Which would perform better?

gpu is an important factor.
i5 3570k paired with asus z77 sabertooth will perform better as long as both rigs are paired with the same powerful gpu like a radeon 7850 or higher.

i have crossfire radeon hd 6870's

still, core i5. even better with overclock.
however, what is your current rig? are you just curious or want to upgrade? if you have an amd rig and have the opportunity to upgrade to an fx cpu, then the sole cpu upgrade will save you money. if you're upgrading whole rig from a phenom or core 2 quad, then core i5.

i have a fx-4100 with a cheap motherboard that i want to replace, mostly due to the fact i'm running crossfire at 16x 4x so switching to intel platform will be similer price

just as a heads up, the z77 sabertooth is aesthetics, there are mobos cheaper than it that probably are more effective.

Strictly speaking the Intels are faster but having like built many gaming rigs you won't really notice anything if all is higher end.

Been running a X6 1100T/8120 with Crosshair V with the new sapphire 7970 6Gb card in eyefinity and the performance is very high end, that said people prefer the comfort of having a Intel. At the end of the day its all your choice both setups are good.

PS: Z77x UD5h, hard pressed to find a better value orientated board, if you want something flashy then the Gigabyte Assassin board is probably the best Z77 out right now.

Stay away from ivy cpu's and this is why in details:

have you any idea how many came with the hot temps problems in ivy cpu's thread asking help?

And many more will come. I know i can help them, i can only bring them the bad news so you will never see 1 post from me in there. The problem is not oc related, trust me.

For gaming, the i5 3570k with an Asus Z77 Sabertooth, would give you a better performance, than the FX-8150 with a Crosshair V Formula.

sabertooth is just marketing hype . . .
ASRock Z77 Extreme4 $114.99
ASUS P8Z77-V $179.99
ASRock Z77 Extreme6 $174.99
ASUS P8Z77-V PRO $199.99

Bad experiences with Sabertooth boards, to much plastic and merely only cosmetic appeal. The above boards are all good performers, but again I will punt the Gigabyte Z77x UD5H.


If you are after Aesthetics and don't mind paying the requisite price tag then the Assassin is the best Z77 board without doubt, finally a Gigabyte high end board that delivers.
