Question Upgrading system - advice


Nov 25, 2014
Current build:
CPU: i5 2500K
Cooler: CM Evo 212
Mobo: Asrock Z77 Extreme 4
RAM: Kingston HyperX 8GB
GPU: MSI GTX 970 4GB 100ME
Screen: LG-24GM77 24” 1920x1080 144HzMonitor
Case: Coolermaster CM 690 III Green
Power Supply: Coolermaster RS750-AMAAG1 Vanguard-S 750w ( 12v: 744w ) | RS750-AMAAG1
SSD: OCZ Agility 3 120GB & Samsung Evo 850 500GB
HDD: WD Red 3TB 5400rpm & various other hard drives

So my friend upgraded his GPU from a GTX 970 to a 980 ti, and hes willing to sell his MSI 970 to me for a cheap price (50 euros).
Additionally to the above my second (Asrock Z77 Extreme 4) mobo has given in, prob due to running the CPU at 4.0

Due to chasflow id like to do a step by step upgrade, so im thinking,
replacing CPU (and cooler), Mobo & RAM with:

Intel Core i5-9600K 3.7 GHz 6-Core Processor
ASRock Z370 Killer SLI ATX LGA1151 Motherboard
G.Skill Ripjaws V Series 16 GB (2 x 8 GB) DDR4-3200 Memory
Noctua NH-L9i 33.84 CFM CPU Cooler

In good time i will then add a RTX 2080 but,
in the meantime id like to run 970 SLI and i was wondering if that is possible with the z390 boards since the 970 is a couple of years old now.
Also would that mobo come with a SLI bridge.
Im open to other suggestions and advice which make more sense.

Thanking in advance :)

yeah itll work
but like
sli is pretty garbage honestly
youll sometimes get the performance of a 1080 or even a 1080 ti!
but then sometimes it might even be worse then just a gtx 970
for 50 euros another 970 is pretty lit and I would definetly buy that
(if I were you I would buy it for 50 and sell it for 120 or so)
if you plan on upgrading to a 2080 anywhere in the next 2-4 months, I would not buy the 970
if you plan on upgrading at a later date than 4 months it might just be worth the upgrade
You will win synthetic fps benchmarks with sli, but your gaming experience will be better with a single good card.
dual gpu is prone to stuttering and screen tearing. More games are not even supporting dual gpu any more.

I very much like the 9600K for a gaming processor.
You are likely to get an OC near 5.0.

Love the quality of noctua coolers, but the L9I is inappropriate.
It is a downdraft cooler which is not very efficient.
I would, at a minimum use a tower type cooler with at least a 120mm fan.
Noctua NH-D15s would be the best if it fits your budget.

Thank you for the Input:
Plan is to buy the RTX 2080 still this year... i think for 50 euro ill give the sli a try and then sell both 970 cards for the 2080.
Regarding the cooler i've decided to try my CM Evo 121 should that not work i will get the
Regarding the Motherboard im still torn between these 2:
Regarding the RAM im still torn between these 2:
I should prob also get a m.2 (ssd)? any recommendations?
I heard that in gaming these are not much faster than a normal SSD so maybe one just for windows (128gb)?

CM 212 is a popular cooler because it is cheap and modestly effective.
But, I had occasion to have to install one and I do not recommend it.
It is difficult to mount evenly. But, I suppose you know that.
There are some better alternatives.
Your case is a nice one with good cooling and plenty of space for a good air cooler.
If you plan on overclocking, and I urge you to, the cooler becomes one of the possible limiters.
I might suggest a cooler with a larger 140mm fan or one of the twin tower types.
I highly recommend the noctua NH-D15s.
It is fully the equivalent of more expensive 240/280 aio coolers.

I have no opinion on motherboards so long as they are Z390 based.
All will do the job.

On ram, the corsair lpx 3000 ram seems good to me.
Intel does not depend on fast ram.
The lpx is cheaper and is lower profile that will fit with any air cooler.

m.2 is a ssd size format.
It comes in both sata and pcie forms.
I like them because they require no sata power or data cables.
With no budget concerns, the pcie version is much faster sequentially.
But, the fact is that most of what windows does is small random I/o and the sata versions are about as capable.
You definitely want one for windows.
120gb is really too small. 256 0r 500gb.
Space is easiest to manage with one large drive.
If starting anew, I would suggest a 1tb drive for all and add a HDD later.

Another option you might want to consider is adding a 16/32gb optane device.
It is a very fast m.2 drive that can cache your 3tb HDD.,computers,228&sr=1-2
