nVidia card manufacturer recommendations

[Arthur Chance]

Somewhere, possibly here, a while back I saw a remark that certain 
manufacturer's nVidia cards worked reliably with the nVidia supplied 
drivers and others usually have problems because they tweak nVidia's 
reference spec. Of course, I didn't bookmark it and neither Google nor 
searching the last years' worth of the freebsd-questions@ archives has 
turned it up.

Can anyone recommend which manufacturers I should look at and/or which I 
should avoid? I'm specifically looking at the low end GT520.
