Anyone see this Kickstarter to add an external graphics card to the Macbooks (or any laptop with a Thunderbolt interface)? Looks like it would fix the issues I see sometimes when using a 4k display with my Macbook Pro 13".
I decide to build my own. I agree by February or when it actually releases there will be many options. Their price is actually exactly what building your own currently costs, but the February date is just too long when I can build it this weekend.
