Trivial performance increase from GTX 760 to 770

[stuperstrong]

I went and bought a: http://www.microcenter.com/product/416548/N770_TF_2GD5-OC_NVIDIA_GeForce_GTX_770_Twin_Frozr_OC_2048MB_GDDR5_PCIe_30_x16_Video_Card

To replace: http://www.microcenter.com/product/419486/02G-P4-3765-KR_NVIDIA_GeForce_GTX_760_Superclocked_ACX_Cooler_2048MB_GDDR5_PCIe_x16_30_Video_Card?ob=1

and ran a couple benchmarks, and I'm only really seeing a 2-4 fps jump in scoring and even getting lower minimums on some of them.

http://pcpartpicker.com/p/3aqIZ Is my build as of now. My CPU is also overclocked a little bit.

Well, I honestly dont know what you are expecting. That like upgrading from a 7850 to a 7870 or something similar. Its an almost identical card with slightly higher performance, and you are getting slightly higher results.

When upgrading a GPU its a good idea to go at least 2-3 versions up. So a 760 to a 780/780ti.

Sounds weird. I would say that 770 is quite a bit better than 760. Can you monitor clocks/temps when gaming? Load?

 

[stuperstrong]

I didn't see my Cpu or gpu jump above the mid 40s at any point. Yeah, I expected a bit better in difference of performance.

I think my Cpu may be bottlenecking it honestly...

 

[FunkyFeatures]

How about the load? Btw, i dont think the cpu is bottleneck, if its overclocked

 

[stuperstrong]

I'd have to try when I get home, I had just tried with gaming for the most part. It's only slightly over clocked (about 8% I think).

 

[FunkyFeatures]

The temps are also quite low. 40 celsius, i would take that as a high idle, but very low load.
I would say gaming should be around 60-75.

 

[jshoop]

even if it isnt overclocked, your processor won't bottleneck a stock 780ti. the upgrade was too little to gain a huge jump in performance. i wouldve gotten another 760, or atleast the 770 4gb so you can sli in ultra without hitting the vram limit

 

[stuperstrong]

My Motherboard supposedly doesn't support SLI and I didn't need 4gb since I have a single monitor at 1080p. Also, the 760 was a return, so I just paid a 60$ difference in card price.

 

[Gam3r01]

If you only spent 60 bucks that was fine. If you went from a 760 to a 770 without a refund THAT would have been bad.

 

[stuperstrong]

I had intended to Sli, but the mobo I
is an issue. I'm currently running prime95, at about 10 minutes in with temps at 49-50c. Ran furmark on the gpu and jumped from 67-69c.

 

[stuperstrong]

I turned my case fans speeds up and re-ran the furmark test for 15min and topped out at 78c that time around... Seems turning them up didn't exactly help me.

 

[jshoop]

that cooler is really good, i would suspect less than 78 degrees on load. And it seems like airflow isnt the reason. What are your ambient tempuratures?

 

[stuperstrong]

I keep my room, where the computer is located, at about 70-72℉ generally. The desktop is behind my monitor due to having to rearrange my desk a bit.

 

[jshoop]

is it sorta in the corner of your room sorta sideways? it might be that the exhaust is staying in the general area and the intake is pulling the warm air back in.

FYI, Furmark was made obsolete around the Fermi generation when Nvidia incorporated GPU speed throttling, specifically when Furmark and OCCT are used. You should try a different stress tester to get a true measure.

When you upgrade from a GTX 760 to a 770, the performance increase should be around 20%. That means that a game running at 100 FPS on a GTX 760 should on average run at 120 FPS on the GTX 770. By the same token, that also means a game running at 50 FPS on the GTX 760 will only be running at 60 FPS on the GTX 770. So set your expectations accordingly. 20% seems like a big performance boost, but in reality it can amount to less than 10 FPS on some of the more demanding games.

It's about center on the wall, under the vent, so it isn't getting any direct airflow from it. Tv is also on the desk with the back facing the front of the computer. The two exhaust fans (back/top) are facing open spaces. the three intake are two on the side blowing the gpu and one on the other side blowing the back of the mobo where the Cpu is.

 

[stuperstrong]

What stress tester would you recommend?

 

[17seconds]

Go for MSI Kombustor, that installs along with Afterburner. It's based on Furmark, but I don't think that there is a BIOS flag to cause the card to throttle.

 

[jshoop]

unigine heaven is great, its very configurable to what you're settings are

 

[jshoop]

also, with afterburner you can set a fan profile, so if you dont want it going over a certain temp you can control how fast you want the fans going. for example my max i want my gpu to get is 80 so at 80 degrees i set the fan speed to 100, and keep a very agressive fan speed down to 65 or 70. below there, i drop the fan speeds so it doesnt sound like a jet when i web browsing

 

[stuperstrong]

I'm in the 70-72 range on Kombuster, but I don't think I know exactly how to set the fan speed thing... I set it up, but when the temperatures raise, it still shows my fan speeds at only 60%.

i found this very helpful when i was using it

 

[stuperstrong]

Seems like every time I get to 70c my card auto drops to 60-65% fan speed... All the settings prior to 70c work.

 

[jshoop]

thats wierd, have you tried reinstalling your drivers? i dont know if thatd be a problem, but your fans should be able to hit 100%
