<< Yes, that's right it will consume more battery life. However this is what you can expect. You would be best off using your laptop with the mains adapter for 3D apps. >>
Yeah, I agree, except for the part that one should expect improvements in speed to necessitate increased battery usage. Ideally, the chip should be redesigned to best conserve battery power. That's one reason why you can't just take a CPU from a desktop and stick it in a laptop.
<< I would wait to see what Dell has on offer. I still reckon Dell makes top notch laptops. >>
Yeah, I would wait too. Just a note though that with Dell, many of their laptops are not made by them. It's the no-name brand companies that actually make them, so no-name brand laptops can be just as good - it's the same hardware afterall. With Dell what you're paying for is the name, and the very good warranty and pretty good support too. Dunno about Toshiba though.
