Sorry that's just not possible. There are gamer targeted systems that are better specs than anything apple ever made (even after market upgrades) in the sun $2k range.
I'm in the middle of producing a 17 song concept album. If I switch platforms, I have to completely redo all my mixes and learn a whole lot of new tooling. What's the cost of that? Dozens of hours of my time...
You responded to a different point.
Which is irrelevant. I don't a "gamer system". I want thin, light, excellent construction, and good battery life, great trackpad, and a good enough CPU/GPU to achieve all that.
Comparable Mac and PC systems for that cost $2000 and way up...
