i have to say..this is HORRIBLE..its just neck to neck with the 6990..plus the card can't dive into OCing..well we will just have to see it more as drivers mature..but at launch it was epic..poof!!

This is why people should not assume things. I remember reading more than one post where people were saying that this card was going to beat the HD6990 by 25% at least.

My... that's the usual non-sense talk ... you should be used to it by now

I wasn't talking about air cooling, but to sum up the air cooled facts...

The 6990 will go to about 950MHz on air before you have to go crazy with the fan... but the VRMs seem solid (I think it is only 8+2 but maybe they are just better quality?). Most sites are reporting 675MHz-750MHz on air for the 590. Any higher and you risk hitting the OCP limit. Fermi draws A LOT OF POWER. At those clocks you will have a little more power with the 6990 especailly at huge resolutions, but it will be loud. The 590 is slightly slower but quieter... This the air cooled conclusion -- and I think we all understand this point by now.


If you put both cards under water 1) 6990 fan noise is not problem 2) you may run into issues if you overvolt too much on the 590 -- you will either hit the OCP limit (450W) or blow the card if the limiter is disabled. Nvidia has acknowledged this themselves.

Basically, somebody needs to put out a good non-ref power design to really unlock the 590 clocking potential (under water) whereas the 6990 power design seems fine even for extreme clocking (again I am not talking about air cooled here)

Saulin is a nvidia fanboy. Half his information has no backing.

The 590 has very poor phase regulators. It starts to crack when it reaches 580 speeds.

^point to be noted...u r saying 6990 is not a good overclocker but it reached 1ghz nd above that u have to increase the fan speed.....

so how's 6990 is not a good overclocker?! it reaches 1ghz and above but* fan has to be on 100%......but the noise it creates is better by miles away compared to GTX590's low clocks,low OC capability and a card that have tedency of burnout....

u r buying a 700$ card that have these issues......AMD must be laughing looking at this nd thinking we have a winner in hands...

Performing overclocking the GTX 590 can only be described as a big pain in the ass. I've never seen a more crash-happy card than this when doing overclocking. Basically my "find maximum overclock" consisted of setting a clock speed, running a benchmark for 10 seconds and then waiting 45 seconds until the system finished rebooting after a system hang. If you plan to do overclocking, please make a system image backup, so you can recover quickly in case the constant system crashes break something.
How can they possibly say this so early in time? It just released and drivers havnt had any chance to mature at all.

Shouldn't matter, every new card released had beta drivers 5xxx series 6xxx series, nvidias 4xx and 5xx ect.... They all showed their overclocking abilities off the bat. Drivers improved performance, not constant and daunting instabilities.
