The Airlive WN-5000PCI is as good as any, when it comes to PCI based 300 Mbit/s MIMO cards. With the crowded market these days it really comes down to price, as most manufacturers offer a very similar feature set, which is usually bound by the IC used. The WN-5000PCI works extremely well and does not dissapoint at all - on the contrary it is a solid performer with excellent range and bandwidth characteristics. It can hold its own against big name players like D-Link, Netgear and Linksys, but only falls short in price, as it is on the higher end of the spectrum in this regard. That said, if you have the option of grabbing one of the WN-5000PCI for a price below 30 Euros - go right ahead, you won't be disappointed.
