TBH I don't think the Titan XP (Pascal) is terribly expensive for what it is. I know that sounds fucking bonkers but let me explain..
It's 37% faster in DX12 than the 1080 stock for stock, right. Yes you can overclock the 1080 to within about 15% performance very easily. However, The Titan XP needs water and let's face it whoever is spending £1100 on a GPU will more than likely water cool the fucker any way. Once you do that you gain back your 22% and it again becomes 37% faster in DX12 (and 34% in DX11 in case you were wondering).
OK so it's an insane amount of money but it's the ONLY single handed GPU on the market today that can run 4k with acceptable frame rates (not less than 35 and 60 on sync) without having to rely on anything but a half decent driver (which Nvidia usually present any way). So therefore it's the only single GPU 4k card in the world. SLi and Crossfire have been utterly fucked by these new APIs and are yet to be fixed so to me any way (if you were running a 4k screen) it's actually not that bad. I paid £1400 for my attempt to run 4k (two Titan Blacks) and I failed, because SLi would constantly let me down (Wolfenstein and so on simply didn't support it and one GPU fell apart).
So yeah, daft price but actually quite sensible if you are seriously looking to game at 4k..
As for new rigs vs yours Hearth? they will demolish it mate. There's around 40% IPC between your I7 and Skylake and they run at around 1ghz faster in the least. So yeah, they'd simply smack your bitch up.
Stop being a tight wad and get your hand in your pocket
Oh yeah talking of PCs. I've been working my guts out modding mine recently and making custom parts for it. They're all made, shaped and sanded I just need to paint them. Problem is I live in a flat with no garden. So I made a paint booth lmao.
I saw this on Ebay for £60.
Then went off to the website that manufacture it. I saw pics of it in pieces then decided I pretty much had everything I needed to make one for almost nothing. Two plastic storage containers, three Delta high SP fans (two 120 and one 92mm) and then I just needed to order the primary filter mesh from Ebay and cut open an old pillow.
Back fan test.

https://www.youtube.com/watch?v=S4aDZ2BJ2MAOh yeah and of course I bought this for £2
I also got a crappy respirator for a fiver. It doesn't need to do anything serious as the extractor will get rid of the paint and fumes. I just hope the guy downstairs likes the smell of paint.
