yeah, i've been eyeballing one for when my truck sells; I too have never had state of the art, but have always ended up with 2 generations old top of the line..... This little i3 ive been on since I received it can only do so much =)
It's hard to justify spending 2K on a motherboard and processor, but I figure I would not need to replace them for at least 6+ years..... that makes it worth it to me.
80mb cache.... that's really where it hits the home run. Most people can't imagine the difference between a 2Mb cache and a 10Mb cache intel chip; until they actually experience it..... it's a night and day difference.
My downside is I would be footing for a MB, CPU and a cooler; which I definitely will not be doing air since AIO's are so efficient and easy on the wallet these days.
If I did get it; Ill definitely be putting it towards cryptonight in its spare time. It would be a waste to not.
My 1920 has done well. I run 4 Vega 56 and the 1920 it will actually roi. Which is impressive.
