So if I go for a SM951, I should go with win10, and if I decide to use win7 for a bit longer a "standard" SSD will be better?
As it looks now I think I will definatly go for the Skylake. I checked today and with everything except a new GPU and storage HDD (got plenty of music and movies and stuf like that) the price would be around £975 (which I think is pretty good).
If I would like to get a GPU for the rig, in the price range of say £250-300, which one should I choose?
