hello
 
its getting time for a new system for me.
the price difference between 2048 and 1664 core is about double. is it worth the difference?
 
 some thoughts on my new pc. what I have now is a i7 920 @ 3.7. 6 gig ram and a GTX 760 4 gig,
I am thinking about a socket 2011 system with 16 gigs ram and a GTX 970 4 gig. but the cpu clock isn't that much greater than my 3.7 ghrz I have now. is it worth it? will I see a gaming increase. I play at 1080p all the bells a whistles  I like to have maxed out.
 
thanks for your time and advise

    Socket 2011 X79 or X99? The clock speed isn't much of an indicator of performance. Newer generation cpus will have higher performance per core. A 4820K will have much higher per core performance and at a default of 3.7Ghz with headroom to overclock. On the newest games you will likely see a higher average fps.

    A 970's performance will generally fall between a 780 and 780 Ti, so you will definitely see a performance increase.

    As for the difference between X58 and X79, CPU speed is only part of the story; the improved chipset and architecture, not to mention the much faster memory bandwidth, will make a very noticeable improvement.

    thanks for the replies. x99 chipset 5820k cpu not sure about the ram I need to read about that. what about the cuda cores? why such I price difference from 2048 to 1664
     
    thanks again

    6 highly overclockable Haswell cores with quad channel memory will absolutely be a noticeable upgrade in pretty much every facet. You won't be disappointed.

    The difference in CUDA cores seems small because you're comparing the cards as if they were both Keplers. The 970's uses a newer architecture, and has far more efficient performance per core, so it doesn't need a significantly higher core count to have a large performance boost.

    oh ok the different video cards with the different number of core are two different architectures.
    the 970 being the newer of the two? witch is why I didn't see 512bit like I use to back a few years ago. better architecture yes?

    Well if you're comparing the 980 and the 970, they are the same architecture.  So, yea it's 2048 vs 1664, and the 2048 costs a lot more.  Whether it's worth it is up for debate, but I chose no...and just got 2x970s, which would be way faster than 1x980.
     
    Some of the earlier generation cards like the 780ti and Titan had more cores, but the cores in the 9xx series are more efficient, so the card with 2048 cores (or even 1664 in most cases) will beat the old one with 2800-something cores.
     
    As to your system, an i7 920 at 3.7Ghz is still quite fast.  You may really not notice a whole lot unless you really utilize it, but the newer processors are significantly faster.  I had a six core i7 970 before, but I replaced it with a Haswell 4770K.  The processor is faster, but I don't really notice it (the newer one with 4 cores is just as fast at transcoding)...but the platform your processor is on is really, really old.  I upgraded not for the CPU, but for the modern platform with USB 3.0, etc.  
     
    I still do use my X58 and old i7 for Linux, with a ton of memory (24GB though will likely upgrade it to 48GB) and it's great for that job.
