Let the hive mind of Engadget get that for you.
"I finally got a new laptop with a lone USB 3.0 port. I'm now looking at getting a USB 3.0 hub with a power adapter so I can use both of my USB 3.0 hard drives at faster speeds. I've read lots of horror stories where some hubs either don't come with power adapters -- and as a consequence the portable drives don't work with them properly -- or they are designed poorly which results in USB 2.0 speeds. Or, the hard drives keep getting disconnected. Do your readers have any suggestions or experience using USB 3.0 hubs? Thanks!"
A great idea, but reading post and articles about the external video card it seems that even if these are ever made it will take a very long time. there are many issues to overcome first so we shouldnt get are hopes up too high about this.these cards wont be cheap so while your waiting u might consider buying a high end pc, they are getting cheaper these days. or wait for ever :)
