I'm sorry to read that you didn't hear about the 2nd generation processors until after you made your purchase. The first generation is still a great value and is still on Intel's processor price list.
Unfortunately, the first generation processors have a different chipset than the 2nd generation so you can't upgrade.
- Intel® Core™ i7-2600S Processor uses the Intel Series 6 Express chipset
- Intel® Core™ i7-980 Processor uses the Intel Series 5 Express chipset
