The first pc you mentioned is very nice! 4th gen. i5 with 6mb of cache, 8GB of RAM, Nice SSD, if you can afford it that is good!
I am not real up on all this, but I would try to get the latest Intel hardware that I can, again - unless you are getting a good deal on an older model. The latest i5 would be a Generation 5 like these: http://www.intel.com/content/www/us/en/processors/core/core-i5-processor.html But, I think nothing wrong at all with the 4th gen i5 on the Asus.
Pentium 2 Core E5700
WD Blue 500GB HDD
G41 Express Chipset
8GB RAM DDR3 400Mhz
This is your current pc? that is good! The cpu looks a little dated but is plenty for what you want to do and is Dual Core! I think maybe it needs a good cleaning and you could keep using it for a while. You have plenty of Drive Space and RAM. And, you are saying you have Windows 10 on this? this is good also! If you are inclined, I would go to another section of bc.com and get some help to see if your pc is a little infected or needs a good cleaning, what do you have to loose?
Here is the windows 10 section:
If you upgraded to Windows 10 then this will be a good place to start.
Or you can go to "Am I Infected" here: http://www.bleepingcomputer.com/forums/f/103/am-i-infected-what-do-i-do/
Read the Pinned Topics at the Top of the page to get an idea of what is to be done, it might be fun for you to learn this stuff.
