depends on system as well.

my dual core laptop had an issue where every 10 seconds i would get a 1-2 freeze and it would work fine for 10 seconds then freeze again.

this was related to a bios and gfx driver issue. since this was on my laptop I had to wait 8 months for toshiba to get a new bios update and a new gfx driver for my cards to be able to work.

So I paid 2.3k cash for a laptop that I had to wait 8 months before I could use it with wow. Should have taken the POS back and bought me a different one but the feiance wanted it instead. now I cant get the damm thing away from her :{
