3380 ($282)

and
GTX760 : R3500 ($292)

The prices are negligibly different, but I've had people shouting at me from both sides of this argument, so I want to hear both sides from here as well!
oh, for comparison on the prices, here's an R9 270X : R2440 ($203)
((Edit) sorry, just realised that's a 270 not a 270x)

Though the R9 280x is probably closer to that performance : R3420 ($285)

No, I'm not picky about brand at all, the price is most important.
(The prices should just be a rough guide as to the difference in value between the cards here. Also, all prices have VAT included)
(Edit)
Oh, yes I'm guilty of being a bit of an Nvidia fan boy. Not a lot, just a bit. I just prefer them for no apparent reason.
(Edit)
Also found this R9 280x : R2899 ($242)
but it's refurbished...

Never had a refurbished card, not sure if I'd trust it
