I second the recommendation of the DV6-6C53NR, due to its Radeon 7690M XT and 15.6" 1920x1080 matte display.
Ensure that, if you get the HP DV6, that you go into the BIOS and change the switchable graphics setting from DYNAMIC to FIXED. Some games will not properly engage the dedicated GPU under dynamic mode, such as Minecraft and a few others. FIXED gives you manual control over which GPU is enabled, and it should ask you to change enable the dedicated GPU when power is plugged in and disable the dedicated GPU when power is unplugged.
