just make sure you set the limit so something like 120, otherwise you risk your hardware overheating (sure it can push 300FPS on low - but its gunna run at 100% to do so)

as was said above as well, crossfire will only work in fullscreen. not windowed or borderless window mode.
I tried Fullscreen mode, no success :(

I Noticed here http://www.techpowerup.com/reviews/ASUS/HD_7970_CrossFire/19.html that The benchmark at 1080P with 7970 crossfire is 160FPS. I'm not too worried about the FPS, if it sat at 100 constantly i'd be happy. What's annoying me is that it's spiking a lot, especially when i load into a new zone.
EDIT: And ever here http://www.tomshardware.com/reviews/radeon-hd-7970-benchmark-tahiti-gcn,3104-11.html with one 7970, 104FPS and 84FPS min, The benchmark results don't seem to show the same lag spikes that mine produce. According to quite a few sites and forums, WoW does not work properly with Xfire and the gains can be slim to none, but the TPU benchmarks say otherwise. What do you think?

I think the TPU bench-marker knew what he was doing and could make crossfire work with Frogger if he wanted to. Remove one card from your system and see what happens.

have you got any other programs running, like antivirus? they could cause the lag.

so could a fragmented hard drive, or an SSD screwing up (my vertex II was terrible for stuttering)

How can i tell if that's the case? I'll try disabling my anti-virus when i next can access my PC. I've been told that another possibility is that my CPU is bottlenecking my WoW, which i don't think is a realistic idea. What do you think?

I'll try using one card next time i have acess to my PC.

Fill out your system specs please, just so we dont have to keep jumping around to see them.

Yeah sorry, Done. @ Mussels, I don't think it's my hdd or SSD, i tried installing the game on both as well as running off of an external hard drive. I will keep trying!!! :D Do you think it could be to do with my video cards having different core clocks?

i suppose something worht checking: what are your CPU temps while you're gaming?

it could be overheating and throttling, if somethings wrong with its cooling.

I'm not sure, i'll check when i can, but at 100% load when i ran a 12 hour torture test they sat around 65 and maxxed out at about 73

the problem with those tests, is they dont account for the heat of everything else (video cards, namely) when gaming.

all that heat combined *could* cause throttling, and erratic performance.

That's because CFX requires full screen. If you run windowed mode it won't run in CFX mode. Aka: It won't scale at all because it isn't working. ;)
I'm aware of that, I just didn't see good enough improvements to actually run the game in crossfire. Not worth the heat

WoW must have changed, back when I played for a short stint, I was getting over 120 FPS on a single 4870. Maybe this wasnt the populated areas, but I never remember having any performance issues. My buddy would play this on his IGP intel HD3000.

It could be your internet connection. If you're running a 56k in some online games your FPS could take a hit. In these circumstances, no amount of hardware can make up for it. What kind of latency are you getting? Make sure to stop torrents and what-not as uploading hits your bandwidth quite hard.

Also, open Task manager and visit the CPU tab make sure there is no process called "System Interrupts" popping up above 5% of CPU load. That's caused by bad drivers somewhere and your CPU having to pull double duty to make up for them.

The graphics have been updated over time. I used to play it on a Radeon 9000 Pro, now it's unplayable in some areas with a Radeon 2400 Pro.

my latest rebench on Catalyst 13.1, WOW DX11, with an unreleased dual-GPU card seems to support that.

check if turning off dx11 helps

Are the GPUs fully utilized though? I wouldn't be surprised if it was a CPU bottleneck rather than a GPU bottleneck even with the fastest of modern hardware. Blizzard games have always bottlenecked my CPU. Both SC2 and D3 can bottleneck my 3820 with my 6870s in crossfire in some scenes. It has been some time since I played WoW and maybe that has changed. Maybe I will renew for a month just to give it a try.
