I am not taking it personal. I genuinely didn't understand what you were asking or objecting to.

The SPU's (shaders) work in tandem in CF obviously. The lower memory is not a concern with AMD cards should the op go for a triple monitor setup. AMD frame rendering changes from AFR to 'supertiling'.( they render in 32 x 32 pixel sections of the screen, rather than alternating frames) All of the GPU's have access to the total buffer . This can be a limiting factor for Nvidia SLI setups (AFR only) but is a nice option for AMD cards.

As for the 2560 x resolution, here is a lengthy benchamark review
http://www.techpowerup.com/reviews/ATI/Radeon_HD_6870_CrossFire/1.html

I just listed the ups and downs of each scenario, but if $300 is what is available now, The 2 x 6870 is the more powerful setup.

Reading all of this new data has me thinking again.

Well i can get the 2 x 6870 now or can get 1 6970 now and another in about a month or so, so i can CF them.

If you can CF 2x 6970, that is obviously the best scenario.
...and what i listed a few posts ago

+1 for going with the HD 6970 initially (if you can) and adding the second one later. Ensures good performance for multiple monitors should you elect to go that route.

So then Ill be getting a HD 6970, a Corsair, Seasonic, Antec (TruePower), Silverstone, Enermax or Kingwin PSU instead of the Raidmax, a 1TB Samsung SpinPoint F3, and drop my 16 GB of Ram to a 8 GB set.

thx everyone

I'm using a Corsair HX850 in my AMD rig and am very satisfied with it. Also have a Corsair 1000HX in my Intel system, no problems there either.
