Happy With The Radeon 7990s
Pros: The OEM cooling fans are very quiet. Even under full load they make a lot less noise than my old video cards did under air cooling. Very fast cards that can hold their own against the competition: they can handle all of my games at the highest settings (1920x1200 display) while delivering smooth play. No "slide show." Metro Last Light is beautiful with these cards in CrossFireX.
Cons: I'm running two of these in CrossFireX (4 GPUs). Several games and synthetic benchmarks are slower (frame rate wise) than one 7990 (with CrossFireX disabled). This can be the drivers and/or the applications. However, most applications and benchmarks are faster with 4 GPUs, so this isn't really much of a "con."
Other Thoughts: Overall, I am happy with these cards. They shred any task given to them. They are certainly many times faster than the old 4870x2s I replaced them with. :) I'm running them water-cooled now at 1100 MHz and they haven't hiccupped. They appears to be a lot more overclocking headroom available with water cooling. The EK water blocks I'm using are excellent BTW. I'll be upgrading the rest of my system when the Ivy Bridge-E CPUs are released this fall.
