Key thing to keep in mind about refurbs - SOMEBODY returned it for SOME REASON, yet it was still fully functional.
Which means:
- They changed their minds about the purchase
- User error caused them to be unhappy with it (driver problems, other system problems, etc)
- The card did not overclock at ALL
- The card had "general stability issues" - power, heat, etc - something that a quick manufacturer test to verify 'the card is working fine' wouldn't catch but will continue to be a problem for you in day-to-day-usage
Basically, if you are a tech savvy person able to diagnose problems where problems occur, they can be a good deal.
Just keep in mind that the odds of you needing to exchange it are MUCH higher than with a 'new, retail' card. Also keep in mind that you won't be getting any software, driver CDs, cables, etc - nothing but the bare card. (In this case of ATI cards, this is doubly sucky, as ATI's DVD player - even the download of it - *requires* the original driver CD to be in the drive to install it. Something you obviously won't have with a refurb.)
