Where is my bottleneck?

I've having some FPS issues in WOW and TF2. I run at 1680x1050 with 2xAA and 8x AF. I will often see 20FPS in busy times, and occasionally in WOW I'll actually see stuttering because too much is happening, which just seems low for my specs (or maybe it isn't?)

Basically...where is my bottleneck, if I want to get to the next level of performance without overclocking where is a good place to start.

C2D E8400
ASUS P5Q SE/R (using onboard audio)
9800GTX+ 512mb
4gb Corsair XMS2 DDR2 800
Seagate Barracuda 7200.10 250gb SATA2 8mb cache
Vista SP1 32bit

Your hardware specs look okay.

Do you have any non-internet connected games to use for performance testing? Are they slowing down too?
Run some hardware benchmarking programs, check temps on CPU/GPU to make sure they're not "throttling" during games.

Have you checked your internet connection? Visit the tools section of http://www.dslreports.com/tools

What background programs and processes do you still have running while gaming? http://alacritypc.kensalter.com/index.htm

Another thing to check is the PCI Latency, i have found in the past that this can cause bottlenecks.

Anything set to "000" can not be changed, i would suggest trying a latency of 32 or 64. I had a similar problem when i got my XI-FI Extreme gamer which was set with a latency of "248" and when i changed it to 32 all of my lagging/problems went away. This may or may not fix your problem but it is worth a try.

*Note. Some motherboards let you set the PCI latency in the Bios.

You have a nicely balanced system.
The bottleneck is probably your internet connection or the server you're playing on.

I bet it is your internet connection or server the game is on....I have dsl at 3 mbps and I have stuttering also occationally but I know it isn't my system! Intel core I7 920, 6 gigs corsair dominator, 1 tb wd caviar and a gtx 295, and a samsung 2493 HM monitor running 1920x1200
