Crucial Radeon X800 PRO 256MB
 

It's safe to say that any card, and I mean any card, based on the
R420 GPU will be a good one. Greater rendering parallelism and higher
core and memory speeds ensure that benchmark performance will be
stellar. That point of view is corroborated by decent benchmark results
from Crucial's X800 PRO. If, then, all X800 PROs are considered to be
'good', what makes one better than another?. What immediately springs to
mind are cards that arrive pre-clocked at higher-than-default levels, or
ones that bundle in the very latest games, or, for most buyers, the ones
that are the cheapest.
