We start with the results coming out from Futuremark's benchmarks. These include the results of the 3DMark 05, 3DMark 06 and the 3DMark Vantage software tests.
Starting with the 3D Mark 05 benchmark, the GV-N430OC-1G scored 14253 points, which is pretty close to the result of the other GT 430 card in comparison, the Inno3D GT 430. As you can see Gigabyte's GT 430 got a higher score than the GT 220 (Gainward) but despite its overclocked GPU and shaders, it still lags behind the GT 240 series (Gainward):
The 3DMark 06 benchmark did not change the ranking among the GT 430 OC (Gigabyte), the GT 430 (Inno3D, stock) the GT 240 and the GT 220 cards. Again the GT 430 OC is having a small lead compared to the stock GT 430:
The 3DMark Vantage tests the performance of each card in different resolutions. We charted the GT 240, the Inno3D GT 430 (stock), the Gainward GT 220 and of course the Gigabyte GT 430 (GV-N430OC-1G). Again, the overclocked Gigabyte GT 430 goes side by side with the stock Inno3D GT 430. Both cards are more powerful than the GT 220 but remain slower than the GT 220 series:
