What is the most effective way on testing my site "heavy" on an older devices?

Sup! As the title says it: What is the most effective way on testing my site "heavy" on an older devices? I mean, how do I know if older devices can handle the effects and animations of the site? 

 

I'm not stating old browsers. I'm saying new browsers: IE 11, FF 38, Chrome 41, etc running on older hardware. 

I'm also verifying the site against YSlow and Google's Pagespeed. + Browser's network and performance profiler. 

 

I'm currently in its design stage and I'm planning to use some slide in/out, fade in/out effects using animate.css + jquery + vanilla js 

 

The thing is that I have an i7 4700 mq (no bragging intended) and lots of RAM.  And was wondering how can I simulate a correct environment on testing it on older devices.

Use VMWare and limits the emulated hardware.

If you give the link here, I'm sure people would be willing to boot up an old PC to test for you.

Or, you can try going to a public library. Their computers are generally a little older from my experience. Depends on how old you're looking for.

Parents and grandparents generally have older computers too lol

+1. I was going to say HyperV but essentially the same solution.
