    Hey all, I want to make my new maxed out iMac suffer in a good way. I want to max it out on the most hardcore GPU and CPU intensive test. Anyone got some suggestions?
    I have cinebench but it wasn't that exciting or reflective of it's performance IMO.

    3.4ghz quad-core i7
    16gb ram
    2gb Radeon GPU
    2tb hard drive

    I'm not sure about GPU, but for CPU I'd recommend Prime95. The stress test is designed to push the CPU load and temperature to the maximum. In fact many overclocker use it to test the stability of their machine, since if the overclocked CPU can stand 24 hrs of Prime95 stress test, it will have no problem handle any tasks in daily use.

    Here is the download link.

    Just keep an eye on the CPU fan speed so you don't fry it with prime95.

    Cinebench is very reflective of the performance (it is a testing standard PC and Mac) it's just brief. And much more "exciting" than prime95. OpenGL is huge in OS X and then it tests single threads and then totally saturates all cores + hyperthreading for multi score. And everyone uses it.
    Tests work because people decide something is a benchmark. You can use a subset to compare and you see whether or not your results are "reflective" of the hardware. You don't use a better test because of a high powered computer you just get higher scores, or in prime95's case, lower scores. The thing you probably want is 3DMark but you'll need to install and run Windows for that one.
