Hey guys, I've seen a lot of questions regarding bottleneck here. I think I know some things about computers, but recent releases in both CPU and GPU made me confuse and I really can't find an answer anywhere, so that's why I am creating this thread. Maybe there are other people in my situation.
So, in short: I own a GIGABYTE GTX 750Ti 4GB VRAM and I intend to upgrade my system. I have at the moment an AMD A8 5500 APU 3.2 Ghz together with 16 GB RAM DDR3 at 800 Mhz, but my system broke and I can't find the guilty component: CPU or motherboard. So I just want to buy new CPU and new motherboard to upgrade my system so it will perform better in gaming. So I think about getting the AMD Ryzen 2700x together with an AM4 motherboard, probably the ASUS Crosshair VII HERO and 8 or 16 GB RAM DDR4 at least 2400 Mhz. Unfortunately I don't have the money to upgrade my GPU, I was thinking about GTX 1070 6GB or maybe even GTX 1080Ti, but at the moment that's too much for my budget (about 800 USD maximum).
Because bottleneck is mostly used to compare CPU with GPU performance so you have to balance these two my question is: Will my GTX 750Ti handle Ryzen 2700x okay or I will have a HUUGE bottleneck and any game I have will run bad? I tried with thebottlenecker.com online calculator to test my future system but they said I will have a huge bottleneck and for Ryzen 2700x is recommended TITAN X, GTX 1080Ti, RTX 2080Ti and other monsters. I understand that these cards work great with Ryzen but these cards have a huge cost and I can't afford it at the moment.
And until I get the money to buy a new graphics card I just want to play using what I have at the moment. And buying another AMD A8 CPU with FM2 motherboard will cost me about 250 dollars and I don't want this. I prefer to save another $ 500 and buy something new, something 2018, not from 2013. Any ideas?
Thank you!

With a CPU that is better than a GPU, the game will run as good as the GPU is capable of performing.

If you have 800USD to spend, perhaps you can fit a GPU in to your budget.

Ignore bottleneck calculators. They are worthless and meaningless A bottleneck depends on the application used. Some applications or games will have more a bottleneck pending on the resources required.

I would upgrade your platform first as the 5500u is really not even relevant. If this is just for gaming, you dont need a 2700x, save some money and get a 2600. it will be within a few frames of a 2700x. Games just done use 16 threads. The unused threads will sit doing nothing.

Also, go for 3200mhz speed RAM. Ryzen scales well with high speed RAM. Running 2400mhz you will leave performance on the table.

Upgrade the CPU/RAM/Mobo. Then when you have the money, get a GPU. The 2060 is a solid GPU that you should look at over a 1070.

Bottnecker is junk science.
There is always a limiting factor in games.
Normally you want a balance between cpu and gpu capability.
One rule of thumb is to budget 2x the cost of your cpu for your graphics card.

Since your cpu/motherboard is gone, you will first be looking at a cpu, motherboard and ram upgrade.
For gaming, I favor the new intel processors, they will have better single thread performance which most games need.

On a budget, I think you would be pleased with a $200 i5-8400.
Your current GTX750ti would work fine, but probably a GTX1070 class card would be a good upgrade.
If your aspirations were to game using a GTX1080ti class card or better, I would suggest a i5-9600K or even a i7-9700K each of which will oc to 5.0 or so.
Your A8-5500 has a passmark rating of 3993 and a single thread rating of 1271.
By comparison, the i5-8400 has a rating of 11630/2336
 


Junk website.

^Better site to determine where performance can be increased.
 


What are you talking about? Tested with a 1080ti the 2600x got 1% fewer fps than the 2700x. Any of the current Ryzen 5's or current i5's will pair fine with any GPU on the market.

https://www.techpowerup.com/reviews/AMD/Ryzen_5_2600X/13.html
 


That's exactly what I would have recommended.
 


So you are saying that there is no reason to get the R7 2700X?

From my understanding, the R5 2600x is a mid tier processor, and the R7 2700X is a top tier processor. And the GTX 1070 is an upper mid tier graphics card, and the GTX 1080 and above are top tier graphics cards. At least that is my opinion.
 


