I would recommend a CPU upgrade as well. Go for an i5 since an i3 won' be a drastic upgrade. It's $160 on Microcenter right now for a i5-4590 when a i3 is usually around $115 online (It's $100 however on Microcenter). Make sure however that the PSU is sufficent. If your getting enough CPU performance however, go for an SSD.
