Decided to start a fresh thread about this.
Budget: Around £1000. This is for the whole system: Case, PSU, Monitor, etc. (doesn't include mouse and keyboard). 120Hz+ and 1920x1200 would be nice, not too concerned about actual size, it's not going in the sitting room, but on my desk. ~£200-£300 or so.
Looking at an i5-3570K (K isn't entirely necessary however).
Probably looking at a Z77 mobo, no idea really about what features I need though (something like this?).
Ram: 8Gb+.
GFX: Something like a GTX 760/770.
Will be buying in early Feb, so got about five weeks to sort out what I want.
