I'm a first time Builder looking to put together a PC for mostly for gaming and live streaming, but would also like it to be somewhat future proof. I've put together some parts with advice from friends but I'm slightly over budget (£1250/$2100) although I can push this if needed. Any help would be greatly appreciated, particularly looking for advice on the quality of the parts chosen and if/what needs to be changed.
Save a little money and get down nearer to your budget, by switching the CPU to a core i5 4670K. Core i7 offers little advantage over i5 for gaming and the i5 will serve you very well, especially if you overclock it.
