OCZ are a relatively new name to graphics cards and have only recently decided to release their own, Titan, range of GeForce 2 & 3 based cards. 3D Spotlight have a taken look at the GeForce 2 Ultra version of their product line, the Titan 2 Ultra SE. Here's a snip:
Into nVidia's GeForce 2 family, the GeForce 2 Ultra is the fastest model, with official clock speeds of 250MHz for the core and 460 (DDR) MHz for the 64 MB of DDR memory. OCZ have gone one better and have increased memory speed by 20 (40 DDR) MHz for a total of 500 (DDR) MHz, setting this board apart from the competition.
