Hey,

I received a new 1080 after picking one up on a black friday sale. This was to replace an aging 7970 that was in the rig before (see this thread for the rest of the rig details https://forums.overclockers.co.uk/showthread.php?t=18755762). I removed the ATI drivers completely and then installed the new graphics card, installed the latest drivers from nvidia and then ran a few test games. The results were initially relatively underwhelming and I was getting some fairly noticeable framerate drops on 4k with high settings. Am I just being too keen on the settings and expecting too much? I ran 3D mark through on the machine and got the following:

http://www.3dmark.com/3dm11/11773013

The physics seemed to be a lot lower than other single 1080s in the 3dmark thread, is this just my CPU bottlenecking now? Any advice would be greatly appreciated! Does something thing like it could be wrong or is it just a case of getting the right configs for games rather than just bunging most of the settings on high and hoping for the best!

Many thanks in advance.
 
Hey,

Thanks for the comments so far. The CPU is OC'd to a (seemingly, prime95 test etc with no temp issues) stable 4.1 currently (which is what the 3dmark was run against). The question about the GPU clock is a good one...I hadn't noticed that at all! What would be the best way to check what is going on there? The card spec should be:

Core Clock 1657 MHz
Boost Clock 1797 MHz
 
Get Gpu-Z and run it, click the sensors tab and it will show your actual GPU clocks in real time, if you have dual screens, you can have it on one while you run a bench on your main screen, otherwise enable the Log option at the bottom of the sensors screen in Gpu-Z.

With that bench you need to use the graphics score when comparing GPUs. Having said that the graphics score is about 3x higher than a HD7970 would get. So no problems with the 1080 performance.

You could do with getting your CPU overclocked to about 4.3 or 4.4 as this will also improve things a little bit.

A 1080 is not bad @2160p but you have to turn the settings down a bit.
 
You should easily get 4.2 on the 3770k even if you have a fairly standard cooler. I'm at around 1.176v on mine. You shouldn't need more than 1.2 for 4.2, or very close to if above.

I have a Xeon E3 1230 V2/Core i7 3770 with an FE GTX1080 and the CPU bottlenecks in the newer 3DMark tests.

Run Timespy and see what you get:

If you get slightly better than my score you are CPU bottlenecked.

Personally I would not worry too much as long as you get decent framerates in the games you run.

Remember even for a GTX1080 4K is still quite a load,and some games can still have performance drops even on the latest hardware.

Try dropping down the settings or the resolution - do you have the same kind of performance drops in the same parts of the games?? Then you are most likely either CPU limited or the game just has crap performance at those points.

Sometimes a game will have crap performance at some points even if you are using the fastest card available.
