I have purchased 4 refurbished video cards from NewEgg. I had performance issues with 3 of them (1 powercolor 9600, 1 Apollo 440mx, and 1 ATI All-In-Wonder 9600XT). Fortunitally, NewEgg's cust. service worked everything out for me with only a loss in shipping fees.
The thing I want to point out here is that the last refurb. card I returned to NewEgg, the agent told me on the phone that it would go right back into the "refurbished for sale" section without NewEgg tech's evaluating the card.
So my guess is, NewEgg recycles the cards around until someone gets it and doesn't complain?
Eitherway, NewEgg has been good to me and I continue to buy from them. I only purchase the new items now and avoid the refurb section all-together.
Just my two cents...
