To be fair a GTX970 is only 50 quid away from his budget, so it's not an entirely unreasonable suggestion. I agree with the idea of a well-rounded rig, but we can't really comment on that because he didn't share his other specs (which he should when asking advice like this). Anyways, another suggestion would be to wait for the inevitable price cuts on other nvidia cards and of course from AMD's side (I think they already did a few?) but right now the GTX970 is such a ridiculously good bang-for-buck card that it makes majority of other purchases a waste of money at this time. You get essentially the 3rd best commercial graphics card in the world for 360 dollaroos - really hard to beat that.
