New PC 2015 Build

Get an i3 4170 instead, it's slightly cheaper and better.
Save money on Windows, get a product key from eBay, they're about £15 and you can download windows itself from their site, to be installed as an ISO from a USB where you enter the digital key that they send you (eBay).
With the money you save there, get a 950. The 750 Ti is good, but old.
Also save about £10 and get an EVGA 500W PSU, the cheap corsair PSU's aren't very good at all. If you're unsure, google it and add "jonnyguru" at the end for the ratings.
 
I very much enjoyed your response MAttz and Although i agree with the I3 4170 instead and the new Powersupply that is as far i have gone. The GTX 750ti is a stepping stone so to say. I may upgrade to the gtx 960 and grab an i5 once the prices become more comfortable. The Operating system i am keeping as a product brought from Aria PC only because I have had bad experiences with Ebay. But I do thank you for you're input and i have made some changes.
