Im not sure of the Mac's spec, but it was the cheapest. It is irkesome you cant add more RAM as that would probably help. Ive never really been comfortable with iOS so am happy to go back to Windows - i think it comes with 10. Mac dont make middle ground desktops - its either mac mini or £3k, unless you want one built into a monitor - and as my set up runs through an AV amp and 50" of 4k awesomeness, ill live without. Hey ho, i look forward to the new toy i7 6700k, 4.4ghz, 16gb 2133, amd radeon r9 370 with 4gb gddr5, some liquid cooling and a crazy glowing alien head. No idea whats the spec means, but hopefully itll be better than the mac. Kinda getting to the point where im wondering what to do next in KSP? I know theres loads to do after getting to all the planets, just not sure what!
