Summary: My motherboard came with an i3 and i was able to upgrade to the i7. In my opinion the i7 860 is one of the best CPU's for a motherboard that has a 1156 CPU socket. You can save money buying a used CPU however, the only thing that you don't know is if the CPU sustained high amounts of heat. I recommend buying used CPU's. Great product!
Summary: I used to have an Intel Core i5 661 3.33 Ghz 4Mb cache and it was slow with games and image manipulation softwares. Now with this cpu my computer is much more faster and has a great performance. It's a huge difference.
Summary: After a horrible experience ordering an i7-860 through eBay and having an i7-860s arrive, a seller that threatened to pack his tent in the night and leave me stranded, and having to go PayPal Claim "up in that" to get my money back, this was a great experience. It was not the low-powered (slower) one that I had specifically chosen to avoid. It was as-described, on time, and the seller was pleasant to work with. Day and Night difference between the two experiences.
