If you dont overclock or unlock 6800GS AGP, it'll be the slowest card. If you overclock 6800GS it'll be about as fast as 6800GT = X800XL > X800Pro/X800GTO for the most part or slightly faster. If you unlock and overclock 6800GS, it'll be faster than the 6800Ultra which is about as fast as X800XT PE. So $50 extra X800XT PE means no gambling. Between GTO and 6800GS both are 12 pipes so they'll roughly be same but 6800GS has SM3.0 you want.
Thanks for the info. From what I've read so far (NewEgg reviews, posts at overclock.net), the AGP version of the X800 GTO is overclockable, but can't be unlocked. Only the PCI-e version (especially the GTO2 version) can be.
As for the 6800 GS, it seems to be about as overclockable as the GTO. But the odds of unlocking the other 4 pixel pipes are very good. So if I overclock the 6800 GS a bit and am successful at unlocking the other 4 pipes, it'll beat the overclocked but locked GTO. If the 6800 GS can't be unlocked and is only overclocked, it seems like it'll be as fast as or maybe even slightly faster than a overclocked but locked GTO. And since the 6800 GS has support for SM 3.0, HDR, etc. it's the better buy.
So it looks like the 6800 GS is the winner. As for the X800 XT PE, I think I'd rather save the $50 and use it toward the full system upgrade in a year or so. Don't think it's worth it since this will just be a hold over card until then.
Besides, my monitor's native res is 1280 x 1024 so the 6800 GS should be fine. It's not like I'll be gaming at 1600 x 1200 or whatever it is so the X800 XT PE doesn't really seem necessary in this case, right?
Guess I'll put in my order in the morning.
Thanks everyone.
