Hey, guys. I'm looking to upgrade my computer after a couple years of good use. I can start to feel it age.

I've been out of the loop for a few months now so I don't trust myself on what would be the BEST to upgrade at this point.

I'm looking to spend under $200

Specs as of today are:

Case: Antec 300
Motherboard: ASUS M4A78T-E
CPU: AMD Phenom II X3 Unlocked 4th core @ 3.5GHz
CPU Fan: Coolermaster Hyper 212+
GPU: XFX 4870 overclocked
HDD: 2 500GB WD's
PSU: Antec 550 watt
RAM: 4GB DDR3 Corsair 1333MHz

Any help would be appreciated.
