Hello, I am not big on computer requirements. I read that Poser5 will probably need quite a bit of computer power. Alas, I have a older model Dell, (two years old) It is 1 gig speed, 256 ram and Pentium three. Checking the upgrade site at Dell, it seems the only real important I can upgrade to is 512 ram. I can go to 80 storage but I have 60 and have only used about 18. Do you think it would be wise to go to 512 ram or will the 256 work. I don't think it would be hard to put the other chip in there but with me anything is a adventure. Thanks, Bill Conn
