What Intel motherboard and SSD do you reccomend? Also will getting a new CPU mess up my computer in any way?
If you get an Intel CPU, you will also have to replace the motherboard and probably RAM. Those 3 things are the primary components of the PC, should be compatible with your case, monitor, hard drives, keyboard, mouse, Windows, etc.
I don't use video cards, so I'll let others comment on that.
Most Intel processors include graphics capability that is good enough for non-gamers like me and for some people who do mid-level gaming also.
Here are some good SSD brands: Crucial, Intel, and Samsung.
Before choosing an SSD, you need to decide how much capacity you need. My C partition uses only about 40 GB, so I'm fine with a 128 GB SSD that costs about $75.
If you have 500 GB occupied on C, you'd need a much larger SSD than me.
But maybe you can do what a lot of people do: use the SSD just for Windows and applications. Put all personal data on a regular internal hard drive. If you do that, maybe you don't need a big SSD.
Motherboard: if you want to overclock, you'd likely need an ATX motherboard with a Z170 chipset. If not, an H170 chipset is fine.
Look around for that from Asus, Asrock, and Gigabyte in the $120 to $170 range. There's a bunch of them and the difference will be mostly in features--that you may or may not need. Depends on if you have a lot of peripherals that need to be plugged in or have a lot of doo-dads or want to do serious overclocking. I've never spent over $160 on a motherboard.
