I am new to this poser application and am very interested in this program. I am taking a CGA class at my high school and we are using new macs, which i personally don't like macs very much since i have a pc with windows xp, but i have poser 7 and i do my projects at home sometimes on my pc, but it seems like it renders very slow, like the pictures and animations and things. I just bought 2 GB DDR memory for my motherboard and it seems to run at a barely decent speed, still slower than the macs at my school. and have no graphics card, just one on my otherboard

So i was just wondering, what is or are the most important things that effect rendering time for these 3d Applications and how smooth they run? is it more of a Memory thing(which i got the max of 2 gb for my Motherboard PCI Slots) or a video or graphics card (I dont know the difference) I also use bryce and it seems really choppy and slow, so can anyone tell me what i would need to get which would speed up rendering time when i use these programs?

Thanks so much in advance
