Guild Wars 2

Not without replacing the motherboard as well. Which means you’d be replacing just about everything and building a new pc.

First, few systems can handle large zergs in WvW at a decent framerate. WvW performance is constrained by the CPU and not the video card.

Second, not without major changes to her system or finding a faster compatible CPU for that motherboard. Perhaps used at a local PC reseller or Amazon (I would avoid E-Bay). Going to a quad like the Q8400 or to a must faster dual core like an E8400 will help but it’s not a cheap fix and in the long run a dead end.

You should look into CPU/RAM/Motherboard combos because anything other than a total guts replacement will be limiting.
