Upgrading to 1080 ti with Xeon e5 2699 v4 a bad idea?

[RickytheGeek]

So I have a 1070 right now and have determined that it isn't really being bottle necked because I tested it with a more gaming CPU system and it ran games at the same FPS, would upgrading to a 1080 ti be a bad idea and not yield an improvement? Thanks for any insight into my issue!

The 1080 Ti will bottleneck severely, the clock speeds just aren't up to scratch.
Time for a CPU/mobo/RAM upgrade. 😛

it will bottleneck the heck out of it if the games you play only use 1 to 2 threads. Even so, clock speed is still king. Looks like 1 core can boost to 3.6ghz so that isn't super bad. That is one very expensive chip ($4000) to play games on. I hope you are doing stuff that actually needs more than 4 cores.

If you are using Apps that need CUDA than the 1080ti is a good upgrade, otherwise no point in moving past a GTX 1070.

Incorrect, games are quickly becoming very multi-threaded, so in that aspect clock speed is not still 'king', it's just that in this specific case it isn't to a level where it could be considered capable of keeping up with such a card.

Yeah "Becoming" is the key word. They are not yet. Hence why the i7 7700K is faster than Intel flagship 10 core when it comes to gaming. Looks up benchmarks using both the 7700k and 6950X. You will find the FPS to be the same and in many cases the 7700K is higher because of the ram.

??
I never said that many threads would be utilized.
Compare the i5 and the i7 for example.
The i7 is the prime candidate atm, the i5 is not quite up to par in AAA titles.

Get it. The 1080 ti is a beast I have it on my 3770k and beat any computer without a 1080 ti or SLI'ed

Something that hasn't been asked or discussed yet is what resolution are you gaming at? Many times the resolution will create a bit of a bottleneck now that it's expanded from 1080p to 1440p and 4k. The 1080ti is more for 1440p/4k and may prove to be more gpu than games need at 1080p or lower resolutions. It also depends on the game, skyrim or witcher 3 with additional mods to improve graphics details like enb or godrays will put a gpu through its paces. Cs:go will not.

A bottleneck exists when either the cpu or gpu is severely limiting the other. This depends on the game, the resolution, graphics settings (low/med/high etc). When any of those things change the bottleneck situation may also change. A cpu like a ryzen 1700 may exhibit lower performance at 1080p vs an oc'd 7700k. At 1440p or 4k the bottleneck may be eliminated as the higher resolution puts more work toward the gpu and the two balance out.

Check the games you're playing against benchmarks for the gpu you've got. If you're trying to get over 60fps but only getting 50fps and in that particular game the 1070 is only capable of 50fps then a stronger gpu would likely be a benefit. There's no one size fits all answer, it changes game by game and taking into consideration med/high/ultra settings as well as resolution. If the game is more cpu dependent then the lower clock speeds of the xeon will impact performance some, the turbo boost puts it almost 1ghz slower than turbo boost of a 7700k. That's not a small amount, the 7700k per core is 25% faster.

Hello synphul and others I will be gaming at 1080p because I honestly can't tell much of a difference to higher resolutions and would just like to get super high FPS with decent visuals.

Do you have a 1080p 144hz monitor?
It'll be fine if that's true, otherwise you might want to invest in a 240Hz 1080p panel.
The difference is small 144 to 240Hz, but it's there.

A 1080ti would likely be bottlenecked at 1080p in most games. For higher fps you really need a newer cpu with faster clock speeds and higher processing power (ipc) per core. The ipc generally improves with each generation. Not many games are going to take advantage of 240hz. It's really game dependent. With the fastest desktop cpu (7700k) the 1080ti was capable of 190fps on mass effect andromeda. Ghost recon wildlands on the other hand, the 1080ti couldn't break 130fps. The results are for a specific msi 1080ti gaming x card, not a reference 1080ti.

Have a look at some of the results. It's also worth noting that while yes the 1080ti is 'the fastest' average, there's also a much larger spread between the 1% lows and extreme lows vs the average fps. The wider the gap the more it may appear to 'stutter' as it fluctuates. A dip from 60fps to 55fps isn't as noticeable as a dip from 190 to 122 or 109. Other cards ultimately average lower but they only dip around 20fps rather than 70fps.

With your cpu I'd expect fps to be a bit lower since your cpu is significantly slower. The 1080ti is a great card, I just think at some point there are diminishing returns at 1080p especially when it's not being paired with a high end gaming cpu. Your cpu will play most games just fine and has enough cores to handle thread hungry games like bf1 but it's still slower. In a number of games the 4790k loses out to the 6700k/7700k which are 200-400mhz faster by around 10-15fps.
