whats there to 'wow' about?
I doubt this card outperforms the 128mb version by much and considering that you could get a non-pro 9700 for about $230 which would easily out-perform it, the 5600 is too little too late. Even a 9500 pro ($175) outperforms it for the most part, and most 9500 pros can be mod'ed to 9700 levels.
Nvidia is clearly the loser this time about, no point in buying any of their cards for the most part.
