When the **** did Newegg put the 6800GT down under 200 bucks! Go for the 6800GT for God sakes!

The GT is hands down the best out of the three without even looking at prices. Now I'd get the 256MB version, but that's just me.

I Know the 6800gt is the better buy however, It wouldnt be in my best intrest...Im going to be building or purchasing a new machine(PCI-E) early next year. My current setup uses AGP.

None of those linked are the 6800GT. They are 6800s and one is 6600GT.
