It wouldn't be a huge difference with a 1090T under the hood. A highly OC'd 2500k/2600k with three 6970s would be lethal for sure.

1090T wouldn't do much more IMO

But if you add another 6970 its almost perfect scaling in most games, so I would expect a 6990 to do around about 2.5x more FPS if you added it to your 6970

6990+6970 is just like 3X 6970. No differences. So yes 6990+6970 will be much better then 2X 6970 Crossfire.

But your CPU will bottleneck that crazy fast Tri-Fire set-up. Can't you exchange that for an i7 2500K?

Yeah and even OC'd to 930Mhz everything stays stable.

Hey, which PowerColor 6970 bios do you have? I noticed my Sapphire 6970 is just like your XFX 6970, 950/1450 capped.

At 3x 1080p, the video cards will be doing all the work, so that 1090T will not bottleneck you much at all.

one thing I noticed with the new drivers it gives more accurate reading of the gpu temps, or uses the two gpus more efficiently (balanced) so that they work at closer temps. before my temps were like 48/42 under load, now they are within 1-2 degrees of each other.

nice! now watercool it!



does anyone know why when playing GTA IV I get about 2 frames per second when I swing the camera around?

my 6990 is @ 930/1350 so it should handle it fine and I have all the latest catalyst profiles installed. and official 11.4 driver. running eyefinity too.

Do you want me to send you my modified Powercolor BIOS with VID 4 at 1.25v and CCC limits at 1500/2000? If yes, send me a PM, and your e-mail, and I will sent it to you.

Or just tell me the voltage you want and I will send you the proper BIOS.

And jummies. Welcome to the Club!
