whoa missed that part. Well if his company is that serious, yes by all means go SR2 with quad 580.

Yeah, it is obviously the better setup and he has the money. Been saying this the whole time. Plus the new havok can use 12 cores, I'd want the 12 cores.

make sure to get 580 3gbs if this is a free system, they'l allow you to run SUPER HI-RES surround setups

Well, I am SO glad I found this thread.

I am in a similar situation, except that what if 2 Xeon E5649's and 48 GB ECC was free?

I've been mulling this over for a while. For around the same price, I could build a sandybridge, or the dual Xeon rig. I don't need 2 high end machines.

I'm currently running an i7 930 (gasp, gasp and probably cursing me) not overclocked with a 580.

I'm pretty sure one of those Xeon's overclocked would beat an i7 930, and they are 6 core.

I have a big-*^& IBM server with dual 6 core Xeon's I am playing with (put Win 7 x64) but I can't fit a dual width video card, so I don't have a way to compare it with a different box for gaming. Oh, it will fold all day long.

The other thing is that the server usually use far more electricity than a desktop, I don't know but I found no where in the server settings in BIOS for power options, I believe it runs full out all the time.

So, if the 2 Xeon's and 48 gig of ram was given to you, would you build the Xeon or a SandyBridge?

How the hell are you getting a rig like that for free!?

The BIG IBM server I am testing on is not mine. It is going to be an ESXi server after I get done playing with it.

Only 2 CPU's (E5649's) and 6 sticks of 8 Gig ECC Registered memory are free. They were 'extra' parts left over for a different project at work.

So, for a dual Xeon 48G setup, I will have to spend around:

$425-$600 for the motherboard
$200 or so for a power supply
$300 or so for a case if I can't use one I already have
$100 for two heatsinks/fans

OR for a SandyBridge

$250 to $350 for an ASUS motherboard
$250 to $320 for an I5 or I7 2600k
$250 for 24G of ram
$150 for power supply

$1025 to $1200 versus $900 to $1070

For me, they are close enough that either one would not make or break my budget.

I'm just wondering about the performance difference and if the power consumption would be significant.

Any pointers to where some tests have been done on the dual Xeon setup? I can find plenty of information on the SandyBridge.

Or, maybe I can trade the Xeon's and memory for a Sandybridge setup?

oh, and I bumped up my i7 to 3.4GHz, so I am officially overclocked! I went for a conservative overclock and it was SO easy I was impressed.

Well if you went sandy you could sell your 2 cpus and your 6 sticks of ram for more than the sb build would cost.

Yes, IF I went SB. That is what I am trying to figure out.

I will admit that having a 'unique' machine has me interested, say an EVGA SR-2 with a very mild overclock.

I have a 'gut' feeling that a SB, properly overclocked to it's potential, would actually out perform a dual 6 core Xeon setup for most normal use, such as games and the ocassional video rendering/transcoding I do, neither of which is really highly multi-threaded anyway. (well, I sometimes use Xilisofts ripper/decoder/transcoder, which WILL use all 6/12 cores from one Xeon, I have tried it)

But, you have a point. I could build the dual Xeon rig (I kind of want to anyway, just to say I did) and run some benchmarks on it, have a friend of mine run the same benchmarks on his overclocked SB, and compare the results.

If mine is comparable, I can keep it. If his is a lot better, I could sell my setup for a SB setup.

All world records for most stuff is on a Dual Xeon.

The best concrete numbers I have found were for SPEC Cint2006 results.
A server with what will be my exact (non overclocked) system gets a 37 rating , while a SB 3.4Ghz/Turbo boost to 3.8 has 45

Again, this is just integer performance, but if the E5649 would overclock to 3.2GHz it should be around 47. Of course if the SB was overclocked to 4.5Ghz, IT would go up to around 53. I'm pretty sure that 2 of the top dog Xeon's, overclocked, would outperform a SB by a big margin, but I'm 'stuck' with these mid-line Xeons.

Other than loose what little brain power I have left going over numbers and options, I think I will just build the Xeon, overclock it to where I can, run some tests and have a friend run the same tests on his.

If anyone is interested, I will do a blog or post results once I get everything together. I am ordering an EVGA SR-2 even as I am typing this.....
