Let me help you with that.

Kevin, thanks for your reply. I have checked the web page you mention. I have also checked the detailed technical specification comparison by Intel but I do not have the technical background to make a decision. The research I have done to date suggests the Bluetooth versions, 2200 and 7260BN, are win8 compatible but the 6205 may not be. For me that will not be an issue at least for the foreseeable future as I am betting on win7.1 as my main system for a few years. While I am willing to spend more time doing the necessary research knowing the answers to some basic questions would be a huge help; 1) Is Bluetooth a good idea? 2) how do I decide between the 3 non-Bluetooth and the 5 WiFi+Bluetooth boards, depending on the decision regarding Bluetooth?
In this case it is important to say that either using a Wireless Card with Bluetooth or without it does not affect performance at all so I would say this depends on your needs. If your system does not have a Bluetooth module and you need one then you can get one of those but as mentioned before, the difference on these products is just the Bluetooth feature.
