Can I attach an external GPU to my MacBook Air late 2010?
Unfortunately not, your Macbook doesn't have Thunderbolt, only Mini DisplayPort. For best results, your mac should have Thunderbolt 2 to take full advantage of the speeds.



By the way, I have Macbook 2011 and I had 2x Thunderbolt displays at 2560x1440 with my integrated HD3000 512mb without a problem. But it was fast as hell when I added a SATA3 SSD with 560mbps read. Hard drives are bottlenecking! :)
