I'd rather not..
My desktop is getting on for 3+ years old but I doubt I could get the warm feeling of 5ghz out of newer hardware without paying silly money. Besides, my kits been running the beta win 10 plus a couple of severs and win 8 host without any issue what so ever (though the ssd does make a difference) now my laptop that's getting replaced soon... I've had enough of the damn thing being slow on 8 but it is 9 years old...
