Microcenter has the AMD Ryzen Threadripper 1950x on sale for 629.99. In store pickup only. Save $30 when bundled with specific motherboards.
Threadripper 2 will be announced this fall, so it’s expected to see price drops like this. Fantastic deal, but consider that Threadripper 2 will have a high end of 32 core / 64 threads.
