I had a saphire 4890 1gb that had 850mhz core and 975mhz memory. It just recently died but it was still under saphire's two year warranty so i sent it in. They just emailed me back saying they would like to offer the vapor x 4890 as a replacement. It has 850 mhz core and 950 mhz memory. Its a tiny bit slower i guess but I was kind of hoping they would give me a 5830 instead. Do you think this is a good deal and i should just take it and run? or should i ask for better?
