So if I over clock the BFG 6800 GT to 400/1100 then it would perform just as good as an Ultra? If so that would rock!

Would perform the same as an ultra clocked at 400/1100 yes :)

It will perform the same as a reference 6800 Ultra which are clocked at 400/1100
I let coolbits detect optimal settings on my BFG 6800 Ultra
It set it at 444/1150

Slap on a custom cooler to the GT [We lub you Artic], add in some AS5 and you should be able to pass that.

If I run at 400/1100 will I need to add more cooling? I already have like 5 fans!

No. AS long as it runs stable and no artifacts, you wont need to add more fans. Just as a note, MY Ultra can clock to 453/1270 with no additonal fans and no water

Retail Ultras are clocked at 425/1100 (3D Mode) by default. That's the target frequency.

Not with only one molex.

How many fans do you have?

Its a standard type ATX case with the Predator alien head fascia. 2 x 80mm fans stacked ontop of eachother at the front base pulling in air(using the "alien eyes" as the grills to draw in outside air). These 2 are in front of the main harddrive bays(sata), but these are sorta blocked by the harddrives themselves so no appreciable airflow gets to the vid card. One 80mm fan on the left side case wall blowing in air, although thats not really directed at the vid card, which also uses the alien eyes grill(back part of the eye). 2 x 80mm fans stacked at the back middle of the case blowing air out, the lower most one is a bit above where the location of the vid card is, so again no real cooling help there since its expelling the warm case air, but the air coming out from here is cooler the the air the PSU is expelling, so it may help some. Obviously 2 fans on PSU itself. I also have a triple fan assembly in the third 5 1/4 drive bay. I believe these are 40 mm fans(3 side by side) and are blowing over the top most IDE hardrive...and below the 2 optical drives...I have 4 hardrives....2 satas(raid 0) and 2 IDE drives.

My PSU is also only a 420 watt with 18a on the +12.

Ive got quite alot of stuff in the case including the blue neon ligting on 3 of the visible fans.

As I can see way better than Ultra speeds on my GT, I have no desire to go for an Ultra anytime soon. 444/1210 on my GT stable, stock fan and a case without great ventilation(1 side panel fan, 1 back fan and 2 front fans that are half-way blocked from getting air, cheap fans as well). 440/1170 at greats temps.

There's someone here who's got a GT at 444 with nothing special done to it.

Probabley not going to help, hell, having too many fans can hurt airflow. But to answer your question, I doubt it, 400/1100 isn't all that extreme, not compared with some people who are reaching 430s/1200s with the GTs. I think you should be fine, just check your core temps, I consider low 80s under load to be reaching the max.

I recently tried 450/1200 on my Ultra it worked fine with no artifacts and the load temps stay in the low 70C

You can clock it that high, but from what I've seen over 435mhz the benchmarks scores start to go down instead of up as the card clock throttles during 3d games because it don't have enough power.

OK, but by time you go to all that trouble your right at the cost of the Ultra. Bottom line is if you aren't going to do anything with the GT except overclock in its stock config, then its a great deal. If your going to rip the cooler off and go with aftermarket stuff with AS, then you may as well go Ultra.

PNY Geforce 6800 GT 410/1100 seems to be stable. Im keeping my case quiet. Not much airflow. 420/1100 and FarCry gave corrupted textures after playing 30min.

yeah i thought that would become a problem. thats why the ultra has an extra molex connector. after 435mhz the card wont get enough power from the one molex.
