All depends on how you look at it... The Ultra is a bit faster but the GT is cheaper and can be overclocked to the Ultra speeds. The best bang for the buck is the GT; it's almost as fast as the Ultra in some benchmarks and games. GT is for me..
Best Buy just charged my credit card for my GT; hopefully it shipps tomorrow! That would rock.
Why so much anger? Anger leads to hate, hate leads to suffering, suffering leads ot death!!!!! I think the GT uses 2.2ns and the Ultra uses 2ns, although that is not to big of a difference, otherwise their slightly lower card would be competeing with its bigger brother, lol. If you want proven technology go with X800's, but if you want same speed as ATI and more possible but uncertain technologies go with the 6800's.
I went with the BFG 6800 GT OC card and I love it! I couldn't be happier. It has seemed like forever since the mid range card actually competes with it's older brother. Last time we saw this was the TI 4400 series I think.
I got shipping confirmation to get here this morning, but the DHL driver was a lazy jackass and claimed there wasn't an apartment number on the shipping label. I'm going to bitch at him and get him fired when I prove it IS there on Monday when I do receive it.
EDIT: There are only 4 apartments where I live and there were people outside. He could have asked anyone and took 30 seconds to figure it out and deliver it. He didn't even pull in the driveway.
