Graphics card question/problem

Ok lastnight I thought I had really bad lag, I did what become the norm for lagging hours which is log off and forget about GW.

But I just hopped back on and I was still having the same strange lagg effects. Now I say lag effects because, I just considered the recent lag is streaming updates for GWEN, and it wasn't like normal lag so I did some investigation and trial and error (Closed down unused processes, check my connection rate, cmd ping trick). And the slow screen process didn't improve. Now I was also missing the more classic lag signs.

The only thing I noticed was that my ingame ping was still around recent level 300-500, but the FPS was low at 7-5.

Now is that likely the death of my graphics card?
