Low fps with 7970 crossfire

No, with that CPU you should absolutely not be able to get 120fps.

You are (with 99.9% certainty) majorly CPU bottlenecked on a single monitor. You need an i5-2500k/3570k or i7-2600k/3770k or better CPU to run 7970 Crossfire.

I mean i dont think it should be bottleneckin because the cpu is actually quite decent im using one of them. it sounds more like hardware probs or even the game just not working properly with that model in crossfire it happens all the time then amd release a driver and everythings fixed untilll the next one lol.
If its doing it with all your games then it sounds like bottleneckin but it shouldnt justify having to go out and but a better cpu like a i5 or i7 because amd 1100t are really good cpus aswell.

I used a 4.0 GHz 1100t with a SINGLE 7970 @ 1200/1700 and got bottlenecks in any game that couldn't use at least 4 cores well.

A pair of 7970s is going to require much more CPU horsepower at 1080p in most games.

What games are you talking about OP?

So far I have only checked my fps in bf3.

In BF3 you will not get 120fps average with 2 7970s if you have all the settings maxed out, even if you had a 5 GHz 3960X CPU.

Are your drivers up to date? You should be getting at least 60-80 average. Have you tried overclocking your CPU at all?

Its six core cpu i belive it can handle 7970 c.f
He should cheke his gpu c.f connection(low propbility)
He should insert one gpu copy the driver then insert other gpu and copy again the driver (high propbility)
Almost forgot there are mobo's that dont need the c.f gpu connection so he should try without the con if he didnt

In BF3 there's a chance the CPU won't hold him back but I dunno... it definitely can do more than 30fps

In most games, it will be a bottleneck in a big way because most games don't use anywhere near 6 cores.

Its a Phenom X6 were talking about here...
Not a Pentium 4...

Speaking of which, the real bottneck may be down to drivers, hard disk, bloated windows installation etc.
the processor should NOT be the issue, my best bet is on software issues.

Again, only in BF3. 90% of games will bottleneck, some pretty badly. Not sure you guys understand that core count beyond 2 still doesn't mean a whole lot for gaming in general...

You guys also forget that I ran a Phenom II x6 @ 4.0 GHz with a single 7970 for a few months, then changed out my CPU to the core i7-2600k. It makes a BIG difference in a lot of games with even one card, let alone two.

If you're trying to build a rig for 120 fps gaming, a K-series sandy or ivy bridge CPU is a must, unless you feel like trying to get your AMD chip up to 8 GHz or so
