It's been a while since we have reviewed a card from XFX, a company who have been producing Radeon based GPUs for many years now. They return to OC3D with a bang too, as the card we have up for review is their top line HD7950, the Black Edition, with the Double Dissipation fans.We saw in our review of the reference design card how well it overclocked, but of course we're aware than not everyone is comfortable in pushing their latest expensive purchase to the limit.If you number amongst those people then a pre-overclocked card might be just the chap for you.
