For off-the-shelf no-name WLAN cards it is in my experience often difficult to
tell which chipset is used inside. There have even been instances where
manufacturers switch the chipset to something completely different without
changing the part number!
In cases like this I tend to download and unpack the windoze driver from the
manufacturer's website. If you look through the configuration files for the
driver install (.inf, IIRC) you can generally tell which chipset is used.
Or you can buy a slightly more expensive brand name card for which you *know*
drivers exist and save yourself a lot of time.

Like winprinters. Blegh!

If I'm buying a PC or laptop I tend to go to a shop with a FreeBSD DVD or
memstick and ask if I can try booting the machine in question from it. Then
the dmesg output tells me what works and what doesn't.
Smaller shops can generally build PC's and sometimes laptops to order with
components that you specify. That is generally what I do.

Definitely agree. Never buy the latest generation hardware! You pay top dollar
(especially for CPUs) and the difference to the previous generation that is
probably better supported by FreeBSD is generally not really significant.
These days the biggest speedup for a computer is probably to use an SSD instead
of an HDD. But since GELI doesn't support TRIM yet, and I consider encryption a
must have for my own data in case of theft, I'll wait for a while. Of course
using a relatively small unencrypted SDD for the OS with an encrypted HDD for
data would be a solution for that.
