Performance in First-Person 3D Shooters
Despite the 128-bit memory bus, the GV-NX76T256D-RH is no worse than the Radeon X1800 GTO in the “pure speed” mode and even delivers slightly higher average and minimum frame rates. And you can also see that a comfortable speed is achieved in 1600x1200 resolution. The overclocking brings about the biggest gain in 1280x1024 since the memory subsystem affects the overall performance less in this mode (as you remember, the memory chips on the GV-NX76T256D-RH were not good at overclocking).
The Gigabyte is also good in the “eye candy” mode, at least it provides a good reserve of speed in 1280x1024. At an average speed of 70fps and with occasional slowdowns to 45fps you won’t feel any discomfort in the hardest scenes. The Radeon X1800 GTO slows down less in such scenes, though.
Call of Duty 2
Call of Duty 2 is a more demanding game, so there’s no talking about playing it at an acceptable speed on a mainstream graphics card even in 1280x1024 (at the highest graphics quality settings, that is). Putting aside the practical value of the results, we can note that the Gigabyte GeForce 7600 GT is always slightly slower than the Radeon X1800 GTO in the “pure speed” mode, but is suddenly ahead at the “eye candy” setting, losing only to the much more powerful GeForce 7900 GT in high resolutions.
