You won't have a GPU temperature "in-game". However, with GPU-Z, you can record your temperatures. So, start recording just before launching the game... play between 5-25 minutes...quit the game...stop recording and then check your recorded temperatures (the graphs should indicate how fast it raised, etc.). If you want the easy way out, GPU-Z will indicate the highest temperature it went to without you ever needing to record anything. CPU-Z works the same way (if you ever wanted to check temperature on your CPU).
ALSO I wanna say that msi afterburner doesn't check the gpu temp in idle mode as then intel hd 3000 is in use. However, it shows ati hd 6700m as the gpu (m using leshcat drivers 12.3 drivers). i mean there is no option for monitoring gpu temp itself. In hardware monitoring in afterburner, all i see is gpu usage, fan speed, fan tachometer, framerate. Is that fine???
