Since I had a few days off ive been playing, so have upgraded the monitors to 120HZ BenQ gaming versions, added another SSD, a 512gb Vertex 4, swopped the ram out for 8gb of 2133 stuff and changed the processor for a 3770K.
No doubt I will now spend the next week looking at BSOD's and HWbot screens, so for now, Call of duty calls.
