Making films and editing, creating music and having it as a base for recording and gaming.
Basically I'm after a machine that will last a fair few years before needs upgrading without going crazy money hence the £2500 budget.
I'll be using it for work purposes films/music (lots of processing and editing and mixing) as well as my down time with gaming (Total War, CS, HL, Doom, Quake etc)
I have thought about downgrading a few things like 16GB Ram instead of 32GB and a gtx1080 instead of the 1080ti as well as dropping a HDD down to just 2TB instead of 2x2TB but then I think it will probably save me very little money for a years time to be upgrading the Ram and GPU and buy a external HDD so is it worth not buying the better bits to save time and hassle later on

Would the AMD be nvidea compatible? I have had Radeon in the past with results nowhere near as good as nvidea so my faith stands with them.
What Motherboards and Processors would you be recommending as alternatives being as I'v only ever used Intel.
I would like the option of upgrading to SLI at some stage in the future once my needs go beyond only 1 1080ti.
Would 16GB ram be worth downgrading too or would the 32GB ram be the right choice with AMD?
