+ElCapitano It sounds to me like you've already decided to purchase the GTX 1080 Ti, regardless of the advice that you receive here. That is completely fine of course.

Your Intel i7-870 is now eight years old. While powerful back it's day, I would now say that it's modern-day CPU equivalent, performance-wise, would be an Intel Pentium G4560. This chip is a dual core hyper-threaded processor that only cost $65 USD on NewEgg.

The user below paired a i5-750 (LGA 1156) CPU with a GTX 1080, and showcased your point: While the bottleneck is present, it was diminished somewhat when he transitioned from the 1080p to 4K resolution game play.

Your i7 is a first generation model. The best you can put in your system is a GTX 1050 Ti. A 1080 Ti would be a HUGE bottleneck. You'll probably need a high-end 7th gen system to take advantage of a 1080Ti.

You should consider a 1050Ti, or get a new build if you want a high-end setup.

How so? I have 2 gtx 760 oc'd in sli already so the 770 would be a downgrade. Anyone got a decent answer please?

The 1050 would be fine but I want 4k gaming so it seems that the cpu is less relevant at those resolutions. I will be upgrading my cpu and motherboard within the next 8 months so it seems like the right idea to do the GPU first.

Listen to them- they answered your question already. Your I7 is first generation, there WILL be a bottle neck with a gtx 1080ti. They gave you the best answer- a very "decent" answer.
4k does need a fairly decent CPU too, so dont forget about that. My recommendation- wait until youve upgrade that old i7 then do the graphics card. Incase you become short of money at all, a high end cpu and a medium end gpu is better than a first gen cpu and an overkill gpu (compared to the cpu)

Kind of funny, but the thing that would frustrate me with that chipset is whether it was limited to only SATA 2 (3.0 GBps), thereby cutting my SSD performance in half. I had trouble locating YouTube performance reviews of the i7-870 with Pascal GPUs. My hope is that the 1080 Ti would be compatible with your current motherboard with the most recent update. If not, then one suggestion is that you could sell your CPU, MB and RAM as a bundle on Ebay and use that money to purchase the beginnings of your future rig. You could get an equivalent Pentium G4560, and Z270 or B250 chipset MB and 8 GB of DDR4 RAM. Then in eight months, when you have some additional money saved up, you could use those funds to update your processor to an i5-7500 or i7-7700K (! B250 business class motherboard does not allow overclocking).

! Caution: Kabylake (nor Skylake) CPUs are not compatible with Windows 7, so you shouldn't consider making the switch unless you're on Windows 8.1 or 10. The issue has to do with Microsoft not having native USB 3 support in Windows 7 for those platforms. There is a workaround, but I doubt that you'll want to deal with the hassle of it.

GTX 770??? I suggest to OP to buy a new CPU. Having an old CPU shouldn't be reason not to upgrade GPU. Could even just get a locked i5/i7 like Skylake/Kaby Lake. Or since you probably need a new motherboard anyways you could get Ryzen. Not sure if a motherboard that supports i7 870 would even support a new GPU either way.

The 1080ti performs very well with my 870, with no bottleneck that's noticeable at 4K resolution, if I drop to 1080p then the bottleneck appears massively. but I'm getting the same FPS as others are getting with much newer CPU's at 4K so I'm more than happy with it.

Thank you for sharing your experience. It's very helpful to know that from someone that has hands on experience. You should consider posting a video on YouTube. You'd probably have game play content that no one else does with that combination of processor and GPU.

60fps @ 1080p or 4k takes near enough the same cpu work, the extra workload is on your gpu. If your CPU gives you playable framerates on your current setup that won't change by moving to a 1080Ti and 4k. I would expect your CPU to struggle with 60fps in the latest cpu demanding games but it should still give playable framerates.

I agree with rcald2000, you should upload a video of this.



I look forward to checking it out. Also I'm curious if your 870 is overclocked at all, and I wonder about the other components in your PC. I'm sure you must have overclocked the 870.

My CPU is oc'd to 3.8 on air. I was at 3.9 but was suffering random crashes (although not often during gaming, more during internet surfing)
8BG Ram
1080 Ti
Asus P7H57D-V EVO

Ignore the shit gameplay, it was purely for a test. The framerate is usually 4-5FPS more when not recording
