I'm debating whether to get a 2nd hand 9800 pro (I missed getting a 9800 pro DDRII 256mb off hexus) or would it be better spending the extra cash on the low end of the 6800 range (~£220, pushing the boat out a bit). So basically 2nd hand 9800 or new 6800?

Any other suggestions welcome, but I'm not paying £300+ for a card so no ultra's etc.
