I was wondering if Athlon II X4 640 @ 3.3GHZ will bottleneck a GTX 760? Because I seem to be getting really low fps on some games for that card. like 20-30 on NFS most wanted,tribes ascend,crysis 2. And the gpu usage never goes over 30-40%. Because I heard and read that even the phenom II X4 will bottleneck that card. I just don't seem to be able to use it all or get a constant 30 fps in games with it when i should be able to. I have a Rosewill HIVE-550 modular PSU,8gb ddr3 1333,326.80 drivers. And I play at either 720p or my actual resolution of 1440x900. I have tried low and max settings all of those games and the framerate doesn't(somestimes does, but doesn't get better) really change. Sometimes depending on the game if I take it from maxed to lowest it actually gets worse.

Yes.
Every game varies though, but yes you will be very bottlenecked by that CPU in many games.

However,
There might be a problem somewhere. Look at this:

I'm not sure which card is faster, the 760 or 580 but you should at least be in the ballpark of these graphs looking at the AMD 645 CPU.

*I'll try to come up with an explanation for this. Verify that all four cores of your CPU are working (Task Manager, Ctrl-Alt-Del, Performance... show all cores.)

Your CPU is certainly a bottleneck for that card. The 760 is essentially a 670, so yea. If you were to upgrade, what kind of budget would you have? Also, the last comment seems real awkward. How old is the card?

About 3 days old. its an EVGA GTX 760 ACX(non-oc). I meant sometimes that if I put the settings on low in games I get lower fps than maxed(or close). Not sure what CPU would minimize or get rid of the bottleneck for it though. Any suggestions? The lower the price point the better.

It's possible there is an issue with your drivers.

1) go to your motherboard support site
2) open the proper Windows version (i.e. W7 64bit)
3) download and run the MAIN CHIPSET driver.

4) If you haven't, download and run the latest NVidia driver.

*If you're still stuck I'll try to help as I think there's a problem. Your CPU would throttle but not that much.

temps at load are 58-60c And don't have a main chipset drivers because they are AIO drivers since its AMD and my board has a IGPU. Also they are win7 64-bit drivers and I have win8 64-bit but doubt that would make a difference for chipset drivers.

RUnning Windows 7 drivers on Windows 8 could cause issues. Also, can you disable the IGPU? It may be trying to run from that for some reason. Since the card isn't hitting 100% usage like it should that may be the issue.

It doesn't effect it. I did have it disabled and it didn't affect my usage at all. The only reason I use it is to run my 2nd monitor till I can get an adapter to run it off the card. I can try it again with crysis 2 which I didn't try the first time.

Questions:

1) Do you have #1 Monitor attached to the GTX760 and #2 Monitor attached to your motherboard?
(I ask because I didn't think that was possible.)

2) Did you install Windows 8 64-bit from scratch?

3) And just to confirm, you downloaded and installed the Windows 8 64-bit drivers from NVIDIA?

4) Can you give list your MOTHERBOARD?

5) What does your 2nd monitor use for input?
The GTX760 should support VGA, DVI and HDMI. I would have guessed your motherboard output was DVI or VGA.

Yes I have 1 monitor on each. There is a lot people don't think is possible with IGPU that I have done. The only drawback is its an ATI IGPU so it disables PhyX from working on my card. It is win8 64-bit from scratch yes. And yes they are the win8 drivers. 880GM-LE FX, input is VGA.

Even whilst running a single Monitor?

I'm actually a little stumped, plus it's hard to do troubleshooting over the net.

I've got only two ideas currently:
1) verify CPU is using all four cores

2) Reinstall Windows (ideally to a spare driver, just to check things work.)
- install Windows
- install MAIN CHIPSET from motherboard support site
- install NVidia drivers
- Microsoft Updates (can take a while)
- run a benchmark utility (3DMark or anything repeatable).

So you could run a BENCHMARK utility now, then reinstall Windows and REPEAT that so you'd know right away if there was a difference.

Sorry this is all I can think of.

Alright. I can't really reinstall window atm. And it is using all 4 cores as well. It could be my HDD is that fragmented or my windows install is that bad. I will try that as soon as I get a new hdd though.

It's not a fragmentation issue. Games load most data into your System RAM and Video RAM from the drive and run it directly from the faster RAM. At worst you'd get stuttering in a poorly coded game that regularly access the drive for textures but that's extremely rare and wouldn't affect the average frame rate much.

Again, your CPU is a bottleneck but I linked a benchmark earlier that suggests your way too low. Since all four cores are running in your CPU the only other thing that could bottleneck that much is your graphics card.

Thus, the ONLY idea I have right now is that it may be a glitch causing the card to run in 2D mode since you mention 30/40% usage.

Other than reinstalling Windows the only thing I can think of (that may have been mentioned) is:

1. Google for a good video driver cleanup tool and download it.
2. Delete the video drivers.
3. Run the cleanup tool.
4. Reboot.
5. Install the latest NVidia drivers downloaded from NVidia's site.

*Again, if that doesn't help and you decide to reinstall Windows run a BENCHMARK utility that you can easily repeat so you can quickly know if the new Windows installation solved your issue. KEEP this benchmark written down (if successful) for future testing so you can confirm your system still works.

Feel free to ask questions. They can help us diagnose the problem. I doubt your card has a problem, but it is always a possibility.

I definitely feel that your CPU could be a bottleneck in some games but your GPU usage is so low that that cannot be the explanation. I had a friend using crossfire 6970's on a Phenom II X6 without issue. Your hard drive, even if it is fragmented, is not the problem.

Do yourself a favor and just leave the onboard video disabled (disable it in the BIOS) and use only one monitor while troubleshooting. As others have mentioned, you likely have a driver issue. It is probably either an nvidia driver issue or a chipset driver issue. What motherboard do you have? Do you have the correct Intel RST installed? What mode is your drive running in, RAID, or AHCI?

Personally when I test computers I prefer to use a brute force approach. Heat and usage are reliable go/no-go indicators of whether something is working or not.

Get a program like speedfan that can monitor your temperatures. Then run Intel burn test or Prime95 (run at least 4 threads to ensure the CPU is fully utilized) for a minute and report the maximum core temperature you get. Then run Furmark and report the maximum GPU temperature (you may need to use your GTX 760 card manufacturer's tool to see the correct GPU temperature) you get.

My HDD runs in AHCI,onboard is disabled. I have the 880GM-LE FX. I have done prime95 and it is running at full capacity. My GPU never goes above 58C. Also another thing I noticed is that it likes to change the clocks a lot. Like underclocking for power saving then going back up to meet demand. In some games like minecraft it stays at 2d clocks.

That is very strange indeed. I cannot possibly guess what is wrong at this point. It is hard to diagnose these things over the internet. The only thing I would suggest is to continue trying different drivers for your graphics card.

The other thing to check is the motherboard. You did not mention which motherboard you have, but in all likelihood, it has multiple x16 PCI Express slots (the long ones the graphics card goes in). Ensure that your graphics card is installed in an x16 slot that is actually running at x16. Sometimes motherboard manufacturers will build a motherboard with multiple x16 slots but running at different speeds (x4, x2, even x1) to provide maximum compatibility while keeping costs low. Usually the highest speed x16 slot is the one closest to the CPU.
