Haswell vs Ivy Bridge Best Option?

[Twist86]

So I'm torn between these two chips, on one hand Haswell = newer but it runs like molten lava, sucks up more power, and only gives a 10% increase over Ivy Bridge (I also hear Broadleaf has different chipset voltages which will make Haswell boards obsolete anyways for "future proofing") . The other half is Ivy bridge is an older socket but runs cooler and uses less power at the same price point. My goal is to overclock either chip to 4.0ghz for now...and more later down the road as I need it.


My "builds" between the two are

Total Price = 446.94 + $30 MIR. I can knock an extra $5 buying the CPU on amazon. Can buy them for $200 used on Ebay (not sure if risk is worth it)

Total Price = $432.74 + $10 MIR. I think I might need to buy a better cooling solution however (like the $74 Noctura options) as I read people with REAL water setups are having horrible temps.



I'm just torn....I wont be upgrading for a long time as my Q6600 lasted me 7 years lol. Thank you for any wisdom you can provide me.

Alright after looking at choices I decided to stick with haswell....it ends up being cheaper/better in the long run. Thanks for the help man.
