difference would there be between two crossfired 7970 and a
5990?  Last response: in Graphics & Displays  I want to upgrade
from the 5990 I have in my machine now - to two crossfired
7970's.  Will I see that much of a difference in gaming? What
are the rumors about the 7970?  I multi monitor - 3 24" Asus
monitors in portrait mode.  2x 6970s would destroy a 5990 and 2x
7970 would destroy 2x 6970s  A 5990 is faster and slower then a
GTX 580.  To finalize my ideas, ONE 7970 would beat up a 5990
One 7970 is as fast as a 5970, so 2x 7970 would definitely beat
your 5990. But when playing only on one 24" monitor you would
not even see the difference. You might on 3 eyefinity setup
monitors, but it might not even be worth the extra money for the
upgrade. Related resources  kitsunestarwind said: Yeah one 7970
will flatten a 5970 (5990) due to the fact its way faster and
has way more memory which affects eyefinity greatly  Plus if you
add in the tessellation
