I've been using Server 2012 as workstation after i see it was running ev[en smoother than w8 and it doesnt has some features i dislike on W8. To have an ideia, running a MKV 1080p video on my i5 450M notebook, I got 45ºc max on WS2012 and 55-65 on W8, i made many teest temps, ws2012 let my processor colder. The only problem are pixelated pics (not all, maybee 5% pictures) and sometimes a little freezings while browsing. Any tip? Thanks!
