Will a new GTX 1070 fix my issue? Or am I bottlenecked at the CPU?

post #1 of 13
Thread Starter 
I have an i5 2500K, GTX 770 2GB, and 16 GB of Ram.

If I dual display my two 1080p monitors (23" & 42") I get severe FPS drop and unwatchable movies/tv on VLC player via 42".

Likewise, if I'm playing a video game (Dota 2 max settings) on 23" and use a dual display with a youtube (or any streaming service) on the 42", I get a lot of FPS drop (120 down to 50 fps) and lag on the game.

I thought for sure it was the GPU, but I did a side by side of Techpowerup GPU-Z and Task Manager and the GPU load wasn't even hitting 50% while my CPU was between 93-98%. It would never go to 100%.

My question is does that tell the full tale? Do I just need to upgrade my CPU to use dual monitors or is the real issue the GPU?

Or is this a driver issue/settings issue?

Do you use evga precision x? It does seem like a cpu bottleneck. Your gpu usage should be much more than 50% unless your capping your frames.

Run like MSI Afterburner with the display monitor open on a side monitor and see where your bottleneck comes from. But with your CPU running at near 100% I think thats your issue right there. As stated above, your GPU regardless should still be way above 50% usage.

Sounds very strange to me honestly.

50% is the absolute max so maybe you're right. It goes even lower than that.

I didn't know about evga precision x but I'll take a look. Will it help?

I'll try when I get a chance. But with dual monitors open, one with Dota 2 and one with a 1080 stream, I get very low FPS.

But If I dumb the stream on the monitor down to 480p then my Dota 2 FPS increases.

This is whats strange to me, I run multiple monitors also and never had my GPU not max out (but I also never had an issue with my CPU going near 100%). DOTA2 is much more CPU based then GPU based if I remember correctly, Do you have any other graphic intensive games that you can counter-weigh the DOTA2 testing too? Like an MMO or FPS, see what you monitor through on DOTA2 then try the same thing on a more graphic, less CPU heavy game and see what happens.

Also, would you be able to test this by just running one monitor with the other completely unplugged from your computer? Keep like MSI afterburner monitor running in the background, run a game for a little bit then just go back and look at the charts. See if you are still getting that bottle neck anywhere just off of one display.

Yes I'll give it a try completely unplugged when I get home. I have a batman game on steam I could try I think that one is pretty intensive.

I'll have to try a couple different scenarios with and without the 2nd monitor.

is your 2500k overclocked ? TBH 2500K is a wack CPU if stock, it even bottlenecked an overclocked 7870 in my previous rig. But get it past 4.5GHz and it's like a new life. 98% cpu is high. I got mine at 4.9GHz and paired it with ddr3 2133, it didn't bottleneck an oc'd GTX 980 G1.

Funny you asked. I actually had it at the stock because of previous blue screens and thought OCing would help. I put it to 4.5ghz yesterday to test and still 98% with Dota 2 and second monitor + stream.

Some members have recommended MSI afterburner, as long as you have an app that reads the gpu/cpu accurately when you are playing the game in real time. Rather then alt-tabbing out of the game to see the system usage.
