question for experts do i need cpu and mobo?

azzurri · May 21, 2017

Hello guys,

First of all i love this forum and the website. It helped me alot of times in the past. The community is very mature and extremely helpfull in my opinion. Anyway i have been wondering about something for a while now and i thought maybe i can finally get a good answer if i post it here.

my specs:
- asus1080ti founder edition
- intel i7 - 3770k @ 3.50ghz
-16gb ram
- a very old motherboard (p8p67 deluxe) https://tweakers.net/pricewatch/271547/asus-p8p67-deluxe.html

I'm really wondering if my cpu and my motherboard is holding me back. My pc is acting up somethimes. I have a htc vive and its not really performing as it should i have the impression. Or maybe its just me.

So my question is do i need an upgrade for 4k gaming and my htc vive or is this good enough. If i need an upgrade what do u suggest?

Thx alot in advance

azzurri :

Your 3770 will struggle with the vives requirements. try to oc if you have a decent cooler as you have a motherboard and cpu that support it.

Gam3r01 · May 21, 2017

Your 3770k, while older, shouldnt really be the limiting factor here.
What isnt performing correctly? What is your graphics card?

Yamitime · May 21, 2017

Your motherboard could well be holding you back as its pci-express sockets are version 2 and that cpu is version 3 like the graphics card.
BTW That Cpu you have is powerfull still 4 cores 8 threads and will clock to 4.2ghz on air easy.

A Motherboard based on the z77 chipset will work wonders

It has been shown time and time again the 2.0 interface vs the 3.0 interface does not have an impact on performance.

looks twice as efficient to me? especially on high end graphics cards that may move data faster than the 2.0 .

"My pc is acting up somethimes."

Until you figure out what that problem is, spending money on new parts is not a good idea. What if you bought a new motherboard and it turns out the problem is not the motherboard?

Have you tested your computer with other tools or games? My starting point is always 3mark. If my score on that is way off then I know there's no point in trying something else until I fix the issue.

edit: Even with a new CPU and that 1080 Ti, 4k gaming isn't going to be a piece of cake. This stuff, 4k gaming/VR, is still in its infancy. It's not a comparable experience performance-wise to 1080p or 1440p gaming. The tech for those lower resolutions are mature now, which is why you can get such rock solid performance at that level.

Gam3r01 · May 21, 2017

Twice the bandwidth for cards that cant fill the bandwidth of the 2.0 slot in the first place. Dosent matter how wide the lane is if the card cant use it all.
Specs are misleading, dont take them at face value.

I have a vive and the pc running it is a 3770k and runs it fine but it is on a z77 chipset that fully supports the i7 3770k .
The graphics card i use in the vive system is only a r9 290x and its butter smooth .
This chap has a good system minus the motherboard.
Just my 10 cents.

azzurri · May 21, 2017

very interesting to be honoust so my cpu is strong but not really being used to its potential?

azzurri · May 21, 2017

Eh i have another question i "think" my cpu and motherboard are socket 1155. I can hardly find any motherboards for it on my usual webstores. It seems to old. ???

Yamitime · May 22, 2017

Look for any board with z77 chipset.
Asus z77-a
Gigabyte sniper m3
Plenty boards.

Kritonios · May 22, 2017

Hello, I think it's obvious that your system is very powerful. Any kind of upgrade in terms of cpu gpu or mobo would certainly be a waste of money. Your processor can keep up with the latest games in 4k perfectly. There is no need for an upgrade. And even in the future when it will start becoming the limiting factor you will be able to overclock thanks to your motherboard. I don't see why you believe that the mobo is a problem.

azzurri · May 22, 2017

whats special about a z77 mobo?

azzurri · May 22, 2017

Btw thanks u guys for the answers. Really appreciate it.

Kritonios · May 22, 2017

azzurri :

Your mobo is p67. Z77 motherboards are theoritacally better. I mean it depends on the user. For example, z77 supports usb v3 whearas the p67 doesn't. But that is very specific and such features don't matter for gaming. Generally the differences among chipsets vary from overclock capability to number of sata devices support etc. Now, the important thing for you to know is that both support overclock and both of them are designed for 2nd and 3rd gen processors

madmatt30 · May 22, 2017

^ that p67 has USB 3 mate - in fact its probably the best non z series socket 1155 board there is.

Should be not a singular issue running the vive at all.
4k gaming , a single 1080ti will hold that back fps wise more than the rest of that setup.

By all accounts replace the board if its faulty (if you can actually find a viable replacement nowadays)

Otherwise no , there's nothing that needs to be done there.

Yamitime · May 22, 2017

The p8p67 deluxe was designed for a second generation cpu . Your CPU is clearly a 3rd generation cpu but they implemented the final bios to support these, then stopped producing the motherboard . The pcie ports on the p67 are version 2.0 .Your cpu has 3.0. Your GFX is version 3.0 too. The later motherboards (z77) for that Cpu allowed for better and faster performance as they were designed with it in mind.
Now I apologize to any one who disagrees but the facts are online including benchmarks and can be compared etc .
I'm in no way trying to tell the chap to upgrade his board I just want him to have the FACTS and not just opinions.

PCI Express 2.0 x16 is the equivalent of 3.0 x8. https://www.pugetsystems.com/labs/articles/Titan-X-Performance-PCI-E-3-0-x8-vs-x16-851/ and other benchmarks prove that Gam3r01 is correct.

Yamitime · May 22, 2017

GhislainG :

This is a quote from your article :-
At this point, we would say that if you are using a high end video card like the Titan X (Pascal) or possibly even a GTX 1080, it is probably a good idea to try to use a PCI-E 3.0 x16 slot - especially in multi GPU configurations. Depending on the applications you use it may not make much of a difference, but the fact that we saw a 10-30% drop in performance with x8/x8 compared to x16/x16 in a couple of our tests just goes to show how large of a difference it can make in certain situations.

madmatt30 · May 22, 2017

Yamitime :

Yes but thats with a dual gpu configuration when the slot bandwidth is halved.
With a single gpu running at PCI-E 2.0 x 16 there is virtually nil difference.
AMD hadn't a single AM3+ board out with PCI-E 3 until the ryzen release.

No actually they say it for any configuration but add especially . The chap is running a 1080 ti and you still want it on that old chipset? A 1080ti pushes as much as 2 older cards so its relevant .

Look I cant spend all day correcting you but am3+ boards with pcie 3.0 before ryzen = https://www.asus.com/Motherboards/SABERTOOTH_990FXGEN3_R20/specifications/

Are you using an old version of the internet?

GhislainG · May 22, 2017

PCI Express 3.0 will be slightly faster in some games, but is the expense worth it? http://www.guru3d.com/articles-pages/pci-express-scaling-game-performance-analysis-review,1.html (you can jump to the last page if only interested in the conclusion). Here'a another interesting test: https://www.techpowerup.com/reviews/NVIDIA/GeForce_GTX_1080_PCI_Express_Scaling/ Check PCI Express 1.1 x16 vs 3.0 x16; the difference is not as high as you may expect.
