Thanks for the reply (and the cake, whatever that represents),
...but it would have meant a bunch more if you'd read my post first, or indeed the article above it which talks about "the only other way" ie shrinking dies. CAD programs are (so far) mostly single threaded, which is why I don't need any more cores. I don't want more efficiency, I want more power. 10 years ago that was everone's priority, but not anymore. Simply put, the less time I spend waiting for the command prompt to come back, the more money I make.
You're right, I didn't mention heat. But only because I don't really care about it. Who bases a CPU buying choice on the cooling ability? If it gets too hot, stick a bigger fan on it.
Your commiserations are also misplaced. Plenty of non-Windows CAD apps are available, and anyway I fail to see the relevance of my OS, or the need for you to put me (and millions like me) down for it. You think I give a toss about your 'real man's' operating system that statistically, nobody uses? :P
