Well I didn't read up... but to interject, I noticed that the 7800 is really cleaning up in the high resolution benchmarks in general. That is where it's performance advantage seems to be the greatest over the 6800.
Also, I really don't think the increase in price is very outlandish when you compare the price/performance ratio of each card. Now whether or not you will need that extra performance and therefore whether or not it would be wise to pay for it is another story.
Yes, but no sprinkles. For every sprinkle i find, i shall KILL you.
