A couple of months back, CDRinfo released a review investigating the capabilities of the XFX 7800 GT card. The 7800 GT became available after the 7800 GTX, as a more affordable solution for gamers who wanted to get all the benefits of a latest release card, but at a lower cost. In this review, we will be looking at the XFX GeForce 7800 GTX Overclocked with 256MB DDR3.
