How fast a GPU before bottleneck?

Hello experts.

I'm looking at upgrading GPU but I'm unsure how high I can go before it will be bottlenecked too much by the rest of the system. Currently the system is a I5 2500k @ 3,?ghz with a R9 380 4GB. The motherboard is an ASUS Sabertooth P67 (PCIe 2.0 x16).

So, how high can I go without wasting money? The rest of the system will stay the same for now.
 
3.? is a pretty week overclock for an i5 2500K. I have mine overclocked to 4.8 on air. Get it up to 4.5 & you should be good with a 1070 or 80. Also, get the fastest RAM your motherboard can handle. My i5 system is running 1600mhz OC'd to 1866
 
Sorry, I actually meant 4,?ghz. I can't remember how much and I'm not near it atm, but it isn't up at 4,5. I think I'll look at more overclock, faster RAM and then maybe a 1070.

If you're sticking with that CPU & RAM for awhile I think the 1070 would be a good choice for you. Keep an eye on the 1080 prices though, since the 1080 ti launched they will come down.
 
Yeah 1070 is a nice spot. Bottleneck is tough since your target Hz and the games you play matter a lot.

If you're aiming for 60Hz then you'll be fine in the majority of games.
 
4.4Ghz is a fine OC for a 2500k and 1070 will keep you bangin' for a while still if you're at 60hz@1080p. Enjoy your still-awesome-and-great-investment CPU.

That all depends on the software/settings. You can't just concluded when you CPU will bottleneck you GPU or vice vs just looking at the hardware.

The more graphical effects resolution and AA the high graphics card you CPU can run with without being the bottleneck.
The lower the resolution/older, the game the easier it is for the CPU to become the bottleneck
 
As noobferguson stated you'll be fine with a 4.4ghz OC and a GTX 1070 at 1080p/60hz. I wouldn't bother upgrading the system til you upgrade your resolution. I run a 4690k@ 4.2ghz at 1440p with a 1070 and can still max most games at 60hz.
 
Bottleneck it at what?

If you play something like Age Of Empires II HD then any GPU will be bottlenecked by the 6700, because there is so much logic to do and the game is single threaded.

If you play a graphics intensive game using Direct X 12 I don’t think any GPU could get bottlenecked.
 
a 2500K at 4.0+ghz is fine. People over-exaggerate bottlenecks. You could buy a 1080Ti and it will scream. If your hitting high frame rates than just apply downsampling (DSR).

The only time I question someone's CPU is when it's so old it's dragging down minimum frame rates. Minimum frame rate is almost entirely up to the CPU. The GPU plays a big part in it but for the most part it's CPU.

This is very true. These days it all depends on the game. Most won't really be your cpu unless your running high refresh rates or maybe some vr titles.

The only time that I saw a real bottleneck was when I thought that it would be a good idea to break out my core2 duo rig to test an original titan. Fucking valley throttled the entire time. No way is an overclocked sandy bridge going to do that.
 
all cpus bottleneck, get the fastest GPU you can afford and then upgrade your CPU a year or two later, again getting the fastest CPU that matches your intended use
