    Question Ivy bridge i5 worth the extra £ for a Ivy Brige i7

    Hi Guys

    I planning a new PC build and I was wondering if you guys could help. At the mo I thinking of getting the i5 Ivy cpu but should I be looking to buy the i7 what would I really gain from it, as I only really play games and I tend not to do any video editing of Cs'ing, so should I just stick to the Ivy i5 because I don;t think that I would need anymore ummff?

    Many thanks

    In your case, the extra cost of an i7 is a waste of money. I've got an i5-3570k having considered the i7 as well and I use my machine more heavily than it looks like you plan to. CPU performance has not been an issue for me, nor do I expect it to.

    Many thanks Badass

    I thought as much But thought I best to get other peoples views on this before spending more money on something that I might not really use -- he heh instead I can put the money to a more deserving need. :-)

    Many thanks for the quick reply too

    I feel relatively qualified to answer this, as I have three machines - two i7 3770ks and one i5 3570k. General day to day usage, you'd be better off spending the difference on an SSD. There is zero noticeable impact between the upgrade day to day. Also in games, they seem to be mainly GPU bound, except for perhaps Skyrim, but the performance is way over 60fps to care. Other games I see no difference whatsoever. I have been doing a lot of vid converting for my Raspberry Pi lately (don't want to pay for the MPEG-2 codecs) and there is a reasonable difference. Opening stuff like Photoshop - again the SSD makes the bigger difference. Buy that instead, spend it more on graphics (if gaming is your focus) or save the cash!

    If you are not overclocking then have a look at Cat's recomendation in this thread.

    Xeon E3-1230 V2 seems to get you i7 prformance at i5 price. Best of both worlds if you are not overclocking.

    for a Xeon you need a adequate motherboard (not one with a B75 chipset). Read my reply to the quoted thread.

    EDIT: I beg your pardon, looks like Asus did managed to get a Xeon working. The MB spread sheet says the following : *Since Xeon CPU is not desktop CPU model, some feature may not able to work on this combination. For detail, refer to support.asus.com.

    For gaming i5 and i7 perform pretty much the same, give or take 3 fps. The only advantage the i7 has is hyperthreading which is used in rendering videos, converting videos and so on. The i7 is more future proof, games will start to take advantage of hyper threading so if you can get the extra money then future proof your pc. If you can't find extra money get the i5 because you don't want to go budget on any of your other components.

    That is still a good point to double check the motherboard you want does support the 1155 socket xeons.
    I had a look at a few motherboards (Gigabyte, Asrock and MSI) and they all seemed to support the xeon with the latest BIOS's.

    get an i5 - by the time you will worry about `only having a quad core` , you`ll want to change the whole rig anyway. and get a nice shiny SSD

    Made a similar choice recently. Even though I was building a quite high end machine I still couldn't come up with a justification for the price hike and spent the money elsewhere. My thinking was by the time gaming and alike need more than 4 cores It'll either be a cheap upgrade to get a 2nd hand i7 or I'll be building a whole new rig anyway.

    from when SB first came out but its still true - in some games the i5 is actually FASTER

    Could be because of the way the i7 works? It emulates 2 virtual cores in order to be able to process 2 threads. If the physical core is long-term on 100% load, will hardly have enough computing power left to emulate effectively 2 virtual cores which will result in poor multi-threading thus lower performance in some cases.

    Don't remember where I read this, but correct me if I am wrong.

    Btw, wonder what are the functions which are inaccessible on a Xeon + normal MB combo...
