This is a (n almost) complete overkill build simply because I can. It's primarily running an HTC vive consistently at 2.5x supersampling with no issues and doing media encoding, very quickly!
I would not recommend this build at all and you can definitely achieve the same result for far less outlay. I'm fortunate and just wanted to build my 'dream machine'.
I used to build PC's on a regular basis, back in the day and somehow fell out of it and have been,sadly, languishing in fruit land for the last few years. I saw the vive demo'ed and had to have one..hell I wanted VR back in the '90's.... which led to amassing these parts.
Why go to all this expense and not drop in a pair of titan's I hear you ask?.. well I like the lighting and thermal throttling abilities on the strix 1080's and they do the job admirably and I wouldn't want to go completely over the top and remove all upgrade potential :)
It's an amazing system that I thoroughly enjoyed building and is likely faster than I'll ever need for the next fw years at least.
Oh, and I know.. the SLI bridge has since been replaced for a 'proper one' ;)
