to play future games mean you need a pretty high end gpu that is available now. gtx980 will cost you $730aud at msy alone. 970 might not be that future proof, unless you are will to sacrifice gaming experience (lower texture quality) in the future.
With 1000aud, most likely you will be getting a gtx970 or similar from amd side, a decent powerful psu will set u back about $150 and a i5 will set u back about 200to 250 again, and this doesnt include ram and ssd+harddrives and case.
