What you want to do is not to compare those two monster cards in idiotic resolutions like 720p. What you should want is compare them FullHD+ and maybe perfomance per watt and perfomance per dollar.




Considering that. GTX 590:

+ Looks nicer than HD6990
+ Runs quieter than HD6990
- Runs hotter than HD6990
- Has a risk of overheating PWM area
- Has no multiple monitor indipendent desktop support
- Is more expensive than HD6990 in europe.

In my eyes HD6990 wins.
