More on CPU specs of the ReadyNAS Pro

Has anybody tried an Intel Pentium E6800 (LGA775, 2 Cores, 2M Cache, 3.33 GHz, 1066 FSB, 45 nm, 65 W TDP)? It was cheaper at retail, but currently costs more and is more difficult to find on eBay. Here's are some links to some comparisons:

TRANSCODING TEST
I went ahead and performed some rudimentary benchmarks, and it seems that the C2D E7600 performs slightly better at transcoding as expected. I down converted some videos to 720p using ffmpeg for AirVideo 2.0.00. I used this command for all files:
ffmpeg -i FILENAME.EXT -t 300 -vcodec libx264 -crf 23 -preset ultrafast -s hd720 -acodec copy FILENAME_PROCESSOR.mp4 -vstats_file FILENAME_PROCESSOR.txt

This is what ffmpeg reports:
C2D E6700
[libx264 @ 0x8da2ea0] using cpu capabilities: MMX2 SSE2Fast SSSE3 Cache64
C2D E7600
[libx264 @ 0x8dd0f80] using cpu capabilities: MMX2 SSE2Fast SSSE3 FastShuffle SSE4.1 Cache64

TEMPERATURE
I checked frontview during the last minute of each test and there really wasn't much of a difference in heat measurements, although the C2D E7600 reported lower for me overall.

FILE COPY TEST
I wanted to see if there would be any noticeable difference transferring files from share to share, but there wasn't any real difference. I didn't think to get out the stopwatch for precise time measurements, but the log files generated indicte each process completed within five minutes.

The real interesting part is when I deleted the subsequent folders with Windows 8.1. I deleted the folders before installing and running the test with the next processor to free up drive space.
Windows hovered around 94 items per second deleting while C2D E6700 was installed.
Windows hovered around 85 items per second deleting while C2D E7600 was installed.
Perhaps there is some merit to the hdparam scores? Not at all scientific, but more to add to the puzzle.
