AMD FX-6300+Nvidia GTX670= GPU bottleneck. Suggestions for another good but affordable processor/graphics card?

I recently heard that getting an Nvidia GTX 670 with an AMD fx-6300 would bottleneck the GPU. I still don't fully understand what bottleneck means. If someone can further explain to me, it would be great. I came to talk about this since those were the cpu and gpu I was aiming to get for a future build. I wanted the FX-6300 since it was a lot cheaper and, based on some research and benchmarks, could run games in a decent fps. But I don't want it to hinder the performance of the 670.
I know all this could be solved with an i7, but it's seriously expensive.

What I want from the rig:
- To play games (mostly Counter Strike games or GTA games) at 60+FPS on medium or high quality even while recording with Bandicam/Mirillis Action
- To render gaming videos fast on Sony Vegas and Camtasia (for my youtube channel)
(That's why I opted for Nvidia graphics for its CUDA something that was said to speed up the rendering time)
That's pretty much it. I don't plan to do any overclocking on anything really.

I personally like the GTX 670(to be more specific, the MSI GTX 670 Twin Frozr IV 2GB GDDR5)considering all the good things I heard about it along with it's cool name, so I'd really want it to stay. But if there's a better cheaper replacement to partner with the 6300, I'll be okay with it.
Also okay if there was a better but still affordable processor to balance out with the 670.
Basically all I want from a build like this is a much faster rendering time compared to this pentium g630 I'm currently using.

Any suggestions?

  1. The GPU and the CPU won't bottleneck unless if the CPU is overclocked. When my friend overclocked his fx 6300 @ 4.3GHz. It performed the same as my intel i7. We both had the same graphics cards (GTX 670's)

    Bottleneck is a complicated meaning, in terms : its when the CPU doesn't use the GPU fully. This mainly happens with AMD CPU's but bottlenecking doesn't occur when overclocked.
  2. "A bottleneck is a phenomenon where the performance or capacity of an entire system is limited by a single or limited number of components or resources" - wikipedia

    Yep. I knew that. It's just that I really don't know how to overclock, I'm scared to overclock and if I wasn't and actually did overclocking, it would eat up a lot of electricity, I'd need a psu with more power, I'd need a liquid cooling system (which aren't available where I'm at) etc. That's why I said that I didn't wanna overclock anything.
  4. You can try simple overclocks without adding any voltage, you can generally get some good gain out of it without the other major risks like burning out the hardware (I learnt it can be very hard to burn something out on clock voltages).
    If you look into a couple peoples guides about how they OC'd their CPU and what motherboard's they were using. I think the most important thing to remember when overclocking is that you can not reproduce another person's overclock accurately as every bit of hardware, even if the same model/make, is completely different in it's abilities to *over achieve*. So pretty much every overclock is a unique one, but you will find little tips that apply to the OC still.

    Have you had any previous overclocking experience?
    Also what is your PSU?

    Thanks for the info mate. I have absolutely no experience in overclocking what so ever. And is an Antec HCG 620W 80+ Bronze Modular good? Also I don't understand how you can OC without adding any voltage?

    Get an i5 4430 or i5 4570 and there will be next to no bottleneck even on the most cpu demanding games. I think an i5 4430 and up for the gtx670 is perfect. It works even fine on the most cpu intensive games the i5 4430 with gtx670, note I have this config and it works great. fx6300 will bottleneck slightly about 10-20% of the card performance in multithreaded games but on 2 core threaded games it will be a gigantic bottleneck.


    I think the fx6300 is an overated cpu, I have started seeing benchmarks that even a first gen i5 at 2.8ghz beats the fx6300 by 4fps average on battlefield 4 beta. So I would get the i5 4570 if you want to be good for another 4 years, or i5 4430 if you are on a budget and on amd side fx8320.


    While away, I did some research and you're right here. An i5 4570 will probably be enough for me. Maybe if I can, I'll go for an i7 (dem hyperthreading could help with the video editing part) Thanks all.

    FX 6300 is overrated because you're going by one game that was in BETA with no driver optimization??? How about now that BF 4 is officially release with some optmized beta drivers http://static.techspot.com/articles-info/734/bench/CPU_01.png

    As you can see FX 6xxx+ chips hold its own with i7's. The only thing overrated for gaming are Intel chips.

    Play Civ5 a few hundred turns in with an i5 and then an FX CPU and tell me you can't see the difference. The only Intel chips over rated for gaming are i7s because no games utilize the hyper threading, and the fact that the extra threads simply aren't necessary with the sheer speed of Intel's iCore compared to the FX series clock for clock. There's a reason the unlocked i5s are pretty much considered king CPU for gaming.
  9. You never need a high wattage for your components if you had graphics cards in a SLI it would probably only use less than 400 watts and that CPU wouldn't wreck your power bill.
  10. If your gpu is able to run at 99% you should now be worried about an unbalanced system... Hate the b word
  11. I know this is a bit of a late answer but CPU bottleneck is when your CPU runs at 100% constantly in a game due to information draw from the GPU and slows down your computer.

    This is very rare with mid range GPU's, even with lower end CPU's like the Pentium and I3's.

    I run an fx6300 with a very similar card, the R9 280 which is on par with the GTX670 in terms of performance depending on the game....

    My system never bottlenecks..... AND I have my GPU overclocked 1100/1400mhz...
    I get 40-70 frames per second (average about 55) in Battlefiled 4 mostly on Ultra with a few things turned down in 1080p.

    To even get close to a bottleneck you would be looking at a GTX 970 or and R9 290x and even then I reckon it would be fine.

    I've run and built lots of AMD and Intel rigs and the fx6300 is a surprisingly powerful CPU for the price.
