Funny.
And did he foolishly build an X58 chipset-based Intel computer? If he did, then yes, you're correct. However in folding applications and video rendering his would probably blow your computer sky-high.
Anyone who builds a computer with an i5-2500K for instance, is using some of the latest hardware, which AMD is far behind on. I'm guessing you built some Phenom II computer, let me guess, a 1090T or 1100T? You see the thing is, an i5-2500K CPU can easily be overclocked up to 4.5GHz, note: easily. I've not heard of too many people doing that with Phenom II's.... you have to have some insane cooling solution and be very careful as the auto-shutdown on those CPUs is much lower than Intel's. Phenom II is ~2 year old hardware, i5-2500K and its siblings are less than a year old and blow anything of AMD's out of the water right now. Yes your friend may have foolishly bought something from Intel that is also old technology, but I assure you, any of us here with 2500K/2600K CPUs, know how little we actually spent and how much extra we got free. My CPU is at 4.5GHz and I know some who have their own even higher... it doesn't cost extra money to OC, so while you're probably at a slow stock speed, we'll be blasting by you. Enjoy your 2 year old technology buddy, and sorry you are so stubborn.
And before you say I'm an Intel-fanboy, I'm really not, I'd like to see AMD take back some of the market, if they ever get caught up... Bulldozer should have been out around the time Sandybridge came out, if AMD can't catch up soon, Intel will have no reason to keep prices cheap.
And you say you did 2 months worth of research? When? How? What kind of research? Let me put AMD's best Phenom II up against the i5-2500K, which is not Intel's top Sandybridge CPU, the i7-2600K is, as it has Hyper-threading, but the 2500K has been shown to be a bit better in gaming at times.
Here you are, the 6 core beast from AMD, the Phenom II x6 1100T BE vs the 4 core Intel i5-2500K.... let's see what the benchmarks show...