For gaming, there is little reason to go with the 2700x. It offers little to no increased gaming performance. Most games dont even use all of the threads on a 2600, much less the 16 threads on the 2700x.

Mid tier, top tier, bottom tier does not matter. The CPU does not matter that much in gaming these days. Look at the 8400, it is a sub $200 CPU and it gets only 5% fewer fps than the 9900k that cost $500. As long as you get a modern CPU, it will game like a beast.

For a gaming rig, spend your money on the GPU. That is the heart of a gaming pc. Not the CPU.
 
Thank you very much to all of you which wrote to my thread! I really needed some expert advice about this issue from people which already own AMD Ryzen and GTX 10 series and can tell me from their experience! I guess I will have to make some new changes in my future rig and go for a lower CPU but a better GPU. I know that my 750Ti is not able to run the newest games very well and I was thinking about changing this one as well, but it seems that I have to change the GPU first and then think about a budget CPU. The 2600 really seems great for my gaming system, it seems there is no reason to go for the killer 2700x if my primary objective is only gaming. I guess 2700x is suited better for streaming, rendering and so on. I really don't need this, I just want high fps in gaming.
Because I forgot to add this info at my first post: I got for my birthday an ASUS PG278QR monitor, 27", 2560x1440 resolution, 1ms response time, 165Hz OC refresh rate. And I had a basic LG Flatron 24" 1920x1080 60Hz monitor before. My GTX 750Ti doesn't offer Display Port output so I can't use my monitor at a higher refresh rate than 60Hz so That's why I need to upgrade both my GPU and CPU.
So you guys say that 2600 paired with RTX2060 will do just fine? I guess I owe you a cold beer for this one!
 
Here is a review of the RTX 2060. The RTX 2060 may have some difficulty with that resolution.


Unfortunately, tuning up the fidelity to 2,560 x 1,440 drops the frame rate to 45-40fps if left on Ultra quality settings and ray tracing. However, 4K with all the same settings is still surprisingly somewhat playable with the frame rate hovering around 25fps.
https://www.techradar.com/reviews/nvidia-geforce-rtx-2060
 
I don't need Ray Tracing from RTX cards, I have done some research about it and althought it really looks great, it drops the performance to 50% or even more. I want fps in games, not hyper realistic graphics on 4K. If I tune everything to ultra in 1080p resolution and I get at least 70 fps I will be the most happy guy ever. I understand that Ray Tracing and high FPS in 2K or 4K requires a PC of AT LEAST 2k USD, I don't have this, I can't afford this. My goal is to get 1080p gameplay of newest games such as GTA V, Forza Horizon 4, Shadow of Tomb Raider and some more with over 70 - 80 fps in Ultra quality with the cheapest budget possible.
 




Yes you are right! RTX 2060 is newer than GTX 1070Ti and performs better for a similar, actually smaller price. I have seen a lot of testing in games. Now about CPU, is the 2600 enough or I need more? Or could I achieve what I need with less? For example 1700x? I have seen that it's not a huge difference in price between 1700x and 2600x
For a very cheap budget I did last night a small rig online:
PSU: nJoy Legion 600W, which is about 64 $
DDR4 RAM: Corsair Vengeance LPX DDR4, 2x8GB, 2400 MHz, CL 16, which is about 125$
CPU: AMD Ryzen 5 2600X, 4.25GHz, 19MB, which is about 240$
Mobo: Gigabyte, GA-A320M-S2H m-ATX, which is about 62$
GPU: Gigabyte GeForce RTX™ 2060 OC, 6GB, 192-bit, which is about 476$
PC Case: RPC AA000BF, about 20$

Total price: 987$, almost. I said "about" to each price because I have seen the price in RON, my national currency and converted it to USD using Google. So it's not a fixed price. Any changes to this setup?
 


You were the one who stated that you didn't want ray tracing. The GTX 1070 Ti simply doesn't have it.
 


Definitely do NOT get the A320 motherboard. It's just not a gaming board. You won't be able to run fast RAM and your CPU won't get all the power it needs. Get a B450 or X470 motherboard. Oh, and not to mention the 300 series motherboard will require a bios update to be compatible with 2nd-gen Ryzen. Also get fast RAM, DDR4 3000 or 3200.
