Video card opinions

Even better, you can get PCIe USB cards that have both external and internal USB 3.0 ports on them

And back to the GPU upgrade. For future reference: If you have an old PSU laying around, you could always add it to your existing system, to use in tandem. Even a small 300W unit would work fine.

See my blog on Tandem setup (Here)

Oh and btw, Antec and maybe 2~3 other companies now make PSUs with built-in ports to link 2 or more together for tandem use.
