I just purchased a new laptop a few days ago and I should be receiving it in the coming week. It's a Sager NP5750 configured as follows: I wont be using it for heavy gaming however I might want to at some point, but I will be using it for 3d modeling. My question is, does anybody else here have the ATI Mobility X1600? From what I have read about it, it does not seem like a very powerful card. I'm thinking about trying to get my hands on a Nvidia Go7900 GS. This laptop is fully upgradable so I know its possible. If anyone has any advice or experience or just an opinion let me know, Thanks guys.
