I've got a by now 4 year old Dell Inspiron 1545 with 3Gb of RAM and an Intel Pentium Core2Duo in it and runs Poser 9 fine, just as well as it does Poser 6. I'm guessing your 1 year old Dell can't be much worse then that.

Due to the childish TOS changes, I'm not allowed to link to my other products outside of Rendo anymore :(

Food for thought.....
