Since dell is offering both the 7900 gs and 7900 gtx in all 4 of thier xps1710 systems. This means that they fit the same. And if you look at the new xps 1710 it looks identical to the e1705 minus some lights and the back of lcd. Also the new xps doesnt offer gigabit ethernet just like the e1705. They also have just released a new bios for e1705 to support the 7900 gs! This makes me come to my conclusion that they are indeed the same 945 chipset. Only thing thats scary is what they are gonna charge for the monster 7900 512 ram!! Most definately it will be a drop in solution with minor bios flash to xps if even nessesary. I love dell and thier upgradeable laptops!!. Even thought the 7800 gtx isnt a huge step up from the 7800 go vanilla, the 7900 gtx 512 will be much more future proffed and overclocks like a champ I presume.
