OC'd I5-750 @4GHz VS any other CPU?

[Clorky]

Hello, the title may be misleading, but my question is pretty simple:

I have I5-750 OC'd at @4GHz with Noctua NH-U9B SE2
Graphics card: 7950 OC'd either.

Could there be a bottleneck?
Which CPU would you recommend for a gamer? Will there be a huge FPS difference if i get for example I5-2550K and OC it to like 4,0GHz?
Which is the lowest price/highest quality CPU for gaming?
And last question - What is the temperature border for I5-750?

I think you'd see maybe 15% more fps max by taking that upgrade, more like 8-10% average. I wouldnt do it. I wish I could run my i5-750 that high, but all I have is some xigmatek cooler that costed $5 AR. I let the thing get as hot as 88C. wth right? If it blows I'll buy a 3570k.

Well if you get a 2500k/2550k then why stop at 4ghz? I'd think that 4.4-4.5ghz at similar vcore/temps would be more realistic and give a larger performance increase to you.

Yes.

3570k.

This is very game dependent. Some games love more cpu and others don't care. For the games that will use more cpu, you might see 10-30% fps gain and better minimums depending on your settings. Will it be HUGE? In my opinion, no.


Which is the lowest price/highest quality CPU for gaming?

Do you live near a Microcenter? This makes a difference.

And last question - What is the temperature border for I5-750?

I didn't like going higher than 75C, but I think thermal throttling begins around 95C? I'm not sure about that. It could be 105.

Thanks guys!

I can't. System resets after going higher than 4,1GHz - Overclock failed, but the cooler should be theoretically more effective, right?
Also, after Prime95 stresses for like an hour, max. temps in HWinfo reached 82 degrees Celsia, but only for like a second, so i don't really pay that much attention on that.

I don't really think it's worth swapping out a i5-750 clocked that high. Hang on to what you have until you have trouble getting a new game release to run satisfactorily.

This is with your i5-750?

4ghz is about the normal limit on the i5-750's without some hard core tweaking....Best I remember getting on mine is 4.4ghz or so but it takes a lot of tinkering around.

Just in case....You do realize you'd have to change your MB to upgrade.

The 2500/2550k's have a lot more overclocking headroom unless you get a dud of a chip. 4.4-4.5ghz or so shouldn't be too hard.

My 2550k's limit looks to be just above 5.6ghz with some crazy vcore

My 2550k does 4.5ghz @1.3v's VS my old i5-750 4ghz @1.325v's

Don't upgrade. I have a very similar system and you're only going to get a minimal increase in speed by exchanging your CPU+mboard. If you really need extra FPS then add another 7950 for CF.

I wouldn't bother until Haswell and DDR4. If you switch over now you're making a small upgrade to a platform that's nearing its EOL, and by the time it's necessary to make the large upgrade you have to start from scratch with a whole new socket.

Unless you're a 2560x1440 or 120hz gamer I see no reason why a 4ghz Nehalem isn't enough for any of today's games. And if that were the case you probably would've upgraded already without asking.

 

[Clorky]

Thank you.

Allright, so, last question - Is 4.0GHz temperatures allright reaching sometimes more than 75? Or should i go for 3,8GHz and keep the temperatures a little below 75?

Temps around 75*C under extreme loads isn't bad....Pretty much inline with the guys running stock intel coolers at stock speeds for the most part.

I would wait for haswell!

You can reduce any noticeable bottleneck by improving the memory i/o performance and keeping up to date when it comes to storage. Slow and aging drives make terrible bottlenecks for any games that are very sensitive to the page file.

 

[biostud]

If you don't have an SSD invest in one, that's a great upgrade.

 

[RaistlinZ]

That CPU should last you at least another year if you really want it to.

Hang in there, Haswell is right around the corner.. save your money now and buy the platform when it arrives. Basically what I'm doin.

 

[Denithor]

Let me give you the benefit of my personal experience here.

I went from an i5 750 @ 3.2GHz in my main box to an i7 3770 @ 4.2GHz. GPU is 7870 (not overclocked). I saw some improvements in games but nothing earthshattering, mostly things just got a little smoother.

Regarding temperatures, I run my gear in a very cramped HTPC case with the PSU mounted just above the HSF. With a stock cooler on the i5, when encoding video it routinely hit 95-98C and would throttle down to prevent overheating. I got a lower profile cooler (Scythe Kozuti) for the i7 and it never gets above 80C doing the same work. So your temps are fine, no worries there.

Overall I'd say wait for Haswell. I was planning to do exactly that but found my i7 in the for sale section here for $200 and couldn't resist.

I went from an i5-750 @ 4.1GHz to a 2500K @ 5.0GHz. In games the difference is minimal, usually unnoticeable (rendering however, it blows it away). At the time I was comparing Skyrim bottlenecks running more cells of the world at a time (before the game was patched and better optimized), as well as BF3 multiplayer. Basically any game/situation that was enough to deter my experience on the i5-750, the 2500K helped but wasn't dramatically better.

My i5 2500K overclocked to 4.5GHz doubled my benchmark scores from an E8400 using the same 2 GTX 460 1GB.

I'll never half to upgrade my CPU again.

I would put money 5 years from now you won't still be on a 2500k!

Heh, he just might be. My i7-930 feels just as fast today as the day I built it 2 years ago. I can certainly see it lasting 3 more years if my needs don't change. I bet the 2500k would be the same.
