The Pentium G3258 isn't yet available; it's expected in stock towards the end of June. However, pre-order pricing puts it about £10 lower than AMD's Athlon X4 750K. That's impressive of course, but it doesn't take into account the fact that overclocking Intel's K-series (and now 20th anniversary Pentium) processors require a higher-end platform.

Intel says its Pentium G3258 is compatible with 8- and 9-series chipsets, and we used MSI's Z97 Gaming 7 for our tests. Of course, you don't need a £130 board. Z97-based offerings start at around £70.

But AMD's Athlon X4 750K is more flexible in that regard. The MSI FM2-A85X-G65 we're using is no longer available. A rough equivalent, MSI's A88X-G45, goes for £90, though. And you can find plenty-capable A88X-based motherboards for under £50. Take that difference into consideration when you talk about platform pricing.

    Been waiting reviews for a 'sister' build. Thanks.

    this beat every amd up to amd 8350, and still you need to oc the 8350 to get better fps in some games. this pretty much leaves amd dead in the water in gaming cpu's

    This is a very good CPU for the price, AMD should be worried, and in fact everyone should. This CPU is pretty much removing for AMD one of their last areas in which AMD did well- cheap overclockable CPUs. AMD need to respond to this, perhaps make a GPU disabled kaveri chip that overclocks better than the 7850k does? If AMD don't respond then we lose the last competitor to intel, and everyone knows what that would mean for the market.

    correct me if i am wrong but overclocking this processor requires z motherboard, and a pontent cooler. These two combined will add up to more than the difference with the i3. What you end up is hot, overclocked processor that is inferior in almost all benchmarks for no less money. The only logic I can see is to buy this now and after a couple of years upgrade to i7 and overclock it also.

    stock cooler should not be used anyways, so your wrong ivyanev.
    dont buy a pc so cheap you cant cool it or have a good motherboard.

    Minimum of £80 for a low end Z97 motherboard + £55 for the unlocked Pentium with an overclock that is not guaranteed.

    When the i3 is £90 and can be put in a cheap (£40) H81 motherboard without needing the effort of finding a stable overclock it seems a bit risky to go for the Pentium.

    However, if a later upgrade to an i5K or i7K is planned (or you need the Z series chipset features) then the Pentium is a good way to start saving towards that upgrade while not compromising on the expense of an i3 or drop in performance of a regular Pentium.

    You dont need an Z series to OC this monster.You need just an "solid" Asus h81/b85/h97 mobo(with al least one heatshrink on the VRM).Asus announced that they will unlock overclocking on their h81/b85/h97 mobos.Plus you don't need a serious cooler,
    Zalman CNPS10X Performa(~35$) or
    Thermalright True Spirit 120i(~45$) should be enough to keep it under 80 degrees.

    Is there a slight anomaly in the Tomb Raider graphs? The OC G3258 appears a lot slower than the normal one...

    Well, I have my G3258 running at 4.3Ghz at 1.33v on a £30 MSI H81 mobo, coupled with a £15 Freezer 7 pro heatsink/fan. That's only £85 in total for quite a fair amount of performance.

    Anything above 4.3Ghz wasn't stable, even with the voltage up to 1.34v (not prepared to try higher than that as temps were too high). This was likely down to the cheap mobo, but I'm not going to complain about that, as it's still a nice overclock for the money.
