Jim, I run Poser5 on a IBM T41 laptop at those times when my PC is otherwised engaged (Kids killing stuff etc). Off the top of my head the spec is a P4Mobile with 512mb Memory and 32mb shared video memory using ATI Mobility (7500 I think) chipset. I have to say the Poser is only marginally useable especially when I have multiple figures. I've yet to try Poser6 but hopefully the OpenGL support should speed things up a bit, as Cinema4d runs ok. My main issues with using a laptop for 3D work as the limited screen resolution (1024x768 normally) and having to use a touchpad or trackpoint rather than a mouse when I'm working with the laptop on my lap rather than at a desk. Shared memory indicated that the video chipset (GPU) will use some of the system memory, ie you have 512mb of physical memory installed, and you allocate 32mb of memory to the GPU (Some laptops allow you to specify the amount in the BIOS) you will then have 480mb availiable for Windows. Dedicated memory is memory that is seperate from the system memory and is useally fixed by the laptop manufacturer, but does tend to be faster than using shared memory. Is there a reason why you want to use a laptop rather than a desktop? $1300 would buy a decent spec desktop PC (Probably better than an equivelent laptop, but I'm in the UK and don't know how US prices compare).
