Anyone know which MIMO enabled wireless cards work with Vista x64

Well lets get straight into it. I currently have a computer up in my room which is 3 floors above my wireless router (crappy dell true mobile thing) and 2 floors above the wireless repeater (hawking technology G wireless repeater) i have linked to my router. Using my F5D8010 Belking Pre N notebook card in my desktop i have a constant connection signal of between 97-100% (im not too sure how this works, i think its something to do with having a wireless repeater and a router and that somehow working really well with MIMO technology). The problem is I just bought a new pc to replace my old one and it has Vista Home Premium 64 installed, and obviously the F5D8010 isnt compatible with that.

Does anyone know which network cards with MIMO, preferably the cheaper enhanced 802.11g ones rather than the more expensive 802.11n ones, are compatible with Vista 64 bit?

Any help whatsoever would be greatly appriciated.

Thanks
