  1. Best answer
    7770 is better. The model mumber is normally an indicator to how good the card is within a series. So, 7770>7750.
  2. hd 7770 will be better in every way.
  3. Thanks a lot guys.
  4. Keep in mind that the 7770 requires a 6-pin connector, the 7750 does not.

    I am not very knowledgeable about these things. I have just placed an order for the following components. Please let me know if this card is compatible with these components.

    1. Processor - Intel 3.4 GHz LGA 1150 4670K i5 4th Generation Processor(https://www.google.co.in/url?sa=t&rct=j&q=&esrc=s&sourc...)

    2. Motherboard - Asus Z87-A Motherboard(https://www.google.co.in/url?sa=t&rct=j&q=&esrc=s&sourc...)

    3. HDD - Seagate Barracuda 1 TB Desktop Internal Hard Drive

    4. RAM - Corsair Vengeance DDR3 8 GB (1 x 8 GB) PC RAM (CMZ8GX3M1A1600C10) (http://www.corsair.com/en/vengeance-8gb-ddr3-memory-kit...)
  6. Yes it should be fine as long as your power supply has a 6-pin connector on it like this: http://techreport.com/r.x/psus-0907/pcie-connectors.jpg

    Thanks but my power supply does not have six pin connectors. They are all 4 pins. Is there a way to use converters?

    Moreover my SMPS is 450 watt. Is this whole configuration okay with it or I have to increase the wattage of the SMPS?
  8. The 7770 is not a power hungry card at all, you will probably be just fine using a 4pin adapter :)
  9. HD 7770 should be 24% faster in most applications..
