Need advice

what settings are you trying to achieve ?

if its 720p30fps then you wont have to invest as much as opposed to like 1080p60fps

but your internet connection is likely to be a factor aswell with the 1mbit upload you will prob be capped at 540p resolution according to some posts about it on reddit

if you were to buy a completely new system you can try keeping the current pc and use that one as the streaming pc and use the new one for gaming

also whats your budget? if i know what you wanna spend i can give you some builds, your gpu is still fine, its just the cpu thats showing its age when hit with streaming and gaming

yes you would need to upgrade everything you have so a new mobo, ram and cpu


used is also questionable since youre going for something thats outdated already and theres no upgrade path

if youre on a tight budget its certainly better to get an older i7


if youre interested im actually selling my old 4770k + 16gb ram + z97 mobo

thanks for asking, this helps me too
