If my info is right, the 7800GTX was basically designed with HDR in mind... so I don't think that's a problem.
The 1900XT looks interesting though... faster clock by almost 200mhz, and seems to have more pixel pipelines? Though it's OEM, would that give me trouble? (being a non-techie) And why is it those cards are all labeled 512 but the specs all callem 256
?
Well, anyway... by the time I can actually get one of these, the prices will (probably?) have dropped. If that's the case I just might go for an X1900XT since it just seems kinda better in terms of specs, and the OEM version at least is for a marginally (i consider 50 bucks or so marginal) larger price. Again, thanks for all the input guys.
