First the 3 year AMD Warranty on that processor is now voided. AMD voids the Warranty on any broken or bent processor pins (Customer Error).
Second the only way to see if you have a very expensive paperweight or not is by installing the Processor and see if it boots up and runs normally under heavy loads or stress.
Many pins are redundant like the Ground pins on the processor. You might be able to get by with a ground pin being broken without issue but with two pins depends on what their functions were with the processor. Only way is by installing the processor and see if it works correctly.
You might be able to get it repaired if you find a place that does that type of repairs. It takes special equipment and supplies to replace a broken processor pin and it probably won't be cheap but rather expensive.
Google the internet and see if there are any repair centers that repairs broken pins on a processor and how much it will cost if the processor doesn't work correctly or doesn't boot up when you installed it.
EDIT: I really feel for you. What happened to you is something that can happen to any User. If the processor is a expensive Paperweight then just chalk it up one bad learning experience that you won't ever do again in the future.
