Specifically looking for experienced with westmere xeons that are overclocked or 970/980x i7s. My dad's x5670 is running at 4ghz and he has plans to get a gtx1080 to go with it. Benchmarks show it comparing favorably to newer CPUs but I was hoping someone here was actually running a similar system with some real world experiences.
I don't think the cpu should be a bottleneck at 4ghz but you never know.
Hello there, the biggest concern is the single threaded performance which is waaay higher with modern CPU's nowadays compared to the older ones even if you overclock them, plus the instructions supported by them.
I believe someone had the same CPU? @Lemming1970 was that you? He upgraded his and experienced a much better performance altogether if i remember this correctly.
I went from an Xeon X5670 (originally an i7 920 O/C to 3.6Ghz) which was over clocked to 4.2ghz(6 core-12 thread). The performance increase from that to an i7 6700k o/c to 4.6ghz(4 core - 8 thread) was massive. Much more than I was expecting TBH.
The system had, had a few GPUs over the years. GTX 285 SLi GTX 285 AMD 6990 GTX970 SLI GTX970 GTX980Ti ( slightly less peak performance over SLI 970's but much better averages)
Single core performance is key in VR and older cpus even fast ones don't have that key performance. I wasn't to bothered as my system had been running everything I threw at it for the last 6 years. Even monitor gaming saw a big increase in performance over the Xeon 5670.
I think you'll see more of a performance boost getting a new CPU/MB/DDR4 than you will getting a GPU if you already running say a GTX980. It's not just the clock speed but what it can do in each cycle that affects performance overall. You'll also gain USB 3, SATA 3 and M.2
Thanks lemming. Did you migrate the same GPU from the 5670 to the 6700K or was the new system a ground up rebuild? Single core geekbench score is 3023 (32 bit only since I am using the free version). Newer CPUs seem to get about 20-30% better single core scores. Of course the 6700K does even better than that. Looks like that chip has the best single core performance we've seen yet.
If you do want to stay with a 980X, as long as you overclock it to 4.2 Ghz you will get pretty great performance in VR with at least an Nvidia 970. That is what I have - and I still have a DK2 - which is much clearer now with the Oculus Debug Tool setting pixel Override at 1.5 I run DCS World and War Thunder

Cool. Well I'll have to start him off with the 5670 since there's not a chance he'll get the 1070, rift and build a new machine, but I guess the writings on the wall. Black Friday cpu/mob combos will be of interest for him, especially since he's interested primarily in racing.

Huge difference in Project cars with the 6700k over the X5670. In VR or on a monitor.

I am upgrading from a 4790k to a 6900k should have my 6900k in July... I primarly play Pcar
Hum... Is that really worth the time and effort? A 6900k would be an "enthusiast" chip, so it's main draw is more cores (8?). Does/will pCars make use of them?
edit: just checked myself... by default, it's HIGHLY single threaded, but you can use some commandline options to change that "-dx11mt -pthreads 4"
BUT... overall usage only went from 13% to 22% on my system. From 1 maxed core and 11 near idle cores to 1 maxed core, a handful of moderate usage cores (40% range) but still at many idle cores.
FYI: In case you didn't notice, I have an i7-5820k paired with two Titan Xs in SLI, running across three monitors at 6480x3840 resolution and whatever settings it gave me on first run (played it before, but reinstalled windows not too long ago).
So, I think an i7-6700k would out perform the 6900k, only because it has a higher clock speed for that main thread in pCARS. But that said, I don't see upgrading from a 4790k to a 6700k particularly worth the time and effort... but that's just me.
