Crucial Radeon X850XT 256mb
 

As with Connect3d’s X850XT, the Crucial version easily kept the frames above 100 in the doom3 test and with details set to high. The performance gain from the overclock was good with an average of up to 20FPS increase at some resolutions, this is still an impressive feat and not to be sniffed at as it outperforms the more expensive PE version.
