No need for insults. If you're struggling to follow along, I can use crayon if that is more your speed.
There are many cars that cost less than $40k that are faster, turn better, etc than a $100k Mercedes, but do you see the Mercedes owner complain? No, he may realize the faster acceleration is a nice-to-have, but as an entire package, his Mercedes is better off than those lesser cars. He bought his car for the entire package. If he needed a car for the fastest 0-60, then he chose poorly again with the price he paid being irrelevant - he simply chose poorly.
Same here. You chose poorly given what you want to do with your equipment. If you knew you wanted to rotate what reads to be large images every 5 seconds, you would have been better off with a manufacturer that lets you get even better video GPU upgrades.
Remember, no one *forced* you to buy the Apple product. If you're unhappy with its performance (btw, nowhere did Apple guarantee your rotating images every 5s would be seamless), you can sell it and buy the other laptop that does what you need it to do.
