I7 - whats mean + 120-150 eur or + 400 eur for hexa core cpu

Yes, I can think about AMD FX-8150 8 cores cpu ( it's cost like I5), but I don't know, amd at this time looks unreliable for me
Like I mentioned, I have been running an overclocked AMD Phenom II x4 955 and can real time any BR rip for any of the 1080i quality settings, but cannot do any of the 1080p settings. With that in mind, I've been recommending nothing short of an i5-2500k for anyone that wants to do on the fly 1080p. But curiosity got the best of me so I looked up some PassMark benchmarks. Knowing that there is nothing more important to video encoding than raw CPU speed here's how everything stacked up:

AMD Phenom II x4 965 3.4Ghz = 4201
Intel i5-2500k 3.3Ghz = 6582
AMD FX-8150 8-core 3.6Ghz = 8236

Checking prices at NewEgg, the FX-8150 is $30 less than the i5-2500k. Motherboards for AM3+ are also traditionally less expensive than an LGA 1155. I know where I'd spend my money. Stability of AMD as a company really is a non issue because by the time you'd need an upgrade for either CPU, you'd be looking at a next gen motherboard anyway.
