    i5 vs i7

    I decided since Driveclub and other games are delayed until next year not to buy a PS4 at launch so instead I am thinking of using the money for upgrading my PC, mostly the CPU and motherboard.

    This time I am not scrimping on the board like I have in the past, for which I paid a price later on when I wanted to upgrade certain things and add more hard drives. So I am thinking of the ASUS ROG Series MAXIMUS VI HERO which costs around £160 and has all sorts of nice features. No point buying a board worth more than the CPU.

    For the CPU I am going Intel but cannot decide on i5 4670k or i7 4770k (Haswell 1150) obviously the i7 has more threading but is it really worth it? Is it noticeable in video games which is the primary point of this computer.


    Is it me or has RAM gotten more expensive? Pretty sure I bought my 8GB RAM fro about £40 a couple years ago and now 4GB costs that much.
    I was going to buy 16GB but since its another £140+ I think it will stick with the current 8GB I have.

    As far as I know an i7 provides very little in terms of gaming benefit over an i5. I say go with the i5 and use the cash you save on a few extra games

    It's possible that the hyper-threading of the i7 may pay off in the future if more cores start being utilised due to the PS4/XB1.

    If I was a pure gamer I'd stick with the i5. Unless you're doing a lot of media editing or development work then having an i7 is pointless.

    It's not pointless for games that are CPU-intensive.

    A high end i5 (like the one he posted) would eat through any game's CPU dependency easily.

    And an i7 even more so. The i5 would do fine, I'm not saying it wouldn't... but that doesn't mean the i7 won't give you better performance... because it will.

    Difference is negligible

    I didn't even look at the i7 in the OP. It would definitely be a waste of money, then. He can spend the difference on a better GPU, if anything.

    The thing is with games is that unless you're playing something like Civilization you're not going to see any difference at all. For me I've tried a top end i5 and the i7 I got for programmes like 3ds Max and other intensive CPU apps and the difference was MASSIVE, but in games there was zero difference.

    It's the reason why I said that for gaming getting an i7 is pointless. Until the game engines start implementing on-the-fly multicore processing then getting anything more than a Quad Core is not worth it, especially with Hyper-threading.

    I think I will go for the i5 4670k and spend the money saved on a Noctua NH D14 cooler. Seems like a beast, will have to measure my case to see if it fits first.

    http://www.aria.co.uk/Products/Compo...roductId=56049

    Total price would be £395 for CPU, motherboard and cooler.

    Thanks for the help and info.

    When more devs begin fully utilizing these cores... we'll all be better off. >_>

    Depending on your Mobo you might have to go with Low Profile RAM if you use all 4 Dimm slots as the Cooler will cover the 1st Dimm slot

    You'll definitely need low profile RAM for that HSF, similar thing happened with my Arctic i20 HSF.

    This is the RAM I already got and thinking of re-using, is it low profile?

    http://www.corsair.com/cmx8gx3m2a1333c9.html

    I will take some proper accurate measurements tomorrow when it is daylight. Noctua give details schematics of the cooler.

    44mm clearance bottom of fan and the base of the cooler

    Low profile RAM is when it's almost the same height with the heatsink on the RAM as it is without it, basically just a few MM taller. non-low profile RAM is when the heatsink just seems to be friggin' huge on top. Here's the RAM I use:



    As you can see because the height is almost the same as without a heatsink it's "low profile" so you won't have a problem putting it underneath a CPU's HSF. Also to quench the myth on gaming RAM vs low profile difference, it's zilch, there is no difference so don't buy into the "gaming RAM" side of things, just get low latency low profile RAM and you'll be sorted. 8GB is what you should aim for.

    I did the measurements and the Noctua NH D14 will fit but its going to be close because of the foam on the door panel.
    Then I saw this video which confirms what I was thinking.

    Looking good Keefy. I was going to get the Noctua cooler but it was too big and would've meant removing the heatsink from my ram sticks plus it was heavy and I didn't want to put strain on my motherboard. So i ended up doing a custom loop

    Just ordered some sound proofing for my case, it already has some but not in the roof an more is always better, I wan this to be as silent as possible.
    Nowhere locally has it so had to send off for it which means delivery added to price

    The scan website is horrendous to use and login to.

    You should've gone for an Antec P280, not only does it have oodles of space but it's seriously quiet!

    I have the i74770 with stock cooling that sucker gets hott, like 60°c when converting video.
    I also have an i5 something 3.0GHZ and performance wise is just as snappy, games will run fine.


    Go with the i5 and spend the difference on cooling.

    PS4 has little to no competition.

    I was eyeing that case up but at the time I didnt have £100 to spend on one.
