I went to this>
http://www.backcountrybowhunting.com/articles/tools.php and typed in everything and it says you'll be at 298fps and 79lbs ke with a 400gr arrow and 29" and 60lbs. Sounds like a deer killin machine to me. And i have to say i shot most of the pse and the gx was the only one i liked, its a sweet bow for sure.
