Help me understand CPU for gaming with a 1080ti

[rondocap]

Ok, so I'm gaming on an x34 3440x1440 with a 7800x and 1080ti gpu. 

 

Help me understand- I know at this resolution the gpu is heavily used, but is the 7800x affecting anything? Would a 7700k give me any more fps because of higher clock speed and bring ring vs mesh? 

 

 

Or at this almost 4K resolution is the gpu what only matters? 

 

Note: I know 7800x isn't the best value for just gaming, but here I'm curious about the above.

Please don't get a 7800X. Get a Ryzen 1600 or 1600X, as it will cost a fraction of the price and deliver relatively equal performance.

[TahoeDust]

No.  There will be no scenario where a 7700k will be able to hit 100fps @ 3440x1440 and your 7800x won't.

7700K would give you a bit more Hz, but, if you're upgrading, you should wait for CFL.

7800x is a lot better for gaming.

I already have a 7800x, and am not asking about value, just performance and if a 7700k would give me any more fps with a 1080ti

Do NOT go from a 6 core to a quad core right now. In games TODAY it may get like.... like 5 more frames best case scenario. In 3 years when all modern i5's, Ryzen chips, and i7's are 6 cores you don't want to be sitting on a quad core chip.

I was thinking of possibly the 8700k if that will give me any gaming benefit at all vs 7800x at 3440x1440

What? No it isn't, 7700k consistently outperforms every X299 chip in the majority of pure gaming benchmarks.

 

Tbh 110 fps versus 107 fps is completely meaningless and the extra cores will give better performance over time.

Honestly I don't think the 8700k will clock as high as a 7800X on a good board.  Stay on X299 and when you feel an itch to upgrade in a few years get a 7980XE on the cheap second hand.

I was saying that the 7800x is a lot better than the Ryzen 5 chips in gaming. He said that OP should, "Get a Ryzen 1600 or 1600X, as it will cost a fraction of the price and deliver relatively equal performance.". This may be true in multithreaded applications like video encoding or other workstation use. However in games, the single thread advantage of the 7800x makes it superior to the 1600x in games and streaming. Yes it's double the price, but OP said that he wasn't worried about money so who am I to get in the way of OP's fun

Not really. Best case scenario for Coffee Lake is like a 5% FPS bump over the 7800x, worst case is it performs like 10% worse.

You'll be stopped by your GPU before anything else. 

 

If we assume that you're running all games with no GPU limits, the 8700K should run much higher Hz, clock for clock and all else being equal, than the 7800X given that the 7700K runs much better frame-rates than the 7800X which has a core advantage.

I'd like to see some evidence for that assumption. Clock speed and IPC aren't the be-all/end-all for CPU's. Cache and core structure are also important. The spoiler contains a video on the 7700K vs 7800X at stock and overclocked.

@rondocap If you want to upgrade or build another PC, wait for Coffee Lake. The hexa-core i5 and i7 with ring-bus will very likely fare much better than any of the mesh or Infinity Fabric chips. 

[TahoeDust]

Overclock your mesh to 3.2GHz and tweek your ram timings to lower latency to get the most out of your 7800x in gaming.

The 7800X is not that much better if at all then a Ryzen 5 1600. Let me refer you to this:

 I think to be fair that was a very early review on a specific motherboard, when the chipset first came out it had a couple of known issues especially with SLI not even working, so most likely those numbers may be different after bios updates now.

What about the ring vs mesh architecture differences between z270 and x299? Even if the 7800x is not going to bottleneck anything, does it being mesh affect gaming performance at all during 1440, ultra wide, etc - with a 1080ti?
