I have acquired two Intel 5620 CPUs, just wanted some opinions on whether it was worth using one/both of them for a home build (or not!).
My home PC is an ageing Intel Gallatin EE 3.4GHz running Windows XP which is hardly used, in fact I tend to use a laptop with an Intel 7300 2Hgz C2D for gaming (mostly Sega's Football Manager series) because it's a lot quicker than the PC. I would assume that a single 5620 is going to be a much quicker CPU than either of these.
It would be used for ripping CDs in to FLAC, encoding films so that I can access a library of movies from my AV amp, and playing Football Manager and some other games.
It looks like if I wanted to do any overclocking (which apparently the Xeon E5620 is typcially quite capable of) if I used both of these CPUs then I'm limited to the almost £500 EVGA SR-2 board (which I don't think would fit in to my beautiful Antec P182-SE case anyway) as I don't think any of the £200-£300 workstation boards allow these Xeons to be ramped up.
On the other hand, I think that there are a few good X58 boards that support a single Xeon.
two cpu's might perform better in some applications . however they cost too much because you need more ram and most applications don't utilise all the cores . a single e5620 overclocked performs like a i7 980x.
I think I'll go down the route of getting a Westmare-compatible X58 board and hopefully getting 3.8-4.0GHz out of it, rather than a workstation board that only gives me 2x stock 2.4Ghz 5620s, since the SR-2 isn't really a viable option (I don't think, anyway!).
Come to think of it, as well as wanting to re-use my existing P182-SE case, I think the SR-2 only has PCIx slots so my PCI DAB radio card wouldn't have fitted in it which was another thing I was hoping to be able to re-use.
