Will a Intel Core 2 Quad Q9300 bottleneck a gtx 560ti OC?

More about : bottleneck

hmm, I'm playing Mafia 2 and in some areas my GPU usage goes down to 24% and the frame rate is just laggy and other areas is just fine at 89% usage

I didn't want to make a new thread as I have basically the same question. I have a q9550 with 6gb of DDR2 ram. I plan on getting the new 680 gtx, will there be a bottleneck and how much?

Thanks

Make a thread... it's disrespectful hijacking someone else's thread. :non:

tsukilanh is your Quad OCed? Try a mild OC and see if it improves. salad10203 - nice hijack - 560Ti and a GTX680 are 2 different stories - and is your 9550 OCed.

I didn't mean anything by the hijack, just didn't want to clutter the forums with the same question.

FYI,
Somes games can run FASTER with a better CPU even if the graphics card is the bottleneck. (the explanation is kind of confusing.)

As for upgrading:
1. Open the Task Manager (CTRL-ALT-DEL)
2. Run a GAME for five minutes
3. Close the game.
4. Look at the Task Manager and analyze the results.

Analysis:
You need to see ALL the cores. Hyperthreading also needs to be OFF in the BIOS to avoid confusion. Now, let's assume we're looking at FOUR PHYSICAL CORES and no hyperthreads:

Result #1:
At least one core hits 100%.

Analysis #1:
The CPU is the bottleneck (or close to it). Don't bother getting a better graphics card.

Result #2:
One or two of the cores hit about 50%.

Analysis #2:
You can get a card that scores roughly DOUBLE the framerates as your current graphics card before bottlenecking the CPU becomes an issue.

*This is pretty simplified, and of course not all games can use all threads but if you look at the two MOST used CPU CORES you can estimate how much BETTER of a card you can get then look at benchmarks to see what the card would be.

**Important points:
- test with hyperthreading disabled
- observe ALL cores (view-CPU history- one graph per CPU)
- future games will use all four cores better (meaning a better card can be used for those games)
- GAMES vary their CPU usage. AVERAGE at least four games (two shooters and two Starcraft 2 style games)

no its not OC'ed, still stock. I tried the 560ti on my friends computer, he has a I7 2600k and 16gb of ram and ran crysis, my friends gtx470 was running smoother than my 560ti OC.

thats because a gtx 480 is faster than a gtx 560 ti
