Hmm... watching the videos for this it seems like I may enjoy it. $30... might sound wierd but I'm trying to pinch pennies so I can do some upgrading to my rig. Mostly in anticipation of BF3, Skyrim, Prey2, and other titles that I'd like to play with max in-game settings and preferrably some AA.
Looks tempting though. I'll have to DL the demo and give it a go.
