Do you trust AtiTool or Furmark for testing stability??
I just got my gtx 260 today and the first thing I did was run some benches
I only got a measly 14250 on 3dmark06 though lol SO now I'm overclocking and I have the core up to 721 and the shader (linked) at 1566! Furmark says its stable for twenty minutes with temps topping out at 75 C. ATiTool starts and goes just fine for 30 seconds then I get all this weird cube-like crap all over the little window, however it says that there are no errors??
Which should I trust more, Furmark, with no artifacts that I can see, or ATiTool?
