Had a stock 2009 15" MacBook Pro and running Photoshop CS5 became a chore and often plugins would crash it.
Just got the new 27" iMac, stock $1699 model. Runs Photoshop SO much faster. Made a little video: iMac output to my 46" Vizio tv via Thunderbolt MiniDisplayPort-HDMI adapter. While running Photoshop CS5, ran Topaz Adjust and Alien Skin Exposure...plugins and movie trailer ran smooth, no hiccups, def couldn't do this with my 2009 15" Macbook Pro. Yes, I know you PC guys have doing this forever lol 
made a video:
