Techiton

AMD has just released two cards in the 7000 series geared towards entry to mid level gaming.  The Radeon HD7770 and HD7750 consume low power and deliver a good performance but the price to perfromance ratio does not deliver as seen in the reviews.

It is based on GCN (Graphics Core Next) architecture built on 28 nanometer processor technology and runs on the new PCIe 3.0 bus interface. The HD7770 is codenamed the Cape Verde XT and the HD7750 is Cape Verde Pro.

Out of the two, the HD7750 seems a better deal, it is a great entry level gaming card and good for HTPC setups as it does not require a high power supply.
