My CPU Bottleneck?

Yes, it is bottlenecking badly. You should overclock it. Fortunately your CPU can usually overclock like crazy, even with stock air cooling and default voltages. What motherboard do you have?
i have a foxconn Foxconn P9657AB-8EKRS2H

and unfortunetely i dont have any experience with overclocking. how much does my CPU need to be?
i was reading the OC tutorial but some of the things don't match up with my mobo

Even if you hit 3.4 it will barely enough for that video card. Get either Thermalright ultra 120, thermalright true cooper, sunbeam core contact, or Xigmatek 1283. Sunbeam is the best choice unless you use 2 fan push-pull on other fans. And it is $29 after $10 MIR

No exception. Still need to overclock it.

What are you whacked?
3.0GHz is more than needed for the 280 gtx and to play games at max settings.
Op OC the CPU to 3.2GHz, (FSB400x8multy) RAM set 1:1,and you will be golden!

3ghz is enough, it but the higher cpu frequency the better that graphic card will perform.

Im going to have to counter this by saying that my GTX280 sees benefit when I OCd(more) my E7200 from my normal overclock of 3.6ghz to slightly more extreme 3.8ghz.
Exactly. A lot of people who have been overclocking for awhile take it for granted. You can kill your CPU (dead, nada, non-functioning, muerto, etc) if you don't learn what your doing. Remember, they are giving you advise on YOUR machine, there not out the money if it dies.
Having said that I overclock every CPU I own. If you decide to, read up on it. Start slowly and watch your temps. Make sure your power supply is adequate.

I would have to disagree. My E6600 @ 3.3GHz was bottlenecking my 8800GTS 512. I'd get 100% CPU usage in Left 4 Dead, and don't even get me started on more CPU intensive games like SupCom. Of course, the bottleneck wasn't very big, but still. Now keep in mind that a GTX280 is at least twice as powerful as a 8800GTS 512...
to the op
i have a stock clock q9300 [2.5ghz]
i played around with it from stock up to an even 3ghz
ive tested a range of video cards with it - from a single 4850 512mb up to the 4870x2
with the x2 i was playing crysis @ 1920x1200 with optimal settings [all high]
3 of my cores were busy, 1 was obviously on vacation...
my total cpu usage was between 50 and 79% - the 3 active working cores never pegged at the top but flexed through a normal working range
im not saying you shouldnt oc your current chip - at this point yes, it is indeed a bottleneck to your 280
but i can say with conviction and proof, that a c2quad at 2.5ghz is not a bottleneck to the highend video cards when playing - crysis or dead space or the two newest cod games
those were the only few i got to test before i had to give the videocards back to their rightful owners
there's something to be said for the rest of the system config then - in the system in my sig im no where near a cpu bottleneck in left for dead
granted im running a quad vs your two - but you're pushing 800 more mhz than i am?
odd...
left for dead is another game that uses all 4 cores though - this is in windows beta 7 with a licensed copy of l4d via steam
The fact that you're getting 100% cpu usage in L4D doesn't mean your CPU is bottlenecking anything. It may just be the way the game is coded. For example, I still play Jedi Knight 2 (JediOutcast) and that game says 100% cpu usage even though my AthlonXP 1800 ran it perfectly fine back in the day. I find it hard to believe that an E6600 at 3.3 would bottleneck a GTS 512. Would an E6600 at 3.6 show some improvement with the same card? Yes, a few FPS here and there but nothing monumental.
As for bottlenecks, there will always be bottlenecking of some sort. In order for there not to be any, all elements of hardware communication would have to be on a 1:1 basis. What I mean is that for every instruction that the GPU sends, the CPU is able to process it at the exact same speed. But since GPU's and CPU's vary, one or the other is always lagging behind.

aside from taskmanager, do you guys use anything else to monitor cpu usage?
Nah, I would get CPU lag in Left4Dead and SupCom. It wouldn't be anything too terrible, but you could definitely feel it. I use G15 keyboard to monitor CPU/RAM usage.
