Considering my budget, I have narrowed my choices to the followings:
- Intel Xeon X5660 2.80GHz 95w 6 cores ~ $1000 (new OEM on Ebay)
- Intel Xeon X5650 2.66GHz 95w 6 cores ~ $850 ( new OEM on Ebay)
- Intel Xeon E5649 2.53GHz 80W 6-Core ~ $780
- Intel Xeon E5645 2.40GHz 80W 6-Core ~ $560
- Intel Xeon W3680 3.33GHz 130W 6-Core ~ $600
X5650 and X5660 are more expensive but ES versions (engineering samples) can be found on Ebay for lower prices. I wonder how much risk is in buying ES? Your experience/opinion?
E5649 and E5645 are quite less expensive. What do I loose with them comparing to X line of Xeons? Do they over-clock better? II know they have lower QPI. Does it make a significant difference in their performance?
W3680 has a higher default clock speed at the price of higher TDP. It gives the impression of an already over-clocked Xeon. I imagine because of the high TDP, it has less over-clock capacity, right? Does it have a benefit?
Your inputs are appreciated.
