I am currently building a new PC so I'm looking to give away my previous self build from 2011'ish to the kids. What I was wondering is would a modern graphics card, say something like a GTX 1660Ti be suitable for a GPU upgrade. I see from the spec that it still supports PCIe v3.

Will the old CPU & Memory bottleneck the GTX 1660Ti significantly? If I decide to refresh the custom look would a decent overclock help?


  • CPU : Core i7-2700K

  • Motherboard : Asus Rampage Gene IV (PCIe 3)

  • Memory : 16GB DDR3

  • GPU : GTX 580

  • Storage : SSD & HDD

  • PSU : Corsair HX1050

  • Custom Water cooling loop (CPU & GPU) - Needs some work.

Personally I am using an i5-4460 (similar to your 2700k in performance I believe) with a 6 GB GTX 1060 and have not noticed any issues playing Far Cry 5 (which is about the only recent AAA I played) or any other games on a 2560x1080 screen. The only game which forced me to fiddle with graphics settings was GTA V. I have been forced to enable FPS capping in Divinity: Original Sin 2 due to alt-tab issues.

You might notice issues with a higher resolution display.

The only time I noticed a real CPU bottleneck was when rendering 3D scenes using CUDA in Blender Cycles.

  • @PhilMurray you're welcome. Do note that Vulkan and DX12 make CPU performance less relevant as they support multithreading, unlike earlier DirectX and OpenGL

recent member and new as well, but reading about the GTX 1660 Ti, it looks to pretty compatible with most new motherboards, the GTX 1660 Ti uses a single PCIe 3.0 slot at x8 or x16 depending on your system (the longer slots if you're wondering). You can Use AMD and Intel so the difference is not noticeable. I am building a new system and look forward to sharing more information

  • Hi @Olabisi. Thanks for the response but the question was more around will the older i7 2700K processor bottleneck the GTX 1660Ti. From what I can see the GPU is compatible with the motherboard but not sure if it's worth the upgrade. May 8, 2019 at 12:36
  • I apology, I was so broad with my answer. May 9, 2019 at 14:27
