Wow, what an enormous price disparity between P4000 & P5000 for the Precision 7720. Under $200 for used P4000 up to $1,200 & only available overseas for P5000. Dang. So P5000 is that good, huh? I've seen various posters state that you shouldn't buy used models of these cards. Just regular buyer beware on used stuff, or is there a specific reason to steer clear of used P4000/P5000?
In addition, I thought this thread was mainly about the graphics cards for Dell Precision 7720's & similar. But I see folks mentioning graphics cards that I can only find for PC's/towers/full-size form factor boxes. For example, is there some version of a GTX 1070 made for a notebook? All I can find is this guy doing a GTX 1070 card...no clue where he got it from...on a Precision 7710, but sounds like some light modding is needed...
