The same speed, that's why you run two instances so it completes two at the same time
 However, its not entirely twice as fast, little efficiency loss but it would be faster...

You will see identical performance when running 1 instance at the same Ghz as a single core a64. Like Chace said,...when you run 2 instances your first will take a small performance hit,..but overall you will complete more WU's in a shorter time.

I'll let you know once I get it all put together. Hoping to push the 4800+ close to 3.0GHz on quality air.

3.0 should be possible with a real good cooler and some top of the line paste. What are the current ambient temps you are getting inside of your case with your current system? Middle of summer can be a tough time on overclocking. 3.0 with 2 instances should crank out some really quick WU's as long as you keep an eye on what you are working on.

no, a 6800gt and 6800U both have 16 pipelines
the 6800 has 12 a 6800U will usually oc more than a gt, that's why |

ok last off topic thing
yes the only advantage is taht the ultra has a possibility of overclocking better, but its the same argument as it is with the 3700 sandiego/4000 sandiego, and 4400vs.4800 see, same thing. |

Im getting the 4800 over the 4400 becuase I dont want to HAVE to OC to have the best and when I do I have a higher multi and probably a better chip.

I think that running 4 FAH clients at the same time would be more effective than just running 2.
That's because the X2 chips have "virtual hyperthreading". I wonder what that really does. |

lol, never seen CBI screenshots of the X2 chip?
It's mostly to take advantage of software that utilizes HT but not dual cores, but i wonder what it'll do with FAH. Can't find the screenshots atm, but it's there. I saw it on Xtremesystems |

yah will intels hyperthreading is kinda wierd and stuff so it doesnt give much of a bonus
basically hyperthreading takes advantage of extra idle cycles and uses them, so im not sure how much it helps in something really proc intensive like folding. Since there are two physical proccessors on the X2, it should get more of a figure like 1.8 processors due to overhead, etc, etc |
