Guild Wars 2

so first in this/next weekend i will clean my PC and OC Phenom, and second i will start saving money for i7, bet it will stay longer in my PC then i5 after upgrade

so i can buy new i5 and OC it, i already have SilentiumPC Spartan Pro HE924

or maybe will wait one month more and then buy i7-4770K and in this time just run on OC Phenom
difficult choice

as i wrote

“im mainly WvW player "

ofc if i change CPU then with motherboard, im gonna target i5-4670K, but i dont know how it gonna work with old Radeon
