The only ones I see are sfp+ cards, those also require transceivers (at ~$50 per) to work. The cheapest 10gbase-t cards I can see are refurbished PCIe 16x cards with active cooling for ~$40, you probably don't want those either. Really, as a consumer you want either a PCIe x4 or ideally a PCIe 4.0x1 card, with a modern much more power-efficient chip.
SFP+ uses less power, has less latency and DAC / Twinax cables cost less then 30$ for 6 meters. The only downside is that DAC is limited to 6 meters I think.
I run sfp+ 10 gig at home. You can get SR transceivers for maybe $6ea last I made a purchase. Appropriate LC fiber patch cords are similarly dirt cheap.
