Lenovo L520 processor upgrade

Sziasztok.

Tárgyban írt L520-as lenovómat szeretném processzorilag kimaxolni, és úgy várni, hogy majd néhány év múlva szétfüstöljön az egész.

Itt nézegettem, hogy miket javasolnak:

...meg még néhány másik oldalon.

Havalakinek van javaslata, esetleg a jelenlegi 2.1GHz-esemnél jobban teljesítő™ procija, azt szívesen megvenném.
