Pretty decent deal for a S2066 CPU from Amazon.
** Socket LGA 2066
** Compatibale with Intel® X299 Chipset
** 6 Cores/12 Threads
** Max Number of PCI Express Lanes 28
Intel provides International warranty so should any issues arise you should RMA directly through them. My last Intel CPU RMA (~4 weeks ago) was completed in a 7 day turnaround (with Intel covering all costs).
6 left in stock (more on the way), so you can backorder for the same price once the current 6 sell out.
Cheapest local store stock is MSY @ $509, so a saving of ~$90.
140w tdp and $399 for the cheapest motherboard at PCCG.
Better off going intel 8th gen i7.
