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?
 
Solution
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.
