Worth the extra money for Sandy Bridge?

post #1 of 23
Thread Starter 
Alright, so I'm thinking that I want to upgrade my CPU/Mobo/RAM. As far as Intel's concerned, I have two options:
  1. Core i5-760. I could either get the parts used which would be a lot cheaper than Sandy Bridge, or get them new which would be a little bit cheaper than Sandy Bridge.
  2. Core i5-2300. I'll pretty much have to buy new at this point in time, and the i5-2300 is around the same price as the 760 where I live, motherboards are a bit more expensive.

So, do you think it would be worth the extra money for a 2300? If I got a 760 I would overclock it, but that would basically not be happening with a 2300, so it would have to stay at 2.8, 3.1 turbo.

It has a lower turbo frequency and 2MB less cache as well.

If you had the choice between i5-760 + P55 and i5-2300 + P67, what would you choose?

Cheers

No, the 760 will outperform the 2300 because of the sole reason that it can OC.

With a P67 motherboard you could still overclock the i5 2300 to 3.2GHz with turbo and it will get as high as 3.5GHz when it's a single threaded app. Besides the i5 at stock speeds is already good. I just don't get why you don't just go for the 2500K, it's usually not that much more expensive while you get a pretty big boost.

i5 2300 would be my choice.

I would have to go with the 760 in this case, however you should really just spend the extra few bucks and get the 2500k

760 over the 2300, but I would spend a few more bucks and get the 2500k so you can overclock it.

If you are going SB route DEFO get a K series CPU as they actually OC, and try and make sure that its D1 stepping as D2 only oc to about 4.2ghz where as D1 does 5.2ghz. BUT the SB chips have a cold bug, it has been proven that the cpu should be atleast 20c before it boots. So no extreme watercooling or anything beyond that.

Thanks for the replies

The reason I haven't really considered the 2500K is that a new 2300 would already be at the top end of my budget, and the 2500K would mean spending more money than I'll have

So I think the general consensus is that it's not particularly worth going with Sandy Bridge unless I get an unlocked CPU?

I'd only be on air anyway, most likely by the time I have the money/confidence/need to get into extreme cooling, I won't have the i5 anymore.

EDIT: Is the cache difference not really worth worrying about?

I thought it was the d2 stepping that we wanted not the d1???
aren't all retail chips d2 anyways?

I'd save up your money before getting either one then. A stock Sandy Bridge i5 already outperforms the Lynnfield by quite a bit

1156 is dead already.

Alright, I think I'll probably save up for a bit and grab a 2500K. By the time I have some cash people might know more about which boards are best, etc. anyway.

Should be my last two questions:

Is the loss of cache no biggie?
I know that you can only modify the turbo multiplier, not the base one. Do you know if there are any problems with this, like the chip not going into turbo mode when it should or something? Or does it work well and always go to the overclocked frequency when you need it to?

Thanks guys, I'll be dishing out rep now
