Question Confused regarding Xeon W3680 Upgrade

Scored an HP Z400 on Ebay for only $100. Works like a champ. Has Xeon W3680. It does run all my games with acceptable speeds (to me) but I was curious if there's any upgrade path at all.

looked up HP Z400 spec sheet and here's what they say:

  • Intel Xeon W3503, 2.40 GHz, 4 MB cache, 1066 memory, 4.8GT/s QPI, Dual-Core
  • Intel Xeon W3505, 2.53 GHz, 4 MB cache, 1066 memory, 4.8GT/s QPI, Dual-Core
  • Intel Xeon W3520, 2.66 GHz, 8 MB cache, 1066 memory, 4.8GT/s QPI, Quad-Core, HT, Turbo
  • Intel Xeon W3540, 2.93 GHz, 8 MB cache, 1066 memory, 4.8GT/s QPI, Quad-Core, HT, Turbo
  • Intel Xeon W3570, 3.20 GHz, 8 MB cache, 1333 memory, 6.4GT/s, Quad-Core, HT, Turbo

Do you see a Xeon W3680 anywhere here? What gives? Is there more than one HP Z400 variation out there? Did the ebay dude somehow "hack" a W3680 in there? Highly unlikely since there lots of guys on youtube with this same exact CPU and PC combo. So what am I missing?

If I can upgrade, what can I upgrade to?

Just how fast is a W3680?


User bench says it's as fast as a i5-4690, but that's probably BS. Which mainstream CPU has similar performance overall?

Thanks

Edit: If this has any relevancy at all I got 772 Cb in Cinebench R15 (@stock off course)

Not much more you can do as far as CPU wiht that HP, though you might be able to run a Xeon X5690. Not sure. I asssume that board won't OC either.

The CPUs you listed are all Bloomfiled (Nehalem architecture) CPUs, yours is a Gulftown (Westmere architecture) CPU. Both architectures are basically identical apart from the node shrink and the higher possible core count on Westmere.
Here are the specs of your CPU:
Xeon W3680
  • SLBV2 (B1)
3.33 GHz1/1/1/1/2/266 × 256 KiB12 MiB1 × 6.4 GT/s QPI25×3 × DDR3-13330.8–1.375 V130 WLGA 1366
On that socket this is almost the fastest CPU you can get, an upgrade wouldn't make much sense.
