Well my pc has 160gb so space is not a problem.Also I have 512 ram and the pc's really great and fast. But still,I think 7 is better.
well i prefer cs 2 because of the following reasons can use all brushes and dont have to worry about not using them because of your version. mines works great and doesn't lag and i think it just ownz 7 .
Photoshop CS2 sucks ass because it has loads of bugs and it's so slow. I regret buying it now because it was such a waste of money. Photoshop 7.0 is much faster and reliable.
