I should clarify that I suggested the 1080 Ti because of being able to future proof the desktop a bit more than with just a 1080. We also don't know what resolution he plans to play at, and a 1080 Ti will definite allow for multiboxing at 1440, or even 2160, if an upgrade was to be made in the future.

Also, here's a quick parts list for the cost I was referring to in my prior post - https://pcpartpicker.com/list/JWFfZ8 (no case, no cooler, pricey SSDs, would also suggest 7700K instead)

When sharing how much load a particular setup runs at, it's important to include many other details, such as...

What resolution are you playing at? What settings are you running? Where are you standing when taking that reading?

I'm standing in the Cathedral Square of Stormwind with two characters running at 60 FPS (7/7/7, no AA, no SSAO) and I'm eating up 45% of a single 900-series Titan-X, which is pretty much the equivalent of a GTX 1070. If I added in a third character at 60 FPS that would be almost the same as running 5 clients at 60/30, and I'm going to guess I'd be eating up just over 60%. However, if I journeyed into The Broken Isles with the same setup, where texture quality is much better, I would imagine I'd be eating up close to 100% of my GPU. I'd obviously turn my settings down, but for someone who does care greatly about what the game world looks like, I'm going to fight for all the quality I can get and not settle for low, low settings.

I'm also a proponent of single GPU vs multi-GPU setups since multi-GPU setups can come with major drawbacks, and a single 1080 Ti would certainly alleviate any bottlenecks in the area of the GPU. However, it might also be wise to wait for AMD's VEGA GPU which comes out in ~6 weeks.

Basically, if Spyder is okay with low settings, then I'm sure a GTX 1080 would be just fine, but if Spyder wants to run some nicer settings, then a 1080 Ti is going to allow for that. Not to sound like Captain Obvious, but it really all just comes down to cost, budget, and need versus want.
