Question Crossfire amd 6970 with 6850?

i am going to be purchasing an msi lightning series amd 6970 graphics card with 2gb ram, my current graphics card is a gigabyte 6850 with 1gb v ram. i was wondering if these 2 would make a good crossfire or if crossfire has to be the same gpu to link to another. i would assume they both link up because they r both 6000 series.

second question i have a cooler master 700w silent pro modular power supply. would this be enough power to run both of these cards at the same time?
motherboard is an asus maximus gene-z 1155 micro atx intel motherboard

You can only crossfire cards in the same subseries (IE 6970-6950) so no you can't crossfire a 6850 anda 6970

700 watts is a bit shy of what you would want to crossfire a 6970 (if you could link it with a 6850). I would recommend the corsiar AX 850 or higher for doing a crossfire setup, just to make sure you're not running the PSU too hot and heavy.

Sorry its not possible, the 6850 would be able to crossfire with a 6870, or the 6970 with a 6950 but you cannot otherwise.

Cool a let down for crossfire but opinion needed for my old build

ok thanks guys. i have been in the computer building for quite a while now but have never done crossfire, and i figure with buying a new gpu and having one already i would have loved to see the numbers. but ill settle for the beefy 6970 that i am getting. is going to be $390 well spent i think.
as long as i got a few replies how much you think i could get for my old build>
old build specs:
asus p5g41m-le motherboard
intel core 2 quad 2.5ghz stock clock OC currently to 2.9ghz
4gb ddr2 1066 ram
2tb wd hdd
64gb sata II ssd
gigabyte ati 6850 gpu
600w ocz psu
case modded apex case to correspond directly to the aftermarket cpu cooler,
cpu cooler arctic cooling freezer 7 pro
2x dvd burner (1x lg dual layer capable, 1x single layer asus dvd burner)
add on pci express sata card 2x internal sata or 2x esata. (not capable of using all 4 at once)

ive put a lot of work into this build including custom leds with toggle switches built into front bezel and
a custom side panel window with custom fan grills.
as well as 2 80mm fans customized into the bottom of the case to draw air directly to the gpu from outside of the case.
