thunderbolt !!!

[sid_gupta]

is there a way to add thunderbolt interface to existing PCs??

[ico]

nope. It is useless as of now.

USB 3.0 provides enough bandwidth at the moment and Displays can always use the Display Port in graphic card.

Thunderbolt is basically a fast peripheral port combined with Display Port.

You might see PCI-express add-on cards sporting Thunderbolt soon.

Nope. Not possible. Usb 3.0 is enough bandwidth for most people till now. But yeah we may see it coming in PCI express slots soon.
