The CPU may throttle the fsb but that will not really affect you if you are just watching videos or whatnot. And if its anything like the XPS2, the card will not achieve 3d performance level. This is because of the behavior of the XPS bios.
Back when I had a 9300 I was at a LAN party at a friends house and he "accidently" plugged is gen2 into my 90 watt adapter. After 2 + hours of BF2 the outside plastic casing began to melt. Seriously. It was soft and if you pushed on it the plastic was soft and able to change shape. We were lucky it didn't start a fire. I called Dell and told them it was malfunctioning and they sent me a new one. I only had it for like 2 weeks before that happened. So in short BE CAREFUL.
I saved my packpac from my XPS Gen 1 being I don't go mibile too often but if fit my XPS Gen 2 and current M 1710 really better then the XPS Gen 1 really snug. But theirs no way the 1730 would fit.
So thats a good reason too hang on too my M 1710 and maybe go back to desktops when my 1710 can't handel the newer games.
The price is geting crazy with the highend SLI notebooks.
I just hope laptop production will still incorperate A beast of of single Mobile GPU's rather then SLI to keep cost down a little and also keep the size of systems like the 1710 as where the 1730 is going a little bigger and heveier then I like (AND DELL WHAT ABOUT INTERNAL SOUND CARDS!!!!!!)
I mean cmon gaming without decent sound it's like eating cornflakes without the milk.
Then the fact Dell incorperated the Docking station plug with the M 90 & 1710 then screw up and take it away from the 1730.
Then on top of that the power requirements what good is a laptop that you can't even run on batery for short periods? I mean not gameing as I also use my M 1710 for work also and know that the batery life is not that great but at least it is existantwith my 1710 when I do need it for work from time to time.
Im willing to bet that the 1730 not gaming just surfing the net and basic task can not even run on batery for a hour or so if needed.
