i cant dicide between the two and im getting an msi 6670.
so which is better for gaming
If u dont have the mobo u could get the A10-5800k and get dual graphics with the 6670
I have the CPU AMD 6300 and the GPU AMD 6770. I'm thinking about upgrading the GPU as I'm pretty satisfied with my CPU. So what I'm gonna recommend, just my personal preference, I would get the 4100 because it is unlocked and that will make it much easier for overclocking. I believe the 4100 also has a slightly higher stock speed, not necessarily clock speed but over-all calculations. Also the 4100 has a much higheefficiency because it's only 90W opposed to the 125w phenom
I don't see why you would care to buy a 6670 for the hybrid crossfire. Crossfire is largely driver and software dependent so you won't see the same boost between all your games, if any, and it's not even as fast as a single mid-range GPU like a Radeon 6870 or 7850.
This review shows that it's not worth the money but if you have a spare 6670 then it's a nice free boost.
I agree with Jeffrly completely!
