Xeon X5650 or X5680

post #1 of 23
Thread Starter 
Hello All,

I was just wondering if it is worth paying the extra 700 or so dollars for the the X5680. I haven't really followed Intel CPUs that closely. I am looking at running two of one of these CPU's with a EVGA Classified SR2 Mobo. I would greatly appreciate any input to help make my decision.

Depends on what you need it for, but most of the time its not. Most people dont need 24 virtual cores and 12 physical ones for normal stuff. Most businesses dont even need that much

IMO, get an i7 970, noctua d-14, evga classified mobo and Overclock the crap out of it

No. In fact, it's not worth paying for a single x5680.

What are you doing that would require 2 hex cores with HT? If you haven't been following intel's CPU offerings closely, you'd probably be better off saving your money and getting a single i7-980x. Unless you have a massive server farm, or are using it to run a lot of virtual machines or terminals simultaneously, there's absolutely no need for a dual-hex setup, at least not where bang-for-buck is concerned.

Well I am looking at doing the dual CPU as a way of avoiding having to upgrade for a long time since its going to be 2x 6 core CPUs with 24gb ram. I am also most likely going to be running several virtual machines, folding@home, a lot of gaming and so on. Either way I am going to be overclocking the crap out of whatever I get.

Does you really need more power than your 965 BE and 8GB of Corsair Dominators? Or are you like me, drooling over the SR-2 board even though I've no need for it. But I'm not going to kid myself, I'd buy that shat in a heart beat if I could afford an entire build based around it. We're all pc tech-enthusiasts,and jack off to benchmark numbers all day. So why not.

Still seems like overkill, but whatever. its not what the thread is about.

Its obviously not worth it though if youre overclocking...

The only reason would be if you couldn't get any more cores, but you needed more power and you werent overclocking.

Unless you're going to be running on some sort of phase cooling, I'd grab the X5650. It's the same story as the 920 vs. higher 900 series processors.

The X5650 has a maximum multiplier of 21x and the X5680 has a maximum multiplier of 26 (but really 25 is the highest usable).

As you can get to the speeds you will max out with on air/water with the 21x multi, I don't see much need for the X5680 for your uses.

I am in the same boat as you, i really want to do an SR-2 build and my thinking is that once i get that board i will not be upgrading my cpu/mobo for a long time. What you could do is get a single 6-core CPU and ram and just run the mobo with only 1 CPU until you save up and get another 6-core CPU. Right now 6 core would be best bang for the buck since the 8 cores are $3500 and when the new 10 cores come out those will be probably $5000+. As far as 24GB of ram thats way overkill but thats what i plan to put in my build as well. I hope you actually go through with this!

Edit: OP go check out the EVGA SR-2 Section on the EVGA Forum

Well I am actually basing most of my rig off of the Maximum PC Dream Machine 2010. I know what I am doing is major over kill but in the end I could save me from having to do many upgrades. Odds are I am going to get one CPU at a time, I was just wondering if there was really any point to the extra 700 for the CPUs. I will be doing Water cooling on it.
