Is a 7670m with a6-440m enough for mild gaming?

Hi

I am looking to get a new laptop and need help on deciding if this CPU is enough to play games with this GPU. I've seen videos of the 7670m on Youtube but with an A10-4600m. Will there be any differences if I get the A6-440m w/ a 7670m from the A10-4600m w/ a 7670m?

Games I play are:  

Counter strike GO
Batman Arkham City
Borderlands (The First One)
Stronghold 3
Dawn of War I & II (with all Standalone Expansions)
Lord of the Rings Online MMORPG ( Played at Medium settings with I3)
Mount and Blade Warband

I play at 1366x768 and I am upgrading from an I3 with integrated graphics. Only a few games worked so I am not a heavy gamer. This is a HP DV6Z 7000.

It is priced at 513$ HP Refurbished.I know the Blu Ray player Is useless because of my screen but I can't remove it's locked specs from HP.  

AMD Dual-Core A6-4400M (3.0GHz/2.6GHz, 1MB L2 Cache)
