Answers.Text: To clarify, i'm referring to "playing or scrubbing" through footage while i'm editing it. Assuming a constant frame-rate, and constant bit-rate video. In my case i am using MP4 clips.  The harddrive things makes sense, but i have an SSD so not really worried about that aspect of it, nor am i worried about space. thank you for your answer

Answers.Text: If you are editing MP4 the file is compressed, likely in H.264. So your responsiveness in terms of scrubbing, or using a jog shuttle, would be improved by 1.) CPU, both fastest clock speed and max cores. 2.) GPU that supports MP4 decompression with as high a clockspeed as possible, and if Nvidia based, max CUDA cores.

Comments.Text: Well to answer everyone's question. I meant: While editing video on a timeline, scrubbing through it is slow. My i5 can't seem to handle going from one frame to the next without taking awhile for it to show it on my preview window. I'm wondering if lowering the bitrate, or if lowering the video's recorded resolution will make moving around the timeline on the editor faster.

  There are different bottlenecks to consider.
  
  **Bitrate x Time = Size of File.** means **Higher Bitrate requires Faster Hard Drives**
  
  **Compression / Codec / Ratio of Compression** is either processor intensive, gpu processor intensive, or both (depending on your GPU/editing software). Adobe for example, makes use of NVidia's CUDA cores for faster decompression and encoding of compressed files.
  
  High Bitrate, such as lossless, uncompressed, etc, will require high throughput (Fast Hard Disks, from SSD to SAS RAID/Etc) to handle the data rate of the video file to play in real time.
  
  However, uncompressed video requires less CPU processing power, because the CPU does not have to "uncompress" the file.
  
  If you are editing for example, H.264, highly compressed at a variable bit rate, your bottle neck would be your CPU and GPU (if you are using a system which uses your GPU for video overlay output).
  
  **In general:** If you have a fast RAID HDD setup, editing uncompressed is far smoother, more responsive, quicker to render especially, than working with a compressed codec. EVEN with a slower CPU/GPU - simply because the CPU/GPU does very little work / calculations to decode the file.
