I did a comparison, your processor is horrible, so upgrading to an "AMD Ryzen 5 1600" would be a HUGE performance gain for your PC as a whole. In addition, replacing your video card with a Radeon RX 580 would also give you a huge leap in performance. These are the cheapest "new" AMD parts I found, if these are above your price point then do a little research in similar parts. Try to avoid putting Intel parts in your PC as mixing hardware like that can cause problems. If you do want intel, then replace both processor and Graphics card with Intel parts.
Unfortunately, your Motherboard is also a big issue as it is older and cannot support the Processor I just mentioned (assuming that system model means your motherboard's model). If you have a good chunk of money to spend, and are confident in completely dismantling and rebuilding your PC, I would advise going to pcpartpicker.com and putting that CPU and GPU I mentioned into it, then finding a good but cheap Motherboard, RAM (if incompatible) and maybe investing in a new Power Supply if yours is old. I know this involves pretty much rebuilding your PC from scratch, but doing so will cost only around 600-800$ depending on where you buy and if any rebates are available. It will also get you a VERY powerful machine for the cost as buying a similarly powered PC outright could cost over 1,000$
Finally, before you buy anything, take measurments! The last thing you want to do is buy 800$ worth of parts only to find that your case is too small to physically fit them inside! Measure everything and compare that to the measurements provided by the site I listed so you can be sure that each part will fit and you should be fine. Worst case scenario is a new case which can be as cheap as $40. Invest well, and you'll have a beast of a machine for at least the next 5 years.
