Should I add my site name to the title?

[irock]

I was wondering if I should use this title (a) rather than this one (b).

(a) <title>Logitech MX700 Cordless Optical - Input Devices - PC Arena</title>

(b) <title>Logitech MX700 Cordless Optical</title>

Will adding category name and site name affect keyword density?

MX700 is under Input Devices of PC Arena...

Thanks.

There is a discussion going on now on this topic here [webmasterworld.com]

In the Google Update thread I saw a post from Googleguy to say that Google doesnt pay that much attention to keyword density.

Of course this is only Google and doesn't count for the rest of the SE's
