I would suggest getting a new computer just so you can deal with Poser and other programs you use better. However, I am able to use my Dell 450 P3 with Windows 98 SE, 512 ram, Poser 4.03 with V3 well enough. I did build a P4 1.8 mhz computer with XP Pro ( don't even bother with XP home edition if you're getting a new OS ), Asus motherboard and video card, and 1 gig of ram. I'm running both of them while I slowly bring the new computer up to speed to eventually take over as my main box. The difference in how the new computer deals with even turning the figures around on the screen in Poser while your setting up your scene is like night and day. Render speeds are much faster even with the original 512 ram I had in it to start with. A faster processor and more ram definitely handles the larger files created using V3 easier than the old computer. No big shock, but I will say I can use V3 with the old computer fine, I just have to wait longer for just about everything but it's not so bad I can't deal with it. I would imagine that it's going to be rougher for you with only a 330 mhz PC but maybe not impossible. If you can't afford a new computer yet max out the ram in your old one if it's cost effective to do so, or just save up and spend the money on a new computer when you can. I was amazed how much more bang for the buck I got over my first computer 3 to 4 years back. I've got four times the computer now for one third of the price. Good Luck with your rendering endeavors however you go about it!
