I own that 5950 and I must say, I have no idea why hard core gamers do not own it, it is totally awesome! Couple new things I found out about it, I emailed Sager about adding full speed fan keys like the other laptops (7700 or 9860-9890's), they emailed me back and said it has it, it was one of the FN-keys not listed in the book, turns out it was simple FN+1 for full speed fans if your into fully overclocking the machine and gaming to the extreme! The biggest news I got was notification from Sager that I could upgrade to the 7900GTX's inside the first 30 days with my laptop for only 155$...Man... I AM ALL OVER THAT!.. Juicy gaming. BTW, those bottom pictures of the 5950 would be the same with either set of video cards, they look identical, and use the same heatsinks. NO hardware midifications required.
