have amd abandoned the word "green"?

Its not that they abandoned the word "green", just that they are trying very hard to hold on to the phrase "in business".

AMD would have to bite the bullet and license alternative 3D transistor technologies to compete with Intel's future 3D FinFET technology to have lower power usage in future CPUs. Intel owns its own research FABs to perform hi-end technology research and potentially be a patent troll. AMD gave up its FABs years ago as part of cost-cutting move.
AMD has some hope as Japanese companies Fujitsu and Suvolta have been developing competing technologies to counter Intel's 3D transistor which could revolutionize quite a few different integrated circuits other than CPUs. I wouldn't expect Intel to license its 3D green tech to AMD. It feels a little sad that the USA doesn't do much research in this area (outside of Intel); it's like Asia has most of the FABs and semiconductor manufacturing facilities. The cost of living in the USA is substantially higher, and thus the costs of everything else must be scaled up according to that. So semiconductor and instrument manufacturers that can be located in Asia will always beat out the USA on raw cost unless the buyers don't care about price.
The problem for AMD is that the japanese 3D transistor is horizontal while Intel is vertical. As with hard drives platters and skyscraper buildings, vertical replaced horizontal as the method to increase density. So, the AMD CPU made with japanese horizontal 3D transistors will always be physically bigger all other things being equal.

any news if bulldozer still sucks? after months of it being released they should've found solutions on making bulldozer work better.

I don't think Bulldozer sucks. 8 cores for $199 or less sounds interesting. It just happens to be slower and uses more power than the top of the line Intel chips. But that doesn't mean it cannot do things faster that people currently do on their home and work PCs. The way patents work, AMD may have had to use that approach because Intel has long been working upon scalable core processors up to the theoretical efficiency limit of 70 or however many that exact number is. The other thing Intel has done is put out a huge number of patents on having scalable cores handle the graphics computing and automatically make use of more cores as needed.
There's only so many innovative paths left to the second place maker when the first place holder has so many well-funded different approaches performing research and churning out patents. If the second place company doesn't keep putting more money into R&D, it may find itself blocked off in the future with a completely plugged up dead end for its currently flawed approach of pairing "RISC style" and CISC cores with a shared cache between the two as a means of gaining operating efficiency power-wise.
It's an interesting idea with potential to have the integer calculations steered to one core and the floating point operations steered to the other core, but it will also need the application to be compiled with that approach in mind. Until that happens, benchmarks and the applications will perform better for Intel than it does for Bulldozer.

^ to begin with, any people wouldn't need a rig much faster than an i3-2100 @ 125$ or an i5-2300 for 185$...
and these could run at H61 boards for like 60$...
or if you'd like a muuuuuuch cheaper quad then how about an Athlon II X4 for like 100$?
Edit: or a Phenom II X6 1055T for like 150$?
PS: theres only a handful of softwares that'll profit on all 8cores of that thing.
