So I know that the APU system is a fair bit cheaper, and that the CPU+GPU will beat the APU in gaming performance.

The real question is: if in the future, would it be worth it to add a mid/low end GPU to the system (like a 650ti, 660, or 7850), or would the CPU performance from the 6800 cause a bottleneck?
Would I need to upgrade the CPU to add the GPU?

Thanks in advance.

The FX6300+7850 is a better solution for more intensive gaming tasks, the 6800K is around 6750 performance from the iGPU, while the 7850\650ti with Boost + 6300 combo is vastly superior in gaming tasks.

How does the CPU + GPU compare with the APU + GPU?

I just did a 5800k build and was surprised to find that it can actually play Crysis 3 smoothly (on low settings @ 1152X864 resolution).

I would be surprised if the 5800k bottlenecked a single 650ti or 660.

Your 6800k should fair better.

With most games today, the GPU does the heavy lifting. As long as the CPU doesn't bottlneck the GPU there should be little (if any) difference in game play.

APUs don't have a level 3 cache, which is generally a boon for gaming. That's why the FX-4300 manages to do slightly better on gaming benchmarks than an A10-5800K, despite being almost identical.

As for bottlenecking, I think you're in the safety zone. At worst, it would be minimal.

For the practical differences between the two CPUs, I am not sure what you would actually find. The 6800k is clocked fast enough that it might make-up for the lack of resources. That said, the FX-6300 *does* have more resources to utilize. The world of gaming is finally playing catch-up with actually utilizing more than one or two cores; so the FX-6300 might age better.

Ok we'll I'm leaning towards starting off with the APU, and then in the future when it is not doing so well I can always throw in a GPU.

As long as you're okay with accepting lower graphic settings for the newer games, go for it. Besides, with some of the money you save, you can use it to invest in a bigger, better GPU down the line. (Although, it might be overall better if you invested in some faster RAM; at least 1866. Depending on how good of RAM you get, you might experience upwards of 20% performance boost, for gaming.)

My significant other has a A10-5800K. She working on Mass Effect 2, going on 3, and they run perfectly fine. I recently bought her Tomb Raider, which will only get decent frame rates when I set most of the settings to low. (Texture quality, level of detail, and depth of field are still at medium.) It's not the enthusiasts' dream, but game is still playable and doesn't look completely awful. I am actually thinking of upgrading my own video card (Radeon HD 6870) and installing it on her computer.
