Yep, HP has updated the specs. The pavillion series starting 799$ has a Sandy Bridge Dual core and HD6770M which is mighty impressive.
HD6770 has 480 Shaders which is based on the HD6800 barts architecture, whereas the HD6850M in HP ENVY 17(also with sandy bridge) is basically a lower clocked HD5700.
