i5 7600 is comparable to R7 1700x, the top cpu of 5765.  Current price of R7 1700x is $145. GTX 970 is comparable to rx 580. Current price is 250% of what used to be 3 years ago on these relatively old cards.  Expect to pay $250 on eBay.  Local sale may find better deal.
Is it possible to upgrade my computer so that it can handle more demanding games ? Thank you for your help.
