Well, i might consider not to, too problematic and it wont work that well, guess i just keep using my old pc until it totally dies and then dump the remainings in the disposal container.

You might ask why not ?

i'll try to explain it a briefly as possible :D

My current setup and all that came before it: back in the good old days building a PC was simple:

1.Ffirst save enough $ Euros Guilders whatever
2. Buy a case that can hold the hardware and is not too large to actually place it somewhere ( space limitation)
3. Buying the hardware:

CPU
GPU
MOBO
PSU
NETWORKCARD ( for the internet)
RAM
FANS

WINDOWS

All very easy cause there was little choice compared to what is available today ≖‿≖

The P100 had a simple basic GPU/CPU?SOUNDCARD
P350 also piece of cake

.

BUT problems appeared buying the first multicore : i5-750
RAM/WINDOWS and other parts no real problem, but it became a challenge ≖‿≖
GTS 250 appeard to be a Bottleneck (+_+)

First Windows on it was good old XP (32 bits) 4 GB RAM
After a while GTS 250 1 GB RAM replaced by GTX 750 ti 2 GB, at first problems seem to be nonexistent
BUT, after a while sh.t hit the fan , seems the CPU became the bottle neck (+_+)

Now years later time to get a new setup ( current setup almost 10 years old) (+_+)(+_+)(+_+) (using w7 64 bits HomePremium)

After this 'mess' a rerun was not what i wanted to have, so the hunt for a CPU began...

Today some good CPU are fairly priced .... after comparing a i7-9700K seemed to be a good deal

thats where the problem begins:

To avoid botllenecking and wasting precious money , you have to search the internet thats where the she ites begins

everywhere they reccommend to get a CPU and GPU that match and thats the problem

The i7-9700K needs a real cooler , dont want to fry things and those coolers are heavvy ... so now the proble is a cooler can sag the hardware , i dont want bend hardware or things to break or tear appart or crush or cause electtric shortcircuiting

So: they all recommend Artic cooler/ freezer, that thing is huge and heavy to be used with the i7-9700K

bad part 2:

You cannot use any GPU, you have to buy expensive one 1050, 1060, and anything in that range are a NO NO
they always recommend GPU that will cost at least 399 or 450 $/ euros well that aint gonna happen, not in a gazillion years

And the final blow is dealt by windozer 10 MickeSoft needs many friend to play so the entire world has to use M$ new toy: windozer 10 , so new hardware wont support win7, and that is too much and the final drop.
Anyway the longer it takes before i am able to get a new one the more relecutant iwill be to spend waste all that hard saved cash.If ans when you have cash and you see a product you like and can buy it right away, you usually go for it, but if you get more time you start to think and consider, and that is bad, this will end up not buyin the product you wanted to.

Could you try and reorganize this into a more readable form? I don't mean "dumb it down", I mean my eyes couldn't keep track of the reading points due to weird syntax and formatting.

When i see things like this OP then i would recommend a console and there most of your worries disappear. Your list of do and donts is quite hopeless for PC building and by that i mean from the text it seems you can't even be arsed to inform yourself of the parts and how they work, coolers are too heavy, you refuse to buy Ryzens even though they have a far better price/performance which really makes no sense since the only games you play according to yourself are 2D ones with low system requirements which any modern cpu would handle fine. You could spend more on the gpu side if you wanted to and get one of the cards you mentioned. Latest Coffee Lake CPU's run hot so you need decent cooling and no the cooler won't break your hardware if you build correctly, i mean follow a guide if you have to.

One problem with pre built PC's is that they skimp on the power supply and especially mobos so if you wanted to upgrade later and overclock it will be very limiting.

Anyway good luck finding something suitable and that it works great.

That doesn't really make much sense. IMO you're overthinking it.

i dont get it

And then 20% decrease when all the mitigations for vulnerabilities are applied.

Lmao!

Build your PC and put that GTX 750 TI in there. You don't like 3D games, so what's the issue?
These days, having a bottleneck usually means; playing GPU-heavy 3D games in 1080P and having an old/slow CPU.

And I don't get your issue with heavy air coolers either. Any motherboard can handle a 1 kg cooler (they use mounting brackets) without bending. Sure, I wouldn't trust the mail service with it - but as long as you handle it with care...
