Hi i've been wanting to build a new pc for sometime and i'm looking for some help with the parts i'm not sure what I really need outside, I want an i7 Processor and a GTX 1070-80 since i can have it without need to upgrade for sometime and also so it can play Virtual Reality games, any help would be greatly appreciated though I would like to avoid spending more than £1100. A further note I have an Alienware X51 R2 (I think it's R2) and if there's any parts from that I can use without compromising the quality that'd be really helpful ^_^
