Still a potent high end Gaming Card.

As a rule, if you plan to play modern games comfortable, to need to ignore any graphics card below the following: ATI 3870X2 (3000 series) ATI 4770 (4000 series) ATI 5750 (5000 series).

This card easily out performs ((25-40% more flops in games) then new 5770's and 5750's, which makes it a potent beast for your PC. The cards use HDT from CPU coolers - liquid vaporisation in heat pipes to achieve improved cooling.

The card fan spins up around 1500-1600rpm, which means you will be able to hear it.
The Tdelta at idle (net heat after subtraction of room heat) is 30C in cases with moderate cooling fans.

Under full load the Tdelta reaches 53C and fan speed reaches about 2300-2700rpm (fan max speed is about 4200rpm).

This GPU differs from the 512mb version by having a GPU with a higher thermal specification (can operate at higher temperatures) and also a quieter fan.

As a rule: buying a factory OC edition will normally get you quieter unit, either from having a cherry picked low temperature GPU (all processors are not created equal) or better fan and heatsink.
