Cool thanks I'll stick to a lower priced one then. Hmm pretty similar, GTX seems to win on strategy games which is the most important for me so I'll roll with that.
Now just the case left to choose: I was going off this article http://www.tomshardware.co.uk/antec-gx700-cooler-master-storm-scout-2-advanced-in-win-gt1,review-32724-10.html.
The Antec GX700 had the best value v performance but I didn't really like the look while the one I picked Ostrog GT got the best value overall pick.
On that motherboard, it's pretty much the cheapest H87 on pcpartpicker ATX form factor. Not sure what difference different H87 models would make.
Big thanks for all your help by the way!
