Doesn't really matter, both very similar. w8 will support DirectX 11.2. I've been using 8 since January and haven't missed 7 too much.
TY.
Just specced this up from local pc place, really dont want to build it myself. Needs to be mini tower for the space, but gaming capable. Low noise too. Any holes in this plan that may jump out to anyone? Price £1200
