144hz 1080p gaming rig

[cordyknickers]

I'm currently looking into building my first gaming rig to play Rainbow Six Siege at 144hz and 1080p.

I've been looking at the new Coffee Lake processors and like the sound of the i5 8400. However would it be good enough, paired with a GTX 1070, to play games at 144hz and 1080p? Or would I need a better CPU or GPU?

Also, how much does hyperthreading affect frames per second in games? Are the i7 processors worth it for the hyperthreading with gaming?

Any help would be much appreciated appreciated.

8400 and 1070 combo is good:

Just get at least 8 gb 2666+ ram, 16 gb recommended, 2666+, 3200 recommended too. Most games can not benefit from hyper-threading.

Thanks for the reply Vapour.

I reckon the 1070 should be able to keep up with 144hz then if I was to turn down in game graphics a bit as they are using a Vega 64 (which is on par with a 1080) with very high quality settings.

I watched a video on Digital Foundry which showed the i5 8400 using different RAM speeds and anything over 2166 mHz achieved very little gain. Supposedly it's been optimized specifically for 2166 mHz.

Nah, ram speed is crucial or not depends on games and gpu as well. Some games will seem fine, others will show some difference. You never know what game will rely on it, so get the fastest ram you can afford is safe bet. The test you see is limited sample, does not tell a whole story and it can not guarantee new games will not be bottlenecked by the 2133 speed. 1070 is fine, vega 56 is to guarantee no gpu bottleneck and everything is CPU bounded to tell the true diff in CPU.
