I expect the AMD A10-5800K to be a blow-out success in 3D. The F1 2010 and Shogun 2 benchmarks are both critical of not only GPU performance, but also underlying platform performance. F1 2010 sees a near 20% improvement over last-gen APUs at 1920x1080, which translates into much larger gains at lower resolutions. The AMD A10-5800k managed to pull an average of 60 FPS with medium settings and 4xAA enabled. That is, with the HD 6670. 60 FPS is a pretty respectable result for a $500 configuration. Trying the Intel 3210m in Sniper Elite V2, which uses an HD 7850m, was pretty impressive as well.
