i went on newegg to look at the 8800 gts 512mb g92 by EVGA and saw 2 of them. so i deiced to compare them. after i compared them both and they looked the same but 1 is $50 more and comes with crysis with a $50 difference between the 2 cards. so i was wondering, does the $339 one charge $50 for crysis and isnt vistas certified but has a lifetime warranty OR the cheaper one is vistas certified but doesnt come with a lifetime warranty and crysis.

All EVGA cards have a life times warranty, the cheap one has Vista certified drivers as its exactly the same card as the more expensive one.  The fact that is says otherwise is just a typo.
