Sell Wireless IBM/Atheros AR5006EX or upgrade old AR5001X+ ?

[rsramirez]

Hi all,

I have a T42p that comes w/ the 91P7301 (IBM Thinkpad 802.11abg Atheros AR5001X+ Chipset).

I have a spare Thinkpad 802.11abg 39T5578 wireless card that uses the Atheros AR5006EX chipset.

I was thinkiing about selling the latter, but wondering if its any worth to upgrade the old card.
