Thanks for the help guys Stryker which version of win 7 would you suggest as I am not a fan of win 8 either. I am looking at spending between the £800-£1k price maybe a bit more for a whole new build but I was going to replace the Gpu last and not for another month or so.
How much better would something like this be

Cpu: http://www.amazon.co.uk/Intel-Graphi...+Core+i7+4770K

Mobo: http://www.amazon.co.uk/Z87-PRO-Moth...omputers_img_z

Ram: http://www.amazon.co.uk/Corsair-CML1...omputers_img_y

SSD: http://www.amazon.co.uk/Samsung-Seri...ords=ssd+drive

I already have a case given to me from a friend its a Cooler Master HAF X Usb 3.0 XL ATX Case.
