I have a Core 2 Quad Q6600 @ 2.4GHz (can't overclock, before it's suggested) and have thought for a long time it's been bottlenecking my GTX 560 since in Battlefield 3 it didn't matter if I played at 1024x768 on low settings or 1920x1080 at medium settings, the average framerate would be around 45-50 fps (so since such a huge change in resolution and a decent change to graphic settings had no change on framerate, I figured the GPU is fine).
But lately I've come across a few more things. First of all, it can't even maintain 60 fps in Team Fortress 2 on lowest settings. That seems a bit... wrong. My old MacBook with a Core 2 Duo 2.4GHz and 8400M could play it at 1280x800 on low settings at about the same framerate I'm getting with the core 2 quad & GTX 560. Additionally, come across someone on the Battlefield forums who is playing no problem with a Phenom II X3 @ 2.8GHz (which from benches on the internet appears to be very very close in performance to the Q6600).
So, is there perhaps something up with my system? Specs are as follows:
Intel Core 2 Quad Q6600 @ 2.4GHz, some Dell motherboard (was a business workstation), 4GB DDR2 memory, 1TB 7200RPM Toshiba HDD w/ 64MB cache, EVGA GTX 560 1GB @ 850MHz, OCZ 600W ModXStream 80+, Windows 8 64-bit
Some things I think I've narrowed down are:
- Not the memory, since I've seen from tests on the internet that differences between 1333 and 2400 memory as well as single-channel vs dual-channel making a negligible difference for gaming, so a few sticks of DDR2 should be fine.
- Not the GPU... It's a GTX 560 lol.
- Not the power supply, there's no crashing or anything
Temperatures seem fine. The GTX 560 is always below 80C. I've ran a 10 minute encoding test to stress the CPU somewhat (running at 98-100% CPU usage) and it maxes at about 75C. Is it possible with an old crummy Dell motherboard that it just can't get accurate temp readings and it's actually much higher? I don't think this is the case, however, since the CPU is not throttling.
Could the motherboard potentially have some issue with PCI-e bandwidth since it's from like 2007 or 2008 so the GPU isn't delivering?
Thanks for any help you can offer. I plan to upgrade anyways within the next couple months but I find it really odd that a Phenom X3 is outperforming it greatly in games and I can't even play TF2...
