Well I reformatted again last night and tried one more time with my 285. I played for about 30 minutes then ..boom... green screen with sound loop. SOB...
Installed the 260 with according drivers and I was able to play for about 2 hours with no crash before I went to bed.
EVGA has started the RMA process for me so hopefully the problem will be resolved upon receipt of the new card. From what I have read though I am a little skeptical.
