Crucial X1900XTX 512 Graphics card Review @ XtremeComputing
 

while the X1900XTX is not new it still offers excellent bang for
buck. ATi released this card to beat the 7800GTX but it ended up being
stronger than the 7900GTX as well in my opinion, Let us see if it is all it
is promising or is it worth saving that extra quid/buck to get a next Gen
card.
