Dual Graphics 6670 or Single 7750 ?

I'm going to get a new PC, a budget gaming PC and I want to know which processor and graphics card to buy : A8-3870K & 6670 or i3 2100 & 7750.

Of course I know that the i3 beats the A8 in processing, but I'm not sure which graphics configuration is better so please help.

thx in advanced!

  1. A lot of times two cards will be better than one card , unless the one card is several levels above the two cards. The 7750 is the low end of the 7000 line that was just released by AMD so I would say that the two 6670 cards would be better. The 7750 is only two levels above the 6670.

    I never said I was thinking about 2 6670s, I said : A8-3870K APU with 6670 in Dual Gaphics mode.
  3. Your title says dual graphics 6670 or a single 7750 , To me that sounds like two 6670's. So you actually mean the intergrated graphics and the 6670? In that case it's no contest the 7750 is going to be much better.
  4. I would not use dual gpu's when a single gpu will do the job.

    Low end dual graphics cards may show up well in synthetic benchmarks, but they are more prone to microstuttering effects. Read this:

  5. the 6670+3870 will be a decent bit faster than the i3+7750.

    If you are building a PC, the FX4100 and 6850 will be around the same price as the i3+7750 but perform much better than either the 2 setups mentioned.
  6. i3 + 6850 or 6870 will be better still
  7. yes but you have to pay more
  8. I have decided to get the i3 & 7750 because I found out that if I use A8-3870K with 6670 the memory type will be DDR3 even if the 6670 memory type is GDDR5 and also because of geofelt's answer about problems in Dual Graphics mode.
    Thanks very much for the help!
