Next upgrade?

Here are my current PC specs

MB: Asus M4A785TD-V
CPU: AMD X3 440 (Arctic Cooling Freezer 7 Pro HSF)
RAM: 4GB G-SKILL DDR3 1600MHz CL7
GFX CARD: NVIDIA GTX 460
PSU CZ STEALTHXSTREAM 600W
CASE: ANTEC 300 (with 3 x Xilence Red Wing 80mm Quiet Fan and 1 x Xilence Red Wing 120mm Quiet Fan)
HD: SAMSUNG SPINPOINT F3 1TB
Misc: NZXT Sentry 2 Fan Controller, Samsung DVD/RW, 1920x1080 Samsung Monitor.

Currently used for gaming, watching blu-rays and general internet browsing. Currently my budget is around £200.

I am not sure what component to upgrade next. I'm thinking on the lines of an AMD Phenom II X4 965 BE. I want to hold out on a SSD until prices drop and capacity increases.

Any help would be appreciated.

Thanx in advance.
