Should i upgrade 3930k to 4930k? - Page 3

post #21 of 23
So I just picked this baby up!



Will be installing tomorrow hopefully and should have my brand new 3960X back from RMA next week which I will be putting up in the marketplace, if anybody is interested. Thanks guys!

You make good points. I'm just concerned that I'll pull the trigger on a 4930K and wind up right back at 4.5ghz (which is precisely where my 3820 is now), and yes I know it has slightly higher performance per clock, but not enough to warrant a $600 upgrade.

Also, from what I gather, SB-e is generally thermally limited, while IB-e is voltage limited. I'm going to be doing a full custom watercooling build along with this upgrade, so temps won't be a problem. I feel like I would probably have a better shot at a high clock on a SB-e which would benefit more from custom wc than IB-e, which will be limited by voltage long before temperature becomes an issue. The overclock is the thing for me, so while there may not be much real world difference between 4.5 vs 4.7, it's a $2000 difference (watercooling included!)to me - the thrill is in those extra 200mhz. So, the moral of the story is SEND ME YOUR CHIP! lol

But you're right, I have equal chances of getting a good or bad chip either way I go, so I guess it just comes down to which way I feel luckier.

With a decent water cooled setup, it's pretty likely that you'd be able to hit 5GHz+ with a 3930K.

I can get 4.9GHz using a halfway decent air cooler, only temps are too high to use it with that cooler.

It's a tough call, but at this point (unfortunately) I'd probably recommend the 3930K over the 4930K to overclockers.

I was hoping for more from the 4930K and potentially upgrading to it myself, but I seem to have trouble finding any reason for me to now.

Actually, in the weeks since that earlier post, I went with a 4930K which I have comfortably clocked to 4.6ghz. Preliminary totally unscientific comparison seems to indicate that at 4.6ghz it achieves benchmark results on par with a 3930K at 4.8-4.9, so I'm reasonably happy with it. I can't get it to 4.7ghz without pushing vcore into the 1.45v area, which is too high for 24/7 oc, but with better cooling (which I am considering) I should be able to benchmark with it at 4.7ghz, which should be roughly equivalent to a 3930k at 5ghz.

The moral of the story is: if you already have a solid performing 3930k, there's no reason whatsoever to upgrade. If you have a crappy SB-e, it probably is worth the upgrade. While I was really nervous I'd get a really low performer, I'm pretty happy with how it turned out. smile.gif
