"Some readers may remember that my first review of a GTX460 card was pretty negative – quite simply, the 768MB version I had been sent to test was no better than my GTX275 other than the DX11 capabilities, and in fact scored lower in most benchmarks than my older gen card. However, today I am reviewing the 1GB version – and not only that, the Inno3D “OC” version which is pre-overclocked to 820MHz core, 950MHz memory and a shader clock of 1640MHz – quite a step up from standard clocks (675MHz, 900Mhz, 1350Mhz respectively)."
