So true...some facts about xeons (my experiences):
fact1-I had an E8400 (Q743A) that would run 4.3GHz with 1.344vcore. P95 stable for 9+ hours and passed all 3D benchies.
fact2- I had an E3110 (Q746A534) that wouldn't run 4.3GHz stable no matter how much vcore you put to it and I tried up to 1.6vcore.
fact3- I currently have another E3110 (same batch as the first one-Q746A534) that requires 1.456vcore to be 4.3GHz P95 stable.
So far, any mention of the Xeons being better as far as lower vcore required is untrue. Do they last longer? Dunno as I ran mine for a couple of years and sold them. Do they run hotter/cooler? Nope. In my water loop all of these recent CPUs have topped out at the same temps (+/- 2degC) when running P95 for 9+ hours. There is a lot of conjecture on all forums as to what makes the xeon different than the standard intel desktop chips. I have used xeons for my gaming and desktop rigs for years. Frankly I can't say that any xeon OCs better than its desktop counterpart. I had Xeon3060s with batch codes L629B and L631B that did not perform any differently than desktop cpus with the same batch codes. All would do 3.71GHz with 1.41vcore. Under phase/dice/ln2 that may be a different story but under good air or water it is the same.
Right now it doesn't matter which one you buy. It does matter what batch/FPO# CPU you buy. That has always been true. And if you are lucky enough to find a Q743A I suggest buying it.
