I got a gig o corsair pro (2x512, its a bit old skool tho ie it aint got the new led heatsink things), can easily run anything you throw at it, makes using photoshop a dream. On my old system photoshop ran fine with 256, and provided I wasn't running anything else like winamp etc then I could use ps and Imageready at the same time, made me feel special
yea it happened to me when i had photoshop it wouldnt let me use it so i was like man and then i deleted PS and then i was like dammit!
