ATI X800 GTO/GTO2 or 6800 GS AGP?

Alright, I'm trying to get life out of my AGP system (P4 2.66/Asus P4C800 Deluxe Mobo). I'm opting for an ATI X800 GTO/GTO 2. What do everbody think about these cards compared to the 6800 GS? I was consider These X800 GTOs:

Or

I don't really know the difference between the two. I just know one has an L at the end of the number before it says X800 GTO. If I were to get a 6800 GS, I was considering this one: http://www.newegg.com/Product/Produc...82E16814130264

That model is roughly $50 more than the X800 GTO's. I can't seem to find a place that sells a decent amount of GTOs. If anyone knows, let me know. Thanks for any of the help you can give me. I was also thinking about how the 6800 GS supports SM 3.0. I wonder if that'll make a significant difference.

Cant you just stick to one thread lol, u have got 5 running in this forum alone on the same subject, and its in the wrong forum!!

lol. Sorry about that. It's just that when I put all these questions into one thread, they never get answered. It won't happen again. I didn't notice the sub-forums at the top. What's the easiest way to get them transferred?

And then a mod should close/delete this and the other thread. :p
