Gaming and photoshop editing.
This PC will need to last me a long time. Any advise/thoughts on stability, cooling, future upgrades etc would be appreciated.

My budget is around £1700 -£1800

Thank you

what monitor are you using for this?

i have a view sonic 23" 1080p ips monitor but may consider buying a 1440p. £250 Budget

How into photoshop are you? This spec is overkill (bad overkill, not good overkill) for 1080p or 1440p 60hz gaming.

Trying to tip money over the spec in a bid to 'futureproof' usually doesn't work either.

I think a build with an AMD Ryzen R5 might make more sense, and will leave upgrading to Zen 2 open down the line. An RTX 2060 would be fine for 1440p 60hz gaming; performance is within ~15% of the 2070 but it's only 2/3rd's the price.

Also the 860 QVO should not be confused with the 860 Evo. The QVO is a good deal slower. It's not something I'd buy, and I'd certainly not buy a TB of it.
