J-jesus christ I woulda thought you'd have more common sense than to recommend an FX-8350 build.
The i7 is better in every way except in cost. It's faster, more efficient and wins in virtually every every test.
The architectures are different. Intel processors are stronger in single threaded applications which pretty much dominate the gaming area. As previously said, there are very few games that actually use more than 4 cores and even then, there's negligible difference between an i5 and the 8350.
AMD processors are strong in Multi-threaded applications or core intense applications. Many people buy an 8 core CPU for video editing which do better compared to an i5 but not an i7.
There's also no upgrade path or new generation CPUs from AMD AM3+ line.
There are two ways to shut the fanboy up, ask him to post credible sources of gaming benchmarks. Youtube videos are not credible sources. They are garbage and never tell the whole story. AnandTech, Tom's, Guru, HardOCP, TechSpot.
Let me elaborate more if I didn't come across clear.
i7 4790k is built on a 22nm manufacturing process while the 8350 is built on a 32nm process, the i7 manufacturing is so much newer giving you a more powerful, yet cooler processor, and no more GHz doesn't mean its a better CPU...... Also, it has a 2.2x lower power consumption. Next, it has 2x more l3 cache per core, meaning since the i7 has four cores, it has the same l3 cache. Shit, it even got a 2x better score on the C4D benchmark which is ALL cpu. Need I go further why the FX-8350 is a poor choice?
