Would a overclocked Intel I5-2500K struggle with 4k video?
Anyone^?
Yeah a 2500k will struggle.
As said above, you really need a big amount of virtual cores.
The 8320 has 8, the 4770k has 8 (they are better than the 8320's though) but the 2500k has 4.
If you're going intel get an i7 with HT, if not, get a 8320.
