    yes,,but it can be cured to some extent by using ATI HD 5730 graphics card, 130W adapter and of course THROTTLE STOP.

    Also replaceing the "gooped"/"gloobed" on thermal compound with some properly applied Artic Sliver helps a ton! It dropped by temps by double digits.

    Still throttling is not just temp related.

    Still throttles. If I stress my CPU and GPU to the max and turn my RGBLED brightness to max, it will throttle a lot. If I stress just GPU or CPU and keep RGBLED at lower brightness, it doesn't throttle. Can't think of a scenario in which everything is stressed, at least not by today's standards. When I game, my CPU clocks to 2 GHz while GPU is stressed. No throttling, Crysis at 1920x1080 with all settings max except 2xAA.

    Basically, in realistic scenarios, throttling wouldn't be an issue. In benchmarking/playing Crysis while encoding video while brightness to max (RGBLED max brightness really hurts), then it will throttle and the fact that you do all that at once is questionable.
