Win 7 & 10 work great with PT12 no issues... win 10 is better IMHO... I have been building computers since the early 90's FWIW... I saw where a guy was saying that all learning istitutions sell there old computers after around 5 yrs for a fraction of the price they paid for them.... look at this video, now you don't need to build a Hackintosh and the unit he is useing here is plenty enough for win 10 and PT but you really should have at least 4 gigs of ram for win 10 even thought it will run with 2gigs it slows it way down.... fist video is a hackentosh but listen to how he got the PC cheap!!!






all these are ways too build a cheap PC that will get the job done and you wont need the gaming video card....
