Gallatin L3 didn't help at all for gaming or cache dependent tasks, it was slow cache and unable to be used in the same manner that L2 cache is. Gallatin was roughly 10-20% faster than Northwood due to the L3 cache and had it been fast L2 that performance increase would have been larger.
CM stopped at 3.6 because Core2 had been released so Intel dropped all Pentium4 lines, its capable of hitting 4.3 Ghz on Air/AIO with little issue ..Presshot would have extreme stability issues past 4Ghz due to heat without exotic cooling of some form. There are records of the 661 hitting 4.5Ghz stable on HWbot, there are also crazy people who have a Presshot EE at 4.4Ghz they also needed a nuclear reactor to power it and HVAC for the room it was running in. (Likey used some exotic cooling like LN2 or chiller for it)
Pressler and Smithfield are two dies glued together, Intel never produced multicore Pentium4 CPUs. Multicore didn't happen till Core2 CPUs.
All Smithfield processors were made of two 90 nm Prescott cores, next to each other on a single die with 1 MB of Level 2 (L2) cache per core.
Presler introduced the 'multi-chip module, or MCM, which consisted of two single-core dies placed next to each other on the same substrate package.
There was this slight difference, just mentioning it since I saw it on Wiki, doesn't matter in the grand scheme of things anyway.
Extreme Editions had more tech things going for them (XE versions of Smith/Press).
So in some order I got from this:
1. Pentium D 965 in "single core mode" = 65mm Presscot-2m (a cooler Press-2m at 3.73Ghz), ability to run "dual core mode" for WinXP (but hot)
2. CedarMill 661 (smartest choice due to lower thermals/TDP + higher OC potential)
3. 2m 3.73 EE Presshot (burn baby burn, but faster than CM661 at stock)
Then it all boils down to availability, price, and mobo CPU support (965 works with like 1 or maybe 2 Intel only chipsets).
Availability of any of these will be limited but of the three the 661 will be easiest to get and cheapest, the EE editions can be very expensive with the Fire starter 2m being exceptionally painful to buy.
The 965 should work in any late 775 Pentium4 motherboard that has a VRM that can handle its power draw.
