I currently run
2x MSI R6850 Cyclone PE/OC Radeon HD 6850 1GB 256-bit GDDR5 PCI Express 2.1 x16 HDCP Ready CrossFireX Support
in crossfirex I was looking into buy
1 or 2 HIS IceQ H787Q2G2M Radeon HD 7870 GHz Edition 2GB 256-bit GDDR5 PCI Express 3.0 x16 HDCP Ready CrossFireX Support Video Card
I was wondering if I should
a) even bother
b) buy one set it up in 3x crossfirex
c)buy 2 and set it up in 3x crossfirex
d) save my money
I use my computer for mostly gaming and am looking at purchasing a pair of 2560x1600 30" monitors.

Best solution

Still, you should go with the dual 7870s. They should actually be more powerful than triple 6850s and they have more VRAM for when you are able to use that second monitor. It's a win-win situation if you ask me :D

This is simpe HD 7870's.

I want to clarify this.

HD7850/7770 is the direct price point to performance replacement of the 6850.

HD 7850 is the direct performance replacement to the 6950/6970.

In context the 7870 and up are well ahead of anything AMD offered with VLIW4.

I would even consider going with CFX 7850's

Now would you reccommend me going triple crossfirex and leaving one 6850 in my rig? Or should I be a gentleman and a scholar and donate both of them to one of my friend?
What kind of performance would be gained by leaving a 6850, I know two way crossfirex is like 50% isn't 3 way something like 30%?

I appreciate all the reccomendations guys, you rock!

I don't think you can CF a 6850 with a 7870, if that's what you mean. You could CF 6850 with a 6870 and a 6950 with a 6970, but I don't know if it works that way between generations. And if you just leave it there, it won't provide any boost to performance.
