Hi guys, it has been several months since I've started thinking about a gaming rig upgrade. After many researches and browsing, I sticked up to this build, which was originally suggested to me by @PsychoticLeprechaun (who I thank) and has ended being my favorite of all the builds I've seen. What do you think of it? Are there any other builds with similar price (€600) I should give a look to? About the lack of the OS: I've seen that on sites like Kinguin they sell Win 10 keys for €15 and they seem to be safe purchases, so... Regarding sound card, is it necessary? Does it improve sound quality in gaming an evident way? Being pretty much into music (I play the bass) is it recommendable for me to have one?
