[SOLVED] What would be an ideal cpu for my build/usage

[Darthhaggis]

Concise summary:

My PC is ko'd and I suspect it to be either the motherboard or ssd.
That being said I planned to do an upgrade since they are both about 8 years old at this point. Unfortunately that will also mean replacing my current ram and processor which are still working pretty well for me.
I have worked out more or less what I'm looking to buy but I'm far less certain around the cpu. I want something that isn't a step down from my current processor, and that will ideally last around 2 years before I have to consider another upgrade. I've not bought any of the new components yet so if I've made any glaringly bad choice let me know, but I feel pretty happy with it.

Current processor:
I7 4790k haswell

To give some context I will occasionally be doing multiple things at once such as processing short videos while playing a game, which my current processor handles admirably. I also play a lot of strategy games which can utilise my processor quite heavily for managing the ai decisions etc.
I'm running at 1080p at the moment though will likely be moving up within a year or so, it would be good to avoid any significant constarints there though I believe the main one would be my current graphics card.
I don't generally tinker with overclocking much as I haven't found it necessary for what I'm doing.
The motherboard I have chosen doesn't support sli as well which I'm not overly concerned about.
Would look to cap at around £300 for the processor.
Was considering the i7 8700, if anyone can suggest whether this is a good fit or if there's a more appropriate choice for what I've specified above please let me know. Thanks in advance for your help

If it's just the motherboard that's dead you may be able to find a generic 1150 socket motherboard for cheap.

I grabbed this one for a friend so he could upgrade his AMD X4 965 to a 4590 that I found in a dead PC.

^^Besides this I'd probably recommend AMD 3rd Gen this time as the price to performance is a bit better then Intel.

I would consider a Ryzen 5 3600. Gaming performance, vs an i7 8700, would be quite similar, and you save a good amount of money. I would recommend a better quality PSU, as well. What is the budget for CPU, motherboard, ram, and SSD?

Cheers for that logain. I'll need to look at motherboards for the 3600 as although the processor is cheaper the mbs seem to be more expensive, the motherboard I was looking at was pretty good value for what was on it.
Regarding your psu what's your logic on this? Not against changing it but would be good to understand the rationale.
The parts I selected out with the processor were around 300 quid UK, and my upper estimate was 300 for the processor, so all in 500-600 gbp. So about $735 us.

Another advocation for amd, I'll certainly look into that cheers!
Re the motherboard there's a few factors at play, one is my current one was actually quite good. I'd be less inclined to downgrade as it were. More importantly there have been a few issues with it, primarily around behaving oddly on restarts (this could also be the PSU, I haven't been able to nail it down because I don't have a spare to test either).
On top of this I need a new ssd anyway and I'd rather upgrade if I'm having to spend n replacing parts, given i can't actually upgrade anything further on this build in the future (no .m2 slots, can't support ddr4, obviously can't support any new generation processors etc).

Yeah i would go for a 3600 ryzen the maybe add a M.2 if funds allow it then youll still probably have so money left over depending on what you get

EDIT: also do some research on what ram works better with ryzen

Quality, for a PSU, is a must, and that particular unit is not very good. With PSU, a bit over the 600 budget. Yes, the boards are more expensive, but they have at least one more generation, of cpu's, coming it's way. Z390 is most likely not getting anything beyond a 9900k.

You could lower the price a bit by changing the motherboard. The Tomahawk Max ships with the BIOS updated to support 3rd gen right out of the box.

Thanks a lot, this looks ideal for what I'm after!
I'll take the opportunity to switch out the PSU on my current build to identify if it's the source of my odd restart issue as well.
Hopefully I can salvage about 150, 200 from reselling my current parts once I identify the problem components.

Re wild card, cheers for that. It looks like a good motherboard but my reservation is I really don't want to have to replace that motherboard any time soon. My current one has been in my machine for about 7 -8 years itd be good to get similar longevity from this one
Appreciate the suggestion though.
