Not sure where you got that a 2*180mm monster is the same as a 5*120mm monster but if that is what your comparing then id say not simple maths says 2*180 = 360 and 5*120 = 600 plus I believe based on alphas normal branding (2*120 = 240mm) the 180 is actually 2*90 not 2* 180 so your comparing 180mm to 600mm which wont come close and while I might be wrong on that it still wont beat 5*120

Is what your asking is will a 180mm monster cool a cpu and gpu then tbh I'd say there wont be enough rad for that especially overclocked but as youve not listed what gpu and cpu im only guessing.

What case / system / budget do you have

The rad is 2*180mm not 2*90, the width is 180mm and the length is 400mm.

Here are the calculations I did:

Total fan area available on 2*180mm:
2*(90^2-30^2)*pi

(fan hubs are around 60mm diameter)

Total fan area available on 1*120mm:
(60^2-30^2)*pi

(2*180mm)/(1*120mm) => 5.333*120mm (assuming same FPI, thickness and similar performance fans)

Since Alphacool already have 80mm thick 120mm rads I made some intuitive guessing to assume that this 2*180 rad should be able handle high end hardware.

Also, here are some builds using monsta rads:

(a 2*120 rad and it seems to be able to cope with a r9 290x and a 4770k)
http://www.overclock.net/t/1295261/build-log-mini-elite-crusher-cooler-master-elite-120-advanced
(a 1*120 rad which is handling both a 670 and a 3570k @ 4GHz 1.25V)

I am considering getting a 290X and a 4770K, (for gaming and OpenCL related work) and if the builds I linked to are possible then a 2*180 should be able to handle much more.

Iv'e got no idea about the 2 x 180 Monsta but I'm currently using a 420 3 x 140 and a st30 360 ( 30mm thick ) with fans @ 5v to cool an i5 4670k ( 4.2 @ 1.015v ) and a pair of 7950's, and my cpu has never reached 45, and my gpu's sit at around the same under full load.
 
What case are you planning on putting this in, my guess is youl be able to find a case that would accept a 360 and 240 rad far easier than a twin 180. Also the 290xs are hot hot hot you will want to make sure youve got plenty rad space just to cool that, which along with unproven 180mm fans id still be tempted to go 360/420 and 240/280
 
It would be better than a 2x120 or 2x140 of the same thickness, probably on par with a 3x120 or a 3x140 of the same thickness.

For reference the Thermochill 1x160 rad (50mm) was considered about equal with standard thickness 2x120 rads back in the day.

I compared the available fan space with a 120mm rad and it appears to be equivalent to 5 80mm thick 120mm radiators

Not even close. It only has two fans, if you want to squeeze 5x120 performance from it you will need to run them at hairdryer speed.

It should yes, however fans could be an issue as you will have more noise than a comparable 120mm based solution. Even though the will be less fans they will make more noise overall as noise isn't really multiplicative (i.e two 30DB fans will make more noise than four 15DB ones would). And don't forget that although bigger fans means more airflow total at the same RPM as smaller fans, its actually lower airflow/pressure over the area (hence why 80mm fans feel like their pushing more air than higher CFM 120mm fans).
