I need some help picking out a PC laptop for work. I haven't really been looking at PC hardware recently, because I love my Macs too much. So I'd really appreciate it if the MR community could help me out. I will be using this laptop for 3D CAD (Solidworks specifically). A few questions about buying: 1) Vista or XP? I like XP just fine but worry that I would have to shell out later for Vista because of Vista-only future software or features. 2) My boss recommended I price out a Dell laptop. I'd like some pointers to good deals, keeping the intended purpose of the laptop in mind. 3) Any CAD experts: should I go for the OpenGL cards? Or would the gaming cards be good enough? I've heard horror stories about graphical glitches and cards even crashing Solidworks. How would I justify the expense if I were to go for one? 4) I'd like to hear about the systems other people here use and their personal experience with them.
