2 GB per process is the maximum. Most processes don't need so much, but Poser will certainly enjoy it. The OS itself runs at least about 20 processes, taking up at least 120 Mb of memory or so. Sometimes more, depends on what drivers and services you're running. Some extra RAM beyond 2 GB might be useful. That 6600GT has decent OpenGL support, no need to upgrade. At least not for P6, which does not rely heavily on OpenGL for graphics performance. Your CPU is pretty decent. A faster CPU always helps, but the system you describe should run Poser 6 just fine. You'll also want a fast harddisk. Western Digital Raptors are probably the fastest SATA drives on the market, but they're also pretty expensive. And they're not big (36 GB or 73 GB, typical SCSI disk capacities).

The pen is mightier than the sword. But if you literally want to have some impact, use a typewriter
