I had bought a windows 8 laptop and completely removed it and install 3 Linux Operating systems. To do this, I had to disable secure boot on a UEFI system. Read this link to learn multiple options of dualbooting windows 8 with Ubuntu.
As far as your computer slowing down, that would depend on what you are using it for. Any system running beyond its means will experience a reduction is speed. Linux is not know for slowdowns however. "Overall, Linux is not known as a resource hog"(http://howto.wired.com/wiki/Speed_Up_Linux). Generally, linux is pretty fast. Some, faster then others. However it depends on what you are running.
If you want to check resource usage under windows 8 look at this link.
Reducing CPU usage:
These same fundamentals can be applied to linux. Use search keywords like, Increasing computation in linux, memory optimation for GNU/Linux, Low resource open source applications, linux distros under 512MB of RAM.
The more narrow and precise your keywords the better results you get. For instance, here is a link dated back in 2008 about speeding up linux.
Point I am trying to make, whatever you are trying to use your system for, research system requirements and make your decisions based on that that.
