I have exactly the opposite experience. I switched to Linux 13 years ago (Ubuntu + kde) and 5 years ago switched to Arch with no desktop manager, only xmonad. Works for weeks without poweroff, lots of exotic GUI applications opened, suspend it to RAM each day, resources are rarely filled. And, yes, I have 3 GPUs and program them all the time. It just works. Meanwhile, I have one OS X machine which is OK for multimedia and internet, but any programming on it sucks (compared to my Linux setup)...
