Going from 2GB to 4GB was like bringing my over-powered, under-performing system out of its shell. There were no nagging little delays jumping through menus. Switching between tasks was no longer annoying. The network latency which was new to me in Vista all but vanished. Photoshop and Excel became useable tools again and after re-configuring the scratch disks and the paging file, Photoshop was quicker than it had ever been. I now want to grab a second kit of this memory and see how much 4x2GB will speed things up. Of course, all of this is not visible in any benchmarks, as we saw today.
