The TR 1950X is going for $449.99 on Newegg through Saturday:
25% off its most recent price of $599, and half the price of the 2950X!
This is presumably a fire sale of the last of their first-gen stock, so if you were waiting for a deal on a new 1950X this might be one of the last ones.
Edit: looks like the deal might be over already. The page is now displaying third-party marketplace sellers (at ~$599) instead of Newegg.
