Is there any bottleneck left?, GTX 295 & Q6600 @ 3.6GHZ

Hello, I have a GTX 295 and a Q6600 and I have heard that a stock clock will bottleneck my graphic card.

So the only thing in my mind was to overclock it to get rid of the bottleneck.

I have pushed my 2.4ghz Q6600 to 3.6 GHZ stable and stressed with OCCT for 4 hours without a crash

And just in case, My system specification are:-

Q6600 @ 2.4GHZ @ 3.6 GHZ - 1.4V
GTX 295 - Stock clock
Asus P5Q mobo
DDR2-800 MHZ @ 960 MHZ 4GB 5-5-5-15
700 watts psu
Running Vista ultimate x64

Playing @ 1440X900, getting a bigger screen next month.

My question is, have I removed all the bottleneck on my gpu? and what do you think of my core voltage, should I try going less or..?

Thanks

You have a bottleneck on that resolution, because there's probably more frames being produced than your CPU can process. If you UP the graphical stress, then it will disappear.

Yup, I'm getting an Asus VW266H 25.5" monitor.

When you play the game, look at the performance tab in task manager. You can Alt-tab to it when playing. If you see the CPU usage at high and stay at high, then you have a CPU bottleneck. I doubt you have a CPU issue. A more likely bottleneck potential is having 4GB of RAM, which can also be checked from task manager and I doubt is a bottleneck either.

His FPS is going to be over 150 always, but that's not necessarily a high-end C2Q.
