The new Diamond Viper V770 is a mix emotion video card. On one hand it has all the 3D features one can want. 32 megs of ram, large texture support, AGP 2 and 4 times, etc. However, on the other hand, the NVIDIA TNT2 chip this card is based on runs at only 125Mhz core and 150Mhz memory. This makes the V770 not much faster than an overclocked Viper V550. If it were not for the fact that this card could overclock so well, I would have toss it in the trash can.
