If anyone is looking for a competetive comparison between the cards mentioned in this thread, you may find it here
The x800 Pro has 12 pipelines, and the 6800GT has 16 pipelines. You can whine about the price/performance ratio as much as you like but this information is pretty straight forward. No one made you buy ATi over nVidia, so you can blame ATi for selling an overpriced underpeforming card all you want, but either way you look at it, it was your choice, so live with it.
Honestly, it's one thing to show a bit of sympathy the first time you express disappointment in a card, but to continually spew your hatred over and over again really grows tiresome.
It's ok if you don't like ATi, but I've seen this idea spawning here lately that simply because the x800 pro sucks compared to the 6800 GT, ATi must
be downright horrid altogether.
