Hi, I'm considering purchasing the C90 from Gentech computers. I have a few questions about the system :
1. Is the graphics card an 8600 GT or plain vanilla 8600?
2. What does it mean by saying "upgradeable video card?" Does that mean I'll be able to easily swap it with a more powerful card once it comes out? (8800m gtx?

)
3. Should I opt for the c90 or the one that uses santa rosa? The instant single core overclock sounds great for games. I guess I should just hope that more games would start using both cores.
4. My needs - I'll be using it for college work a lot, programming, 3d modeling and animation (a lot of rendering) and of course, I'm an extreme gamer. The last part brings me to my concern : overall, a lot of people don't seem to be impressed by the 8600 cards, and some claim that the perfomance is only on par with the 7900 gs.
Is it reasonable to expect the perfomance to at least match that of the 7950 gt
in the near future, once better drivers come out? Or is it only useful for playing DX-10 only games at the lowest settings?
Obviously it's foolish to expect the battery charge to last more than an hour on this one, since I'm going to do quite a lot of heavy work on it most of the time, but it'd be nice if it lasts a little more on the occasional light loads (like web browsing). I'd also love to know how much difference a 9-cell battery would make. I'm eagerly awaiting the battery test review (a full review would be awesome

).
