My build:
AMD FX-8120 @ 3.1 GHz
8 GB Corsair 1333 Ram
Thermaltake 700W power supply
SATA 1 TB HD 7200 RPM
Asus 3GB GTX660 TI-DC2OC GPU
MAGNAVOX 19" LCD TV running at 1920 x 1080 resolution.

My issues: I run certain games such as Team Fortress 2 and Dota 2 at max settings and get 70+ frames, but on other games like Borderlands and Killing Floor, I get FPS drops as low as 15 FPS. Changing the resolution for those games does not help, and turning down the graphics only helps if I go below medium settings.

My friends with lower builds run better then I do, my card does not overheat, and as far as I know the CPU isn't bottlenecking.

I also cannot get my GeForce Experience to install the newest version, or run when I have older versions installed. I have the most up to date drivers.

It could possibly be a driver problem. I've had issues like this where some games lose performance when installing the newest Nvidia drivers (I also have a 660Ti). I would suggest running driver 314.22 or the 320.49 driver, they seem to work the best for the 660Ti.

I've also had trouble installing the Geforce Experience. What I did to get it to install correctly is to just keep trying after it fails. If it fails, I tried to re-install it, etc.

It is CPU bottlenecking. Same things happens to me with my FX-6300 and my GTX 770 for Borderlands 2, except I only go down to 30 fps. Still, I hate it. It's an unfortunate thing I've discovered with AMD budget CPUs: In CPU bound games you will get considerable bottlenecking sometimes, and Borderlands 2 is exceptionally CPU bound:

What you can do to mitigate this somewhat is do a good stable overclock. 3.1 GHz is quite low. You can probably get that to 4.2 GHz pretty easily with a good heat sink, but in my experience the results are anywhere from a 6 - 12 fps boost. It will really vary greatly, but still, try it.

I'm not sure a 8-core, 3.1GHz processor would be enough to bottleneck a 660Ti, but of course, a decent overclock could add a few frames.

Oh I should also mention I am running Windows 8 64 bit. I don't know if overclocking is an option without a program to do it for me, since I believe Windows 8 locks access to BIOS

It's not as simple as cores and clocks. If it was, then AMD's 8 core, 4.0 GHz CPUs would outperform Intel's 4 core 3.4 GHz CPUs every time, but they don't, and most oftentimes it's actually the opposite. When it comes down to it, it's all about architecture, and the FX-x1xx series (Zambezi/Bulldozer) was terrible in its architecture, with many people citing its predecessor, Phenom II, as being far superior. Most games don't use more than 4 cores in the first place, and frequency really means very little in the end.

Perhaps part of this is graphical issues, but overall my own experiences with my FX-6300 and numerous other citings tell me it's due to how crappy AMD's current architecture is. I'm hoping that since they've secured all ends of the console market, maybe soon it'll help them in some way in building better consumer CPUs but until then you'll have to make do or try an Intel build.

That's not how it works. The BIOS can't be locked by your OS, that would be completely non-sensical. Your BIOS is the go-to thing when all else fails. The idea of something locking it is literally impossible, because your BIOS has the first say in absolutely everything when your PC starts up. Your CPU takes instructions first and foremost from the BIOS. It's only when the BIOS tells it to look to the OS for instructions does the CPU even realize the OS exists.

Well, my pc has no UEFI options, and it will always skip over the boot menu, even if I spam f2 and actually get the menu to come up, it will flash for about 5 seconds then Windows 8 will start and override it.

That's seriously weird. I've never heard of that. There must be something else going on, because it makes no sense that an OS would be able to override your BIOS. You could just try unplugging your HDD for now and then going through the bios.

Maybe someone can explain the science to me, however I can play games like BF3 on ultra settings on 1920x1080 at 70+ frames, with very rare drops to 40- depending on if lots of explosions are going on in 64 player rooms. If I don't play in 64 player rooms, I don't ever see FPS drop. The same thing happens on Killing Floor, normal rooms I play on ultra and have 83 fps, but when I join a custom server with a lot more zombies per wave, and more players, I suddenly suffer FPS drops, sometimes down the teens.

Is this a CPU issue? Overclocking my card doesn't seem to help gain frames at all on any of my current games, they all exceed 60 frames on ultra, with the exception of borderlands, and I would like to know how to stop the FPS drops so I can continue to enjoy all of my games, and the custom mods that go with them.
