Here’s another way. I sold the MacBook Pro, 8 years old because it’s hit the ceiling with OS upgrades, due to the non-upgradable processor. It’s an Intel Dual 2 Core, and I think that’s different than an Intel Dual Two Core, but it’s all water under the bridge now.
For less than what I got for the Mac, I bought an 8 yr old HP (Compaq) that was their first venture into mobile workstations, and enhanced video. It has a graphics card that is mediocre by standards, but the best I’ve used and it uses lots of power so it has a special cooling system that I subsidized with a $14 laptop cooling device from Amazon. For another $30 I got an external power source. (portable battery/USB charging system), because this baby levels it’s own battery in about 45 minutes. It has a magnesium chassis, that is probably the reason everything is still working as new. I hook up a gaming mouse and my 3d space navigator, launch SketchUp and tune out. It even has a little led courtesy light centered on top of the screen, so you can still see the keyboard in all those dark places you compute.
It has about $2k worth of software on it, corporate license so it’s supported but not upgradable. Adobe, the whole sweet suite. And now I use it exclusively for SketchUp, Chief Architect and any other business software, only. All for $240 on Craigs.
