I've noticed when I run Photoshop on my computer that opening other programs take a little longer and the whole system becomes sluggish. I have Winodws XP Home running on a 2.4GHz Pentium 4 with 1022MB of Kingston dual channel PC3200 RAM. I would have thought having more RAM would help this issue, but obviously not. Recently I got a new SATA hardrive (SeaGate Barracuda 250GB) and I was thinking maybe I need to get a second one to act as a Photoshop scratch disc.
