    I am considering buying buying a Dell 1420, and it comes with a Core 2 Duo 5450 (1.67Ghz, 2MB L2 Cache, 667FSB). I would like to use the laptop to decode h.264 1080p videos and was wondering if that was powerful enough to do it without dropping frames.

    Also in general, what is the minimum CPU requirement to play 1080p videos smoothly?

    That C2D isn't going to be enough. What you should pay attention to is the GF8400's specs it should be able to offload the processing. For instance my V5200 video card can do 1080p decoding keeping CPU relatively low.

    I have played samples of 1080p smoothly on my notebook, AMD Turion 64X2 1.6Ghz and IGP ATI 1150 no problems. By decode you mean play right? Your C2D is faster than mine.

    Yes it will be fine. Check out my Benchmark thread in the Dell section for a lot of benchmarks on the 1.5GHz processor.

    The C2D should be enough, especially if you pair it with a 8400M GS.

    As far as I know, the V5200 (based on the X1700 I believe) only offloads some processing from the CPU - Only PureVideo HD and more recently UVD are capable of offloading the bulk of the processing to the GPU.

    Sorry what I meant was if it was a C2D alone it's not gonna cut it like a C2D with an Intel 950. It was a desktop and it was terrible dropped frames most of the time.

    If you can pair a C2D even say a 1.3 Solo with Discrete Gfx like an 8400 or even and X1300 Radeon you don't get many or any dropped frames. A capable card should be able to hardware deinterlace (putting the "P" in 1080p)without breaking a sweat which is the bulk of the processing.

    In today's computing most of the HD content (decoding) is handled by the GPU and done really well.
