So I decided to give away my g3258@ 4.6 to my younger brother.

I kinda gambled with cpu (see this thread http://forums.anandtech.com/showthread.php?t=2448907), it cost low 200 and mobo, got used z87 for $40 on ebay. I already had decent 4x2gb ddr3 ram, which im running 2300mhz now instead of 1400 (w very tight timings :p )on g3258. Total cost ~250.


How this cpu works is it is sort of like 4790s i7, but even lower volt/watts (65 vs 45w).

The max cpu multi would only go 33 on all 4 cores, but I bclk'd to 103, so I'm getting effectively 3400 with all cores 100%. Max turbo 1 core is now 4ghz. I'm cooling with same $20 fan I used on g3258 (i think CM T3), temps max out 70c on bench.

So here are some results comparing my 4.6 g3258@1.3 2c2t vs 1275L @ 4/3.4 4c8t

g3258 1275L
super pi1M 8.5s 9.3s
cpumark 4900 9700
cpuz single 1746 1475
cpuz multi 1686 4825
7zip NA ~21,000mips
cinebench15st 169 155
cb15 MT 335 699
firestrike+nv970 8242 9606
fstrike physics 4586 9617

So I guess the results are pretty close to xeon 1231v3/4770 nonk.
Multiplayer game so far that is noticeably smoother : rainbowsix beta, path of exile doesn't stutter in heavy mob areas. I haven't tested DA: inquisition yet, but it was unplayable on g3258,like 20fps, TW3 pretty choppy too, I will test those later but expecting improvement.

Edit: DA: inquisition apparently likes a lot of threads, went from 5-30fps choppy game to 60fps silky smooth with same gtx970

Update (could be relevant to anyone trying to OC non-K): I was messing around with bclk to try to get it to go higher. All cores 100% load are limited to 33x, with 103 bclk i made it 34x effectively..
I still wasn't happy, researached more, apparently mobo makers used to have MCE , that could make your cpu go max multi for all cores same as 1 core. This CPU being 3.9 single core max (33x all turbo as per intel spec), I tried to downgrade my mzi z87-g41 bios from 1.8, to 1.5, no luck.
Finally downgraded bios to 1.1 (unsupporeted for my cpu apparently xD) and boom, I got the enchanced turbo option.
Now benching and all cores run 3.9 :D .
Will test with some multi tweak to get it over 4.0 also.
