GTX 1080 Bottleneck

[mentos514]

Hey guys,

I decided to give up on crossfire (2x 290) I.e battlefield 1

Took the plunge on a great deal for a GTX 1080. My question is I decided on a new card versus upgrading cpu and mobo. I'm still on my trusty 2500k. Will this Bottleneck my card? Will I see much of an improvement in games?

In games where Crossfire is broken, yes you'll see an improvement. In games where Crossfire works and scales well, you can already run into bottlenecks with 2 R9 290s on your 2500K. To be honest the 2500K is fine for 60fps today, but unless you're OCing it to 4.5GHz+ you can forget about high fps gaming on it with modern titles, especially BF1.

Your 2500k will be a bottleneck in Battlefield 1 multiplayer. In most other games, you will be fine.

290 crossfire requires more cpu resources to operate, compared to a single GTX 1080. Add to that the fact that Nvidia's driver has lower cpu overhead, even when comparing single cards, which results in you being in a whole different world of performance.

Even with DX12's lower cpu requirements, going from two cards to one, will help for sure.

I have uploaded about 100 benchmarks on my channel if you are interested (spicy wallpapers alert), with my highly overclocked 2500k and GTX 1070 @ 2000/9000 which should be like 10-15% slower than a 1080. I still did get some cpu limits at 1080p, but overall the system runs great. Even for 4.3Ghz which is my ordinary 2500k everyday speed, I still get 60fps on all games.

Actually I am benchmarking my Lynnfield i7-860 these days, with the 1070 and it still does a pretty decent job.

Not a fan of multiplayer games however, so I cannot really tell you what to expect in BF1 MP, but I have a deep trust in Sandy.

My 4.6Ghz 6600k bottleneck my GTX1070 in some games, yours... defenitely even worse.

Try and get 7700K class CPU.

Battlefield 1 loves many cores. It's one of the most CPU intensive games around and scales very well to 6-8 cores (in multiplayer, the single player is irrelevant yet still used as a benchmark..... but I digress).

This is a perfect time to upgrade your 2500k since the Ryzen R5 was just released today. You'll be able to get a 6 core / 12 thread processor for $250 which is ideal for games like BF1 and other multi-threaded titles..

I can run Handbrake on my 8c/16t 1700 and still play BF1.

thanks for all the replies and data to sift through!

i'm OC'd to 4.5ghz but I too think it's time to move on from this old workhorse.

i'm a little torn though because I can only upgrade one of two ways:

1. cpu/mobo/ram

2. monitor.

I'm currently using a 27 inch asus mx279 monitor.

What would be the best direction to improve my gameplay?

option 1 or 2?

You could drop an i7 in for more threads...?

For how much 2600/2700k/3770k's are going for its not worth it. They have retained really high values. I'd rather spend just a little more and get a fresh Ryzen build before I'd spend out on an unlocked LGA 1155 cpu
