E8400 vs i5 6500

[bazznet1]

Is there a difference between E8400 and i5 6500 for office work? Typical office, internet, e-mail..
Will the i5 make the copmuter run faster?

Is there a video comparison of a new computer vs an old computer for basic uses?

Thanks

The 6500 will be a faster by a lot!
It will improve overall Systemspeed like bootup time and opening programms.

Here is a rough overview how much faster it is: http://cpu.userbenchmark.com/Compare/Intel-Core2-Duo-E8400-vs-Intel-Core-i5-6500/2720vs3513

BUT: if you havent bought anything yet then you should go for the newer and better I3-8100. This CPU does also have 4 Cores with 3,6Ghz but comes in at a much lower price

In tasks determined by human typing speed, the difference will be slight. In anything machine-dependent, the i5 will utterly blow the E8400 out of the water. Keeping in mind that you'll likely be running Windows, and should have anti-virus and other security software, likely a backup scheduler, and other programs running at the same time, you'll definitely want the i5.
If the option is available to you, an i3-8100 would make a good choice. It also runs four threads like the i5, and being a couple generations newer, should have a higher IPC and perform as well or better. The difference between that and an i5-8400 would probably go unnoticed for most office work.

For most office tasks, there isn't a big difference (unless you've got like 50 browser tabs open and like to switch between them a lot). Your biggest speedup will be switching from a HDD to a SSD.

The three big reasons to upgrade from the E8400 for office and Internet tasks are:

• 
  ■Power consumption. I had an E8400 system about 10 years ago. It used about 75 Watts at idle, vs about 30 Watts for a modern desktop. If you leave a device on 24/7 and you pay the U.S. average of 11.5 cents/kWh, every Watt = $1 in a year of use. So the difference between 75 W and 30 W is an extra $70 - $35 = $45 in electricity bills every year. So after about 5 years, that $500 it would've cost you to upgrade to a newer computer is actually only $275, because of all the extra electricity you would've used running the older computer. Scale this up or down depending on your electricity price, and how many hours/day you leave the computer on.
  ■Streaming video. Regular video playback (like from an AVI file) is done using the GPU to decode the compressed video. But Hollywood insisted that streamed video (like Netflix or Hulu) be decrypted inside an encrypted virtual machine so the user can't simply capture a copy of the video stream to make a copy of the movie. This requirement makes it impossible to decode the video using the GPU. It has to be done by the CPU. An E8400 may be able to decode a 720p video stream, but won't be able to decode 1080p video in real-time. Even the early i3s struggled at that.
  ■USB 3.x support. USB 2.0 is limited to about 25 MB/s real-world transfer speeds, which is much slower than most external HDDs and flash drives are capable of. USB 3.0 raises the ceiling to over 200 MB/s.

I too would recommend an i3-8xxx over an i5-6500. Although I've seen some really good sales on i5-8xxx desktops but relatively few i3-8xxx desktops. So depending on what sales you see, a i5-8xxx desktop may actually be cheaper.
