Really fast, because I donāt have much time this morning, a CPU upgrade would help significantly. I run an A6-3650 which is quite comparable to yours, and also notice when I hit the flot, I get big fps drops. Your suggestion of the i5-3350P would get you about double the performance of you current CPU (edit and about a 40% increase in single thread apps, which BMS is - see single thread score and 4690 would effectively put you at double @ 2228 not shown in chart) If you are going to drop money, you might want to spring for just a tad bit more, another $30 or so will get you a significantly better price performance ratio, like an i5-4690. I need to point out to you, that you will need a new mobo, as your old mobo supports LGA1156 and i5-3350p is LGA1155, and even 4690 is LGA1150. The sockets must exactly match the CPU a 55 wont go in a 56 mobo - pin incompatibility, different voltages.
Also, your GTX 650 is more than likely probably not up to the task, so you might want to look at replacing that with something stouter (like a beer, no j/k) like GTX 570 and up, or R9 270 and upā¦.
