The R7 265 is far better than the GTX 650, and heck, it's even a close call in many games when compared with the GTX 750 Ti. The GPU choice is fine and should do most games nowadays at a decent framerate at 1080p, if you omit crummy console ports from the equation.
As for the CPU, you could likely pick up an AMD Athlon X4 750K or 760K for less than $100, which will fit the motherboard and provide decent quad-core performance.
As for RAM, Zenkid is right, 4GB is pretty barebones by today's standards, and might bottleneck your upgraded system a bit. An extra 4GB stick could run you about $50, but it might be a worthwhile investment, especially if you're a tab whore like me.
Just having my browser open consumes about half my RAM, so when playing BF4 I have to either tune down the graphics or close a handful.
Just make sure the new RAM matches the old ones in speed, DDR#, and you should be fine. If you find more money to spare, replacing all your RAM could ensure compatibility.
