Bad game performance

[new.puree]

I play world of warcraft and as you can see, my specs are more than sufficient at running the game on full settings. I was able to run it at these high settings with hardly any lag at all. Now I find that I lag just by clicking on characters(it feels like I am pausing all action for a short period of time). And also the performance always gets choppy after about 2-3 hours, when I am in a very laggy and hardware intense area of the game. But when I restart my computer, the choppy graphics go away for about an hour and I have to keep restarting it to get decent performance.

I have not overclocked any component of my computer so I am assuming worn-out hardware is not my problem.
I have a vga fan and also 2 case fans cooling my system and my temperatures seem to be fine when the performance gets choppy.
What could possibly be the problem and how can I fix this?

See if updating your gfx card drivers helps. Look for any updates of WoW.

are you playing online? maybe the particular server you are playing on is just running slow.

if it sdtarts lagging after playing for a while it might be overheating. make shure you have enough cooling in your case
