psu: 8o+ 1200w
ram: kingston hyperX 1333mhz 8gb

crossfire 6990 speed

I would think that anything over 3 GHz would be able to keep up. You seem to be in fine shape.

4Ghz Core 2? Should be fine. Is it a quad or dual core though?
At what clock speed are the CPU bottlenecks removed for these GPU's?

which extreme one?

Given that whatever Core 2 Quad Extreme you have, running it a 4.0GHz should not bottleneck the HD 6990.

but in dual crossfire 6990 then ? lol :P

Thats why I am wondering what core 2 extreme you have.

You had better read these two articles before you think of using the 2 cards together in one rig...
Now, that would really make me think about a lot of things.....
Are the bragging rights worth the work this Quadfire setup will do on a 17'' Monitor?

Oh yeah 7970's were bottlenecked by the 3960x at low resolutions so this might be a complete waste to you if you aren't playing LARGE!
Ask a new question
HD 5970 + Q9550 CPU, bottleneck?
Bottleneck w/ Athlon II x4 630 and Crossfire HD 6850s
SLI or CROSSFIRE ?
To Crossfire or not?
Dual crossfire 6990 power consumption ?
Am I Crossfire ready?
Can I have 3 monitors on quad 6990 crossfire
