Help Request: Two 2GB 5870s vs Two 6970s

post #1 of 4
Thread Starter 
Hello all,

I have a pair of the following video cards in my system, driving three monitors at 5760x1080 (Bezel Compensated Resolution).

ASUS RoG Matrix Platinum

Would I gain significantly higher or smoother performance switching to a pair of 6970s? I know that the 6970s are better then the 1GB 5870s, but how do they compare to the 2GB models? Especially for Eyefinity?

I was thinking of a pair of these for 6970s:

ASUS Direct CUII 6970

Finally, as a bonus question, if anyone has the answer, would it be better to pick up another one of the 5870s I am using, and Trifire them? I can still get a Matrix Platinum in the near future if need be (not off Newegg mind you...they deactivate all the good cards way too quickly).

That Asus card is a 3 slot card, not sure if you wanna Xfire that.

2x 6970 would definitely give you a nice performance bump. I'm not actually sure if 5870 trifire will be worth it. You might gain the performance of 2x 6970, but then you'll have to deal with 3 cards.

My board (the Crosshair IV Formula) has the correct slot spacing for it. So it's definitely doable.

I just want to figure out the upgrade path I should go for. Until Bulldozer is out, I won't be upgrading my CPU, so my focus is on other elements of my build for the time being.
