Laptop APU upgrade(Asus K53Z)

[Cr3a7eR]

I have Asus K53Z with AMD A4-Series A4-3305M
http://www.cpu-world.com/CPUs/K10/AMD-A4-Series%20A4-3305M.html

Can I replace it with one of those APU's
And Do I need diffrent BIOS?

1.AMD A10-Series A10-4600M
http://www.cpu-world.com/CPUs/Bulldozer/AMD-A10-Series%20A10-4600M.html
Which is Socket FS1 (FS1r2).Is it diffrent from FS1?
And Microarchitecture is Bulldozer, not K10?
or

2.AMD A8-Series A8-3550MX
http://www.cpu-world.com/CPUs/K10/AMD-A8-Series%20A8-3550MX.html
it has the same socket but diffrent TDP 45W

I doubt that the A10-4600M will work. Even though Trinity and Llano mobile processors use the same chipset, there are some differences in the socket that make them incompatible. I've heard that some people tried to run Trinity processors in FS1 (not FS1r2) motherboards, and that didn't work.

Your second choice should work. The CPU has the same stepping, so in my opinion you won't even need to update the BIOS. It may run hotter under load.

I was wondering about that "Dual Graphics".
Is there way to upgrade APU with A8 and Dual Graphics?
I am not sure how Dual Graphics works and do I need free PCI(e) slot ?
Like this model who has the same Chipset but Dualg Graphics

Dual graphics requires specific type of discrete graphics card installed in your notebook. You can find some info here:

So with my A4 I can't install second GPU like HD 6510G2 because it should be already installed on the motherboard right?
I read that dual graphics is not so helpfull. It's more like saving power is that rignt?
