I bought a 3700X in September, two months after they were released. (took a while for prices/supply to stabilize) I have never had any problems with it. Linux problems only crop up with heavily integrated custom systems. Typically laptops that cram a ton of shit into the smallest possible space, and then try to work around incompatibilities with extensive driver customization. Typically, if you can wipe a system's hard disk, install Windows on it, and only install drivers from the chipset manufacturer rather than from the brand of the laptop, and everything works, you'll be fine. But if your Lenovo laptop has a Realtek wireless chip in it, and the driver downloaded directly from Realtek is flaky, but the driver downloaded from Lenovo works, it will be flaky in Linux too. The laptop brand isn't going to spend the money to monkey with some weird driver because they like spending money - they're spending that money because they're doing something the chipset maker doesn't support. These problems almost never happen on desktops with full sized ATX motherboards. First of all, the expectation is that you'll buy a copy of Windows and the motherboard manufacturer doesn't have the opportunity to slip in their pile of custom drivers and other assorted crapware into a custom Windows install. Second, with plenty of space on the motherboard there's no need for fancy tricks that fall down when you look at them funny.
