Sandy Bridge or Ivy Bridge [new build question] [need help]

[ttechf]

I run 4.5ghz on my Ivy and my chip gets up to around 95-98c running LinX. However in real-world usage patterns it rarely gets above the 70's. Plus, Ivy seems perfectly happy to run at 90c+ all day, and it's not dumping a bunch of heat into your room even so.

Hmm, good to know. Thank you. : )

The main question is whether or not you want to to sacrifice cpu speed for gpu speed?

If you go with SB you have lower temps, but not as much gpu power. If you go with IB you have slightly higher temps, but more gpu power.

If you keep IB stock or not overclocked much, you will have lower temps. IB isn't to hot for a htpc, you just can't push it has.

So if you want gpu power and average temps go IB. If you want lower temps, go SB.

Thank you, I will bear this in mind. : )

I don't get it. I would think that for an HTPC, which by definition is not going to be OCed, that an Ivy 3570 would be perfect. Buy it and don't look back.

Yeah I just dont want any regrets with whatever processor I end up going with or any thoughts like " I should of gone with ________ processor" lol.

Understand the sentiment, but you can always come up with that statement no matter what piece of hardware you purchase. There will always be another piece you could have bought for only $XX more or $XX less and given you better/similar/better bang-for-buck performance, at least on some people's charts........

Best you can do is buy what you think is best for your purposes and then quit overthinking/rethinking the buy afterward.

I think there are quite a few who thinks that way, bought the best processor they could afford, in which case is a Core i7 2600K/Core i7 3770K and only to regret it a few months down the road. This is a true story and it isn't made up. Unless you're certain that the program you're running benefits from having 4 extra threads which would save you time, 1 hour or more, the upper end Core i7 is pretty much a luxury.

With the money saved from going for the middle range Core i5, you could've spent it on a bigger or more SSDs in RAID. The performance increase there is way more obvious to the average user. That being said, I do have a Core i5 3570K and if I were to spend more money on it, it'll be the Core i7 3930K, not a Core i7 3770K.

Well I won't have any regrets buying an i5 or i7, I just dont know which one, lol. I know both of them are wicked fast and more than enough power than I need and power I'll never use. It's just future proofing myself. I figure if I buy an i7 instead of an i5, it gives me a couple extra years due to it's hyper threading. Thats just what I think, maybe I'm wrong. lol.

You could buy it anyway if you think you actually needwant it, your money to spend anyway at the end of the day. 😉

What voltage? My 3570k runs into the low 80s at 4.5ghz and around 1.25v.

4.6 needs over 1.3v and runs to around 90 in Intel burn test.

After fooling around with LLC on/off, I've found I'm stable at 4.5ghz with an offset of +92mv, which results in a full load voltage of 1.248v as reported by CPU-Z. I run -25mv in bios and +117 from Intel's Extreme Tuning Utility so I have lower voltages at partial loads.

With my new lower load voltage, Prime95 loads me at 78-80c depending on ambient, while LinX takes me up to approximately 90c. I was running a higher voltage before and experiencing higher temps.

Also if you like cube cases, Check out this AMAZING build using the mini-itx. It fits together so well it's shocking. packing so much power in such a small box.

"The only solution that we could think of was to use a Dremel tool and cut out the chassis for the lines to properly fit. We used the ATI themed Dremel tool with some sanding bands to cut some nice circular holes in the aluminum frame."

Yeah, that fits together amazingly well.
