7770 is better. The model mumber is normally an indicator to how good the card is within a series. So, 7770>7750.

Keep in mind that the 7770 requires a 6-pin connector, the 7750 does not.

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?

The 7770 is not a power hungry card at all, you will probably be just fine using a 4pin adapter :)

HD 7770 should be 24% faster in most applications..
