external gpu

hey i was looking to find some sought of external gpu that could plug into a laptop, i have usb3.0, this topic is very scarce on the net but asus make a product that acts as an external gpu, big and bulky, but its just for home so i can play some games, and use it for more complex cad files at home, plugging into a bigger screen.

Does anyone know much about this topic or had expirience with an external gpu?

Does anyone also know of any other external gpus other than the asus one and does anybody think this will actually work well?

 

See the eGPU PCIe 2.0, Thunderbolt, USB 3.0 update in http://forum.notebookreview.com/7575216-post4031.html . There's details of upcoming USB 3.0 DIY eGPU hardware. If you don't have an expresscard slot then consider a mPCIe implementation. You'd be replacing your internal wifi with a PM3N board to get pci-e bus access.

 

I'm still waiting for that to happen.... usb3.0, pci-e 2.0 and thunderbolt will be a game changer =)
the current implementations are still very crippled with huge bottlenecks.
I hope we can see x2 usb3.0 or x1 usb3.0 + expresscard 2.0 egpu's...
or thunderbolt hopping it's implemented in future notebooks... sony vaio z isn't exactly a bargain...

yes sony's solution is not a feasable solution,

its a bumba that intels ivy bridge will not support thunderbolt, it will be up to the manufactures to integrate this, and as seen with usb3.0 computer manufacturers will take there time to do this.

will usb 3.0 be fast enough to support external gpu's i mean its only half of what thunderbolt will support at 5gb/s compared to 10gb/s

do you think that we will see many computer manufactuers implementing thunderbolt next year?
