I recently bought an BFG Tech 7950GX and noticed that its clock speeds are higher than rated on the box. It ran fine, so I decided to OC it some more to 625/1340 is the most I could push it while getting a stable picture. I have a DangerDen 7950 waterblock and it idles around 35-40. And for $600 I thought I'd atleast get it to 700/1400. . Anyone else try this card?
