Another 6970 or 7970?

I know, probably beaten to death, but I get home soon and I'm itching to upgrade. My goal is to play all my games at 60 fps avg with in-game settings maxed with the standard 4xAA
or FSAA or whatever.(MSAA and all the other stuff I can do without). I use a single monitor at 1920x1080. Money isn't a issue, as if I sell my 6970, and buy a 7970 and a new power supply, it comes out to about the same as if I just bought another 6970 with a power supply ( hell, might get lucky and snag a 6970 for 250-275 ish). Only concern I have is with microstutter. Some people say its bad, some people say it's not even noticeable.. so I just want a verdict. I've never done Xfire but I always thought it would be cool to do it. It seems that the 6990 out performs the 7970 but XFire 6970's are faster than 6990s? Is that true?

You help is greatly appreciated. Thanks!
 
dual gpu cards are usually downclocked to keep heat and wattage requirements in check.

For example a 5970 has two 5870 gpus on a single board. they are clocked at 725mhz to keep it under 300watts instead of 850mhz. 6990 is probably similar in that fashion.

dual 6970 are going to be faster in any application that scales with crossfire. some games refuse to work, but the two games I have that wont work with crossfire dont need it. (world of warcraft and borderlands)

I can't comment on microstutter as i have only used crossfire briefly for benchmarking 3dmark2011. 7970 overclocks like beast and you don't need to worry about crossfire or microstutter issues. it also has more memory, which gives it better future proofing for high resolution textures. You could also probably get away without upgrading your powersupply as long as it has an 8 pin and 6 pin pci-e connector. I run my msi 7970 undervolted 1.043 at 1000mhz. runs MUCH cooler and only pulling 170 watts at full load now.
 
Micro-stutter seems to be in the eye of the beholder. Some notice it severely, others not at all. I personally have no experience with it but have read a lot about it. Crossfire 6970s should always beat a stock 7970 however an OC'd 7970 is a different story. If money is no object, sell your 6970 now before the 7800 series comes out and forces a price drop on them, pick up a 7970 non-reference (they are coming very soon, next week?) and let the OCing commence.
 
Yea, I would sell the 6970 now but I don't have access to my rig until the beginning of april :(
