Okay, first of all I apologize for asking this, as I've seen it a thousand times. However, I'm going to ask this question with a couple of twists that I couldn't find anywhere else.

My system has an i7-870 2.93 Ghz Quad Core, 16 gb ram, and a GTX 760. Recently, I purchased 3 entire used workstations for a grand total $88. Seriously. Each has Dual W5590 3.33 Ghz Quad Cores, 48 Gb ECC RAM, a bunch of drives, a RAID card, and a Quadro.

I see how a W5590 is quite similar to the i7-870 in age and specs. And while the 870 would win in a head-to-head competition, I'm not sure what will happen versus TWO Xeons, especially in games that are very, very CPU intensive. (For gaming, I'll transfer my GTX 760 and SSD C drive onto the server, so don't worry about those Quadros I won't use them.) What do you guys think?

Edit. P.S. This whole thing's just for pure curiosity's sake, since I've noticed my i7-870 showing its age in CPU-intensive games.

What a great buy!

Your I7-870 has a passmark rating of 5481 and a single thread rating of 1299.
By comparison, the W5590 has a passmark rating of 6310 and a single thread rating of 1470.
It would seem that even a single W5590 would be the superior gamer.

Most games that are cpu intensive are because of the demand on the single master core.
Activity on all threads is misleading, it is windows spreading the activity around to all available threads.
Few games can actually make use of more than 2-3 threads.

I think you can overclock your i7-870 and perhaps make up the difference in single thread performance.

FWIW, here are some numbers for a modern skylake cpu at stock:
i3-6100@3,7 5500total, 2102 single thread.
i3-6600K @3.5 7791 2166...

Oh but ark.intel.com says both have 4 cores 8 threads :O

You can expect a 25% boost of the :K: chips with overclocking.

The Xeon's spec sheet is completely blank on PCI revision stats, it doesn't even say 2.0 or how many lanes and stuff, what does that mean? Does it matter?

P.S. for anyone else reading this, here's the spreadsheet comparison vs the i7-870 and the Xeon W5590 (only 1 tho):

Oh wow that's interesting, however neither my mobo nor the Xeon mobo support overclocking. And for single core, it says they both turbo to 3.6 Ghz so I'm confused haha

Btw, I think they're FX3800's? Haha

Hmmm well if a Quadro FX3800 works on it (and I understand that this Quadro is PCI-e 2.0 IIRC) then my video card should work I guess?
 

well there not entirely terrible then.
bit old but still good enough for media output due to better colour reproduction.
