Can I run this on vanilla Cat5e or do I have to put in Cat6?

The cheap used 10Gb NICs and the switch mentioned use SFP+ ports rather than RJ45. 10GBASE-T SFP+ modules are expensive and power-hungry compared to direct-attach twinax cables or fiber + transceivers.

I had a flat CAT 6 cable and could only get 5GbE - upgraded to a normal cat 7 cable and got the 10GbE.

Cat5e usually works fine. For longer distances you will need the correct (cat6 or better) though.
