Intel i5 2.63ghz 1156 to Intel i7 3.4ghz 1155 upgrade worth it ? or

Hi all

I have a i5 750 system running about 2.7ghz would a i7 sandybridge 3.4ghz be much faster i mean i know the mhz is higher but what about design would it blow my system away.

would windows 7 run better and be better at multitasking ?

2nd question would even the new sandybridge Intel Core i5-2500K 3.30GHz blow my i5 away to and would it be better at multitasking than the older i5

2rd and final question is there much difference between the i5 and i7 now ? as the older i5 and i7 systems where not much in it apart from the hyper threads.

cheers on any help you can give
 
if you can overclock your i5 there would not be that much difference, hardly worth it unless your doing something your current i5 can't handle.

The new 2nd Generation i-Series chips are faster yes. But the guy above is trying to say that if your current i5 can run everything fine then your not going to see a big improvement? Whereas if you do video encoding etc a new i7 2600k would be a lot faster than your current i5 due to the Extra clock speed and the HyperThreading. But at general Windows 7 usage there wouldn't be much/any difference. At the same clock speed the current i5 is 15% faster. so a 3Ghz SandyBridge i5 is roughly equal to a 3.45Ghz 1156 Socket i5. Also the new Chips run cooler, more efficiently and overclock better.

Basically, if your current PC is not slowing you down. Theres no NEED to upgrade.

Hope this helps.

EDIT: Spelling :P

Your cpu is fine and more than adequate. If you are wanting to upgrade for sake of it wait till autumn/end of this year for the new socket.


Sandybridge is good but its not worth forking out extra 300-400 pounds over the current system you have.

Id look at overclocking your i5 to 3.3/3.4 a nice mild overclock.

Op why are you running i5 750 at around stock speed?:confused: :rolleyes:

Most of them overclock to 3.8Ghz-4.0Ghz. Get that cpu overclocking as other posters mentioned and you wouldn't need to upgrade for a long time.

i5 750 at those overclocked speeds is a very powerful cpu:cool:

you mean ur getting a new system and want to know if i7 2600k is better than i5 750? ... yes, but it also depends on what u'll use the new sys for. if it's for gaming than i5 2500k is better. if its for heavily multithreaded apps then go with i7 2600k
 
yep its for my 2nd system.

the reason i am asking about the new i5 and i7 is becasue of price would you build the new sandybridge or would you just build another older i5 or i7 system becasue of cheaper price.

the sandybrisge is coming in at £1200 for the i7 and £1100 for the i5 version but i am sure you could knock off another £200 for an older i5 or i7 system.

the new i7 or i5 run at the same wattage now as the older i5s but are they even cooler now than the older i5 at the same wattage?
 
Don't do it. Not worth it.
Just overclock the 750. Most of them will do 4ghz without to much hassle.

Mine will do 4.4ghz with a significant vcore bump but I settled at 4ghz as it only needs 1.275v for that clock and temps are right on the money.
 
I agree with a lot of the posters here, the old LGA1156 i5 750 & 760 are fantastic CPUs with great overclocking potential when matched with other good components.

I have built 2 i5 750 PCs, my PC runs 4.0Ghz 24/7 (4.2Ghz-4.4Ghz when benchmarking)totally stable with no issues, the other PC (friends) runs 3.8Ghz 24/7 again totally stable.

If i was to build another PC, i would stick with the LGA1156 socket set, its slightly cheaper and IMO performs just as good (depending on your requirements for a PC)
 
To be honest, I'm curious as to the need for an i5 spec server. If you're just after a home file server and media centre, then I'd be most inclined to keep the i5 as your main PC, and get a low end AMD or Atom/ION for the job. Will be far cheaper than demoting your desktop with an i7!

I'm also curious about you asking if it will be "better at multitasking" - what are you running side by side that is taxing an i5? It takes some effort to use all 4 cores at once, I'm wondering whether you might be RAM limited rather than CPU bound...?

Of course if your server tasks really do need a number cruncher, ignore me, just checking you're not spending twice the money you need to :D

I think a lot of posters are failing to read exactly what you're saying.

It's like this. It's better to get a sandybridge system than an older Bloomfield/Lynnfield etc because they are noticeably faster and roughly the same price. However the question is, is it worthwhile for you to get an i7 2600k over an i7 2500k.

REmember that hte K series is there for overclocking. It also makes overclocking easy, and needs a P67 board (and not H67).

Beyond that only get an i7 2600k if you're using heavily multithreaded apps like video encoding (and even then, only if you use it regularly enough that you can't make do with a 2500K). Otherwise get an i5 2500k, and for things like gaming that i5 will not just beat the older i5s, it will even beat an older i7 980X.
http://www.anandtech.com/bench/Product/142?vs=288 (It wins in more gaming benches here than it loses)
It will also equal the 2600K in everything but the most heavily multithreaded apps.

Here's another example of the sandybridge i3 2100 matching an i7 940 in gaming performance:

cheers all for the help

lots to consider and you all have been most helpfull.

also herd if you are going SSD thats its best on a sandybridge system ?

is the sandybridge i7 cooler chipto run than my older 1156 i5 chip i have now as there both 95W wheres the older i7 was a 130W chip

cheers

Hi there,

So you will be putting the i5 750 system out to pasture and using a new system (possibly sandy bridge) as your new main system for "multi tasking"? May I ask what exactly you mean by multitasking? What applications are you mainly use and what do you reckon in the most intensive thing you do on your PC (even if you don't do it regularly)?

As for SSD, if your budget can support one then please get one. They make everyday life on a PC much more responsive and generally quicker. Sandy Bridge motherboards all have SATA 6G ports (some nahalem boards do, but not all) so with the current generation SSDs which can max out a SATAII/SATA 3G connection then these are certainly preferable.

The sandy bridge chips are pretty cool, even compared to the 95W s1156 chip (though please not that 95W i7 chips were released for s1156), so overclocking them and keeping them cool is a bit easier than the S1156 parts.
 
well i dont know if i should build a i7 for my main system and use my i5 as a server or keep my i5 as the main pc and build somthing that is less cost as a server but there does not seem to be much in price difference as i spend a lot on a case and psu which is nearly £250 just to start with.

you need a good psu and a case that can take at least 10 HD i am buying a sesonic psu as this is going to be a server, i already have a seasonic psu and a case that can do that on my i5 machine if i went the new i7 build way.
