How much memory do you have now. I've only got 256MB. With that amount, you should be able to work with one Millenium figure using a high resolution texture - at least up to 3000x3000 I'd say. Since you already have XP, it's moot but Windows 2000 is as solid an OS without the frills, basically a 98 style interface. Hope you get it figured out :-)
