Ich hab mal von verschiedenen GPU's ein paar WU's zum Vergleich zusammengestellt (man sieht auch ein paar WU's die mit der CPU gerechnet wurden, netter Vergleich)...

[Fireman69]

Eine ATI Radeon HD5870/1024MB/GPU core clock: 875MHz/memory clock: 1250MHz macht etwa 2,6 Credits pro Sekunde.

DAS muß man sich ja mal geben!!! Meldung einer WU mit der GTX470.
