Hi, i need help in upgrading my imac 2011 21.5”. i really like this computer and i already did some upgrades: I installed quadro k2100m 16gb ram, ssd 128 and hdd 120 in dvd slot, my next step should be processor, because i5-2400s is very slow. I was thinking about buying i7-2600s because it’s natively supported but xeon e3-1270 seems more powerful and cheaper, but i’m not sure if it would work in my situation, will 205w psu be enough for k2100m and xeon? is it plug-n-play? do i need to instal something? i use macos monterey with opencore. also i heard that sleep is broken, how is it broken? is there any solution to fix it? hope someone will help me. thanks.
