Can A10-6800k Crossfire with HD 4670?

i have a Sapphire HD 4670 around and i'm curious if it can crossfire with A10-6800k's Radeon HD 8670D...

processor: AMD A10-6800k
mobo: Gigabyte F2a75m-d3h
ram: Gskill Ripjaws 4GB 4gbx1 DDR3 1600 CL9
PSU: Aerocool Strike-X 500w Power Supply 80Plus Bronze
HDD: Internal WD Caviar Blue 1TB WD10EZEX Sata3

Also, can my psu support the added graphics card?

    Welcome to the Forums!

    No, you are unfortunately limited with AMD Dual Graphics to the HD 6450, HD 6570 or HD 6670.

    Really though, I would recommend completely against going this route.
    If you are in need of more gaming power, simply grab the most powerful GPU you can afford and slap it in your system.
    Your processor is Fast Enough to handle any single GPU in most all situations.
  2. oh... i see... HD 6450, HD 6570 or HD 6670 is unfortunately out of my budget.

    This is probably out of topic but i'm thinking of making my shared memory to my graphics to 2gb which is currently at 768 mb...
    Should i sell my current ram and buy 2x4GB 2133 mhz rams or just buy another 4GB1600 mhz ram?

    will memory speed make that much of a difference?
  3. Yes, with a high performance IGP (Integrated Graphics Processor), the RAM speed is very important.
    2133MHz RAM will give you a quite large performance boost over 1600MHz RAM and 8GB is still more than enough for your system.

    No need to increase the allocation to 2GB; at the most increase it to 1GB from the current 768MB.
    I highly doubt you will receive a performance boost either way, but you have enough RAM that increasing the IGP's share will not effect the rest of your system.

    If you really want to increase your performance on a budget, pick up an good aftermarket cooler and start overclocking!
    Something like a Cooler Master 212 should give you the thermal headroom to overclock the CPU portion to around 4.4-4.6GHz and the IGP to 1GHz+.
    While overclocking the CPU portion will probably not net you any increase in gaming performance, overclocking the graphics portion will give a healthy boost.
  4. OK. Will put that on my "to-buy-list".

    Thanks a lot.
  5. No problem :)
