Hello all. I am looking to upgrade, and have settled on getting either the Core i7 5820k or 6700k. I will be using my build for gaming, video editing, streaming, and multitasking. I was wondering if I should go with the 5820k because of the two extra cores, or if i would benefit more from the 6700k's higher clock speed. I will also be using SLI in the future, so I think the extra PCIE lanes of the 5820k would be a nice bonus. Thank you for your help

the 6700k won't make a huge difference in games even.

The higher clock speed of the 6700 is more important for gaming than more cores. For rendering more cores are better but the hyperthreading on a 6700k should still do pretty well.

The 6700k will also have enough PCIe lanes for 2 way SLI. You don't need to worry about that unless you are considering 3 or 4 GPUs.
 


I don't think it's a dumb question or a troll. The 4.0GHz 6700k should do better for gaming than the 3.3GHz 5820k. The 5820k would do better for all his other tasks but it's also more expensive.
 

The CPUs alone might be in a similar price range but once you add the LGA2011 motherboard, quad DDR4 kit, LGA2011 HSF (needs to handle 30-50W extra TDP) and possibly other extras to make the LGA2011 CPUs perform well, you end up with something considerably more expensive than an i7 with a mainstream OC motherboard, assuming OP actually cares about OC as an option.

Each CPU has its uses, even if it seems silly that the i7-6700k might end up more expensive than the i7-5820k in some markets. Having 50% more 30% slower cores don't do you much good in most games.

can you get any closer than that? ;-)

yes, the i7 6700k is horrible value. if it was cheaper, fine. but for multithreaded apps, +2 cores +4 threads is going to make a huge difference
