    Hey all,

    So pending delivery of a new stick of RAM I'm preempting the worst and assuming my motherboard is dead...

    ..so it would be upgrade time.

    Looking at my options I know I'll be getting a Gagabyte or ASUS ITX sized GTX970 4gb which Im sure will outperform my previous GTX460 SLI setup, but what Im wondering is how much effect CPU power is likely to have on my experience?

    The build was primarily a HTPC so media playback is still a large proportion of this but I know CPU wont offer too much more for me here, so with various generations of he 1155 socket now in existence I have options to consider on whether I buy old or new, mid range or top end etc, and I wondered what impact I would actually notice?

    Ie lets say my base build is;
    Asus Maximus III Mobo
    8GB RAM
    4GB GTX970

    What difference would say a 2nd hand 3570k over a new i5 4790k offer? Likewise how much would I notice between a 4790k or maybe a second hand i7 4370k etc, would there by any real world difference I would notice or really do CPUs not give much significant impact nowadays given their performance capabilities?

    Thanks
    Grangey

    Update,

    The new RAM confirmed the mobo is dead. Upgrade is now without doubt on the cards and something I'll want to move ahead with pretty sharpish so appreciate all your input in this.

    That said.. Im out of the loop on release cycles... I wouldnt want to buy this lot to find out that if I had waited 3 weeks NVidia will have brought out the gtx10 series, or intel a new raif of processors. Obviously I know there will inevitably be some out sometime after I build this but how long would be good to know :)

    depends on what you are doing i guess. i7 only really good over an i5 for encoding and high level cad etc. i7 seems overkill for gaming offering little for the extra hit.

    there is a new series of CPU coming out but they didnt offer much over the 4790k which i have.

    having said that, i just read an OC thread about this chip and a guy got an extra 20fps in bf4 after overclocking his CPU more.

    what do you want to do with the PC?

    my pc is a similar spec to what you seem to be after. (btw, the 4790K is an i7)

    you could always look at benchmarking sites to compare CPUs:
    Intel Core i7 4790K vs i5 3570K

    toms hardware had the same question:

    we're going to see over the next two years (including this year) games take advantage of 8 core processors like the i7 (Witcher 3 being one game) So the i5 will be better for the first year or so but the i7 will have more longevity as cpu

    For years I have been a champion of the i5 over the i7 in terms of gaming and indeed my 4.3ghz 2500K from feb 2011 is still rocking it with the big boys....... however....

    I do think this may change going forward.... and indeed I am in a similar quandry with my next upgrade (6600K or 6700k).

    given how long cpus last before becoming obsolete (ie will be close to 5 years for my current chip for instance, and it has covered 3 GPU replacements) I think it is maybe worth pushing the boat out. My logic is that the chances are my next cpu will be taking me up to and beyond 2020 so what is an extra 100 quid or so?.

    The only reason i am upgrading in the next 6 months to be honest is not enough USB3 and my mobo does not support SLI, pure CPU wise it COULD last me another 18 months easy imo.

    OP, before you go ahead and buy a mobo and CPU. You know that the CPU's you posted are two different sockets don't you and both aren't 1155?

    If it starts with a 3, ei 3***k it is 1155, it it starts with a 4, 4***k it is 1150. I just didn't want you to but the wrong gear :)

    Hi Guys,

    Thanks all for your input. I hadn't actually realised that the new consoles are 8 core, and sadly todays input came a little late as my shiney new 4690k has just arrived. Having known this I may have been swayed to splash out more, but with that said I think Im more inclined to stick with the 4690k and see how it fairs over the next couple of years. Im a great fan of SLI'ing and always viewed this as my first path for an upgrade, but if games do indeed change in the next few years to become far batter and utilising 8 cores for far more optimal gaming I'll suck up the mistake and just change the CPU then I think, gives me a nice excuse to upgrade anyway :facepalm::clap:, but with that said given just how long the current gen of CPUs have been available and with the load put to the GPU for our pixel porn over cpu, I'm questioning how much impact an extra 8 cores could make. Lets be honest, the current gen of GPUs already match and exceed what's available on consonsoles so whilst these might need the extra processing power, how much our future GPUs may need this will be interesting to see.

    Anyway, new build will be together at the weekend so bring on the fun :)

    indeed, I think multithreading WILL become more of a thing, but hell, the current consoles are a joke imo (a joke with a nice amount of ram mind you). regardless of if your CPU will be a slight bottleneck, it is not going to be a showstopper. :)

    ps a little segue, when you look at what some of the games are like on the medium range laptop hardware that are the next gen consoles, when you look at games like forza 6, uncharted 4, horizon zero dawn etc it makes you realise what the hell games would look like on our high end PCs if they were as optimised to the metal as console games.

    I really hope DX12 helps realise this dream!

    What about the 3930K or 4930K ? :p

    At OP - your 4690K is better than the console's CPU so I wouldn't worry - plus you can always stick a 4790K in there at some point in the future.

    I think there are only a couple of games that show a benefit of having more than 4 threads - didn't stop me from buying one though :blush:

    C*** :laugh:

    They are enthusiast chips, the OP isn't going for one of those man. I didn't feel the need to sit down and list every cpu and socket available on intel, the price alone would have put him off ;)
