Is there a PCI Express 2.0 or 3.0 x16 to USB converter that will fit and run a Radeon HD 7870 Graphics card to connect to a Laptop?

AFAIK a USB port doesn't have the required bandwidth etc to run a card like that.

How about a something a bit smaller like the Radeon HD 7770 would that work?

Nope.
The 5Gb/s that a USB3 port can handle is nowhere near enough for a graphics card, for a graphics card you want a PCIe Gen2 8x slot which is about 4GB/s of bandwidth (note that 5Gb = 0.625GB).

If you want to run an external graphics card, the only viable solution right now is either a low performance card connected via Mini-PCIe or Thunderbolt-PCIe enclosure.
