Question Should i upgrade my cpu/mobo/ram?

[Padipadil]

Hey there i have a few questions im currently looking to upgrade my cpu/mobo/ram to use it for the next lets say 4-5years. I play at 1080p 144hz because my graphicscard cant handle 1440p 144hz but i wil upgrade to 1440p 144hz in 2years after upgrading my gpu. Now my question is it worth to upgrade my cpu/mobo/ram at this moment. My i5 7500 sometimes runs at 100% which then makes me lag on discord and stutter ingame it happens when im playing lets say apex,fortnite or rocket league + one or two chrome tabs + discord and some others apps open. Ive seen alot of benchmarks before coming to this website and i know my gtx 1070 will bottleneck the cpu by alot but my next upgrade will be the rtx 2070 super or 2080. The main question is if its worth to upgrade as of now or should i wait for ryzen 4000 series. I also thought about getting the i7 9700(k) but ive been reading alot of posts and people keep saying that it wil and might be running at 100% like my i5 7500 does in like 2-3years especially if i upgrade my gpu.

What i currently have:
Psu: CORSAIR CX Series CX650 (bought 2years ago)
Ram:Ballistix Sport LT - Geheugen 8 GB - DDR4 - DIMM 288-PIN - 2400 MHz
M.2: Intel® SSD 600p Series 128GB, M.2 80mm PCIe 3.0 x4, 3D1, TLC
Gpu: MSI GTX 1070 8g (bough 2years ago)
Screen: Benq XL2411z 144hz DVI
Case: Fractal Design Define S
Storage: Toshiba DT01ACA100

What im looking to upgrade (in the next week or so)
RAM: Ballistix DDR4 Sport LT 2x8GB 3200 Geheugenmodule
MOBO: B450 Tomahawk Max
CPU: Ryzen 3700x

If you have questions feel free to ask them also im open for suggestions like other parts and such.. Thanks for reading!

At least wait till Ryzen 4000.

I don't see how an i7-9700K would be obsolete in 2-3 years.

First of all thanks for your comment i appreciate it! Atm i wont be upgrading and the main factor is that the ryzen 3700x is running very hot in many setups. I mean i know cpus can handle heat but they also said the stock cooler will occasionly sound like a jet to cool it down. I dont mind higher temps but i do mind jet engine fans. In the meantime ill just save the money maybe the 10th gen intel cpus will be worth the money.. anyways ty for reading


And about the i7 9700k imo it just lacks hyperthreatning other than that it would be my go to cpu but no HT makes it just feel like an expensive i5.
