Waste of money.
Very little benefit over the i5.
Its very easy to say "Oh get an i7 its a higher number so it must be better" but the fact is the i5 2500k is the processor any gamer should be getting. The i7 is a waste of money for a gaming PC.

Main changes include: added a SSD, changed GPU to a Sapphire 7950.
I'd go with ASRock for a motherboard, very reliable, Gigabyte, not so much.
You might not like the case, but its simple and very quiet, although you will need to get a better cooler if you get that case because it gets quite hot due to it being made of noise reducing material
