A CompUSA system builder I know has pretty much convinced me to switch from my long-time Intel Pentium platforms (800Mhz P-III's -motherboard limited to only 512 MB Ram) to the latest Athlon 64 and XPPro with 1.5-2 GB RAM and SATA drives. I am primarily a huge Photoshop "post-processing" type of guy and the new Photoshop CS really kicks major butt even on my current P-III's, -I like running filters on 64MB files and many work extremely well now, but some of my more exotic ones still are RAM limited. The CompUSA guy says I will flip-out when I use Photoshop CS on an Athlon 64 with a SATA drive and at least 1.5 GB RAM. So if Poser can handle it and not flip-out (and VUE 4 and DAZ Studio Beta can handle it) then I'm ready to make the jump... He also says the latest XP Pro set-up is better than my current Win2000 Pro (and that a number of new motherboards no longer even support Win2000- only XP).
