    I've been playing a bit of Poker using the PKR application (It's a cider port from what I've seen). I'm finding that on my iMac (and not my MacBook Pro), after playing for a while the graphics go a little bit screwy then it freezes the entire system. To try and diagnose the problem I want to see if it's the app or the GPU which is causing the problem. Does anyone know how I can stress test the GPU?

    What's odd is that even though the app seems to be very CPU and GPU heavy, I don't really notice any fan noise from the iMac. I'm just concerned that it may be overheating.

    Any and all help very much appreciated.

    If your worried about it overheating download SMC Fan Control. It allows to see the temp of your computer and control it's fans :D
