Overall performance & Overclocking
AGP versions clocked at 500/450 have inferior performances to PCI Express equivalents, which are initially clocked at 500/500. Amongst the PCI Express boards, the Gigabyte 128D lags slightly behind. The128VP and mainly the Leadtek 6600GT Extreme are in the lead thanks to higher standard frequencies (500/560 and 550/560, respectively).
After overclocking, frequency and performance gaps are significantly reduced. Of course, as we only conducted tests on one graphic card, keep in mind that results may vary depending on the particular card you recieve.
We felt that the overclocking integrated to drivers really wasn’t that convincing for memory. With certain graphic cards, divers refused to validate some memory frequencies that worked perfectly and validated others that had graphic defects. The “test” value integrated to the NVIDIA overclocking panel and initially used by RivaTuner is then quite relative. For more accurate overclocking we advise you to use RivaTuner and deactivate this test in NVIDIA’s drivers.
