$65-95 is a tough budget. For about $15 more you can get the i3 6100, which is far faster than either of those CPUs, but if you're stuck in that budget, I have a few thoughts:
Socket AM3+ received its last new CPU design in 2012, and FM2+ its last in 2014. The cores on FX, A series APUs and Athlon x4's are about half as fast as those in a modern Intel CPU. In most cases, AMD's quads (Athlon x4 on socket FM2+ and FX-43xx on AM3+) are similar in overall performance to Intel's Pentium G4400, which is ~$60 on Newegg. The G4400 is on Intel's socket 1151 which will receive 2 more years of new CPU designs, whereas AMD's sockets are already dead and discontinued. The Pentium draws somewhere around 1/2 to 1/3 the power of the AMD CPUs while performing similarly.
There are a few games that just don't run well on 2-thread CPUs, but there are other games that run far better on the Pentium than on the AMD chips due to its far superior single-threaded performance. Both Pentium and FX/x4 CPUs have some pretty serious compromises. The Core i3 6100 is the cheapest CPU that doesn't have any major weaknesses, if you can afford it.
