What would be the advantage of running a 6990 in eyefinity if it has the same vram as a 6970? Lets see some evidence of this.

No reason to prove the obvious.

So basically a 580 3gb has more actual output of vram then a 590 3gb? Considering the 590 was built for nvidia surround this makes no sense. Why would these cards base all there reasoning for existing for eyefinity/surround users when the actual ram 2gb for 6990, 1.5 for 590 is terrible. People are complaining that the upcoming rumored 680 at 2gb is terrible yet there current flagship card the 590 is only 1.5? You learn something everyday I guess.

Exactly. The 590 sucks. These dual GPU cards are no different than running 2 individual cards in CFX, only you cannot turn off the crossfire/SLI option.

RCFC89... it sucks it really does.. I actually started a thread on this a while back because I truly thought 4gb vram meant 4gb vram, but I was quickly shown the opposite to be true. This is why they are making the 6gb single gpu's but it won't come in a dual gpu/single pci slot form. frown.gif

Most people are still running 8x slots when running multiple gpu's so it won't even matter. This is why I went with the sabertooth with dual 16x 3.0
Thought this would be great for dual 7990's in the future with all there vram but obviously not.

3.0 isn't gaining any fps unfortunately either.... because these cards aren't exceeding the 16x bandwidth yet, however the 7990 might actually change that, we will see. Honestly man you will be good to go with 2 x 6gb 7970 in crossfire. That will be a very beast setup. Or hell even 2 x 7990 I mean how much resolution are we talkin?

I'm doing 5760x1200 so for now I'm going to do a 7990/7970. 7970 crossfire would be enough but for the extra 300 to get trifire 7970 performance is too hard to pass up. Thanks for your help. I'll jump up to the 6gb cards on the next generation of amd cards a year or so from now.

So am I correct in assuming you are using this formula?: Horizontal Resolution * Vertical Resolution * Color Depth = Size of bitmap = Amount of VRAM needed
Example:
A screen image in 1024 x 768 in 16 bit color is a 1.5 MB bit map. That is calculated as 1024 x 768 x 2 bytes (16 bits)
(source)

So in my case 5760 * 1200 * 32 = 221,184,000 bits = 216,000 bytes = ~211 kilobytes...

...seems to not make much sense.

Can someone else jump in on this before I hurt myself?
