Recommendations for PC Upgrades

[Hoonigan]

Alright guys, I have a gaming computer I built about a year and a half ago. Here are the current specs:

Intel Core 2 Quad Q9550 @ 2.83 GHz.
EVGA 780i Motherboard
4 GB G-Skill DDR2 RAM
EVGA 9800GTX+
Western Digital Black 640 GB hard drive
Samsung DVD drive
Corsair 650 Watt PSU
Antec 900 Case

I'm interested in getting back into PC gaming, what do you guys think would be some worthwhile upgrades I could install instead of having to build a new rig?

that is still a capable gaming system ,the weakest point of which is the graphics card. you could upgrade to something like radeon hd 6950 or gtx 560 ti. it all depends on your resolution, games you play, and budget.

I would suggest a after market cooler to overclock your current cpu, and then get a newer GPU. Something of the likes of a 6870 or gtx 560. (Both around $180)
