I am not exaggerating, even if you can get a new monitor for $75, guess what, 20$ calibrated display is still miles ahead in value, (which you still will never recoup), (calibrated)1440p+ and or up 120hz+ you may recoup even 50% for the next 3 years (new), if you buy something that goes into the trash when you replace it, you have made a mistake.
Just to be clear, before we devolved into discussing whether choppy (implied mouse)movement and frame cap of 60 per seconds was not important (is my english really this bad?), I recommended that the op either;
A) Buy only the tower now (and wait for a good deal on a higher refresh rate monitor)
B) Buy used 1080p 60hz for the low low price of up to 10(-20) freedom dollars (and discard or keep as secondary shit monitor when buying a proper panel)
I cannot see this as bad advice under any circumstances, it's just a question of reclaiming value.
