Okely dokely . Currently if I was doing a Skylake build I'd be contemplating:- i5 6600K (~£200) Asus Maximus VIII Ranger (~£145) DDR4 ~2400MHz+ (probably 16GB, 8GB be ample though but as currently ebuyer have HyperX Fury 2400MHz 16GB kit £57 I'd get that) If going 4K now and I would like FPS of min ~60 I'd opt SLI 980 Ti, as review data state total system usage with them OC'd = 652W coupled with an i7-5960X@stock on X99 platform, I'd think a good 850W PSU be ample, worst case look for 1000W on promo. Why the Fury X hasn't come into the equation is I'd probably wanna replace the stock AIO cooling for custom loop due to:- a) rad is 12 cm wide, and 15.5 cm tall so I reckon I may run into an issue of mounting 2x those on same surface close together. b) may not like 2 sets of pipework around case. By going 980 Ti I reckon I could still be on air (save some £££ vs CL with Fury X CF), with good airflow in case I'd think temps/noise not be an issue. CPU again probably air cooler and not custom/AIO water solution, probably aim to get an Archon SB-E X2 2nd hand (which I did for my i5 4690K rig ~£13.50). Excluding PSU and other bits I reckon that's about £1400, what is budget? Also I reckon that's the end of getting gold bullion but maybe differing set of questions from SWMBO .
