your powersupply will be enough to power the machine as it came, provided you dont upgrade your video card
That makes me feel a lot better. I think the card that comes with it should be fine for photoshop work. I have been using xp on an athlon 64x2 for the last three years and I expect this new computer should be faster. So if the one I have been using can handle the work (though I know how to purge everything when it starts to slow down) I am hopeful that this new one will be faster and handle more. Thank you for the input!
