While doing research in this thread, I finally came across the cheap processors from LGA 1366, the 45nm Nehalem quad cores with hyperthreading. The top bin One of the better bins, X5570 with 2.93 Ghz base clock and 3.33 Ghz turbo starts at $21 shipped on ebay "Buy it now" listings.
Then I was surprised to see the stock speed Core i5 750 and Core i7 860 do well against both the Core i3 -4130 and FX-6350 in PC Lab's GTA V (CPU #2) benchmarks using both R9 290X OC and GTX 970 OC:

Core i3-4130= min 20 FPS, avg 24.9 FPS
Core i7 860= min 20 FPS, avg 24.4 FPS
Core i5 750= min 19 FPS, avg 23.2 FPS
FX 6350= min 18 FPS, avg 22.5 FPS
http://pclab.pl/art57777-22.html
Core i3-4130= min 29 FPS, avg 34.5 FPS
Core i7 860= min 28 FPS, avg 33.6 FPS
Core i5 750= min 27 FPS, avg 32 FPS
FX 6350= min 25 FPS, avg 30.1 FPS
According to Anandtech's review of the Core i7 860 here, the Bloomfield Nahelem processors were roughly in the same IPC ballpark as Lynnfield Nehalem processors in gaming tasks.
Comparing base clocks, Xeon X5570 has 133 Mhz advantage (2.93 Ghz vs. 2.80 GHz) compared to Core i7 860. On the turbo clock, the Core i7 860 has the 133 Mhz advanatage (3.46 Ghz vs. 333 Mhz).
So I'm thinking Xeon X5570 would be comparable to Core i7 860, but at about 1/3 the used market price. And much less than new processors from Intel (Core i3-4130) and AMD (FX 6350).
Of course, realize the I/O is going to be older on Nehalem based systems (compared to AM3+ with 970 chipset and LGA 1150). And idle will certainly be higher on LGA 1366 compared to a Haswell system. However, these are separate issues from gaming performance.
