heres my sapphire horror story
i was a hd2900xt CROSSFIRE sapphire user up until a week ago, ive been a loyal ati fan for over 4 years. got the cards on release day, may 14th and one of them died 2 weeks ago, about 4 months worth of use and it took a dump, started to progressively go bad, i thought it was my monitor so i wasted all bunch of money on a new monitor to only realize it was one of the cards craping out slowly.
i had to jump through a bunch of hoops to get a RMA number, sapphire uses a 3rd party repair company to handle their RMA's, go figure. the third party company wanted a $15 check to cover, "handling" for the card on top of the shipping cost to get a defective product to them so about $25 on my end to get a defective piece of equipment replaced.
regardless, their piss poor rma procedure and just way to many ati driver issues over the years put me over the top. i ordered two 88000gtx cards and a sli mobo last week and haven't looked back. ebayed the 2900 i had here and couldnt even get $270 bucks for it, barley 4 months old!
the driver support with games is like night and day with nvidia compared to what i dealt with for ati through the years, constantly having texture/graphical problems or small glitches, just dealing with them when i didnt have to.
i would strongly discourage anyone from buying sapphire just because of their RMA policy and ati for their sheer lack of support for most games. i learned the hard way, it took me 4 years but that nvidia logo that appears while loading a game just isnt for looks.
