I have a tough choice too, U46SV or N45SF.

Now that is a more challenging matter. Portability or performance?

Oh no, if I was given a choice for U46SV and N43SL, I'll take the U46SV since both the specs are the same.

But with the N45SF in the equation, better specs at a lower price really messes up the decision.

Why don't someone just use a 120W power adapter and see whether that helps with the situation? Throttling might occur due to over consumption of power as well.

Different amperage apparently. 4.7A vs 6.3A should be 90W and 120W.

Shouldn't be. You're basically giving the laptop a larger supply of juice that's all.

I reported that post already. He's promoting links to some place under the guise of posting something relevant.

Only GT520M unfortunately.

That's why I always said the new A43 series is a far cry from the old A-series stereotype of cheap budget laptop.

Looks like we're overdued for a V13.
