USB vs Mini-PCI Express Wireless Networking

I've got an older desktop that needs a dual band upgrade and would like to know if a PCIe adapter w/ external antennas for desktop wireless is better/faster than the USB variety? They cost about the same. The router is a dual band WNDR3700 v1.

I've heard salespeople at retailers say, for desktop, go w/ the USB as they offer better performance than PCIe adapters even w/ external antennas... Does anyone know if the extra noise within the desktop case kills whatever benefits that the extra power and external antennas that a PCIe card has over a USB adapter?

Finally can anyone recommend a brand/model of USB or PCIe card to buy (under $100)?

Many thanks...
 
pcie would be better, the problem is there isn't a lot of them. i cant find one on newegg.
 
I was once told that it requires several watts to properly transmit a MIMO signal properly because a dedicated DSP is needed to process the data... In the old days 400-500mW was enough for 54Mbps, but now alot of time sensitive MIMO data processing is offloaded to the host thru drivers which can't handle the data w/ near perfect timing which causes low speeds.

I guess we can only "hope" USB 3.0 wireless adapters that had onboard DSPs gets released soon.

I guess in the mean time I may HAVE to buy a mini-PCIe to PCIe adapter, a 3x3 or 4x4 mini-PCIe card AND a set of 3-4 antennas... This is definitely going to be expensive and a BIG hassle.... Anyone with a better alternative??

Thanks...
