Do'nt even think of not trying to get used to P5, you'll regret it someday. It renders nicer, and has many new techniques. Do'nt lissen to these posts. The only thing that makes a differance in render times is your CPU. My Main machine only has 256 and I was fine. In fact it is down right now and I've been doing fine with a celeron 400, 64Mbs or RAM, and a 1 GB Virtual Memory allocation. Look into your version of windows for this feature! If you are interested in more RAM though, be sure to check out pricewatch.com on your way over to E-Bay.com. If you can use SDRAM 512MBs is like $30!
