yeah, I finally decided I had to buy because my pc is so close to falling apart. If you mentioned that because of me mentioning 4700x above, though, that was a typo. 3700x*.At which point do we actually commit to buying anything given the rate of development of CPU's recently. That is to say, by the time 4700x hits the shelves, a newer X-chip will be just on the horizon.
I'm only upgrading because my I3 - 6100 and gtx980 is starting to show it's age. Whether it's a 3600, 3700 or 3900, it will still be an effective upgrade.
Btw, someone I talk to who has a gigabyte x570 said the fan isn't nearly as bad as was feared and he doesn't really here it, I think. But still... I don't really think I should spend the extra for an x570. Eh although.... part of why I got the b450 I got was because of the audio being good for mobo audio.... what I could have done is got that sound blaster with my $100 of deal and then got an x570 without having to care about the audio on it!
