It depends on the chipset you're talking about. Generally newer cards can go up to about 80 degrees celcius and remain safe. I'd say anything 70 degrees or below and you're fine. Oh and you're perfectly fine with your temperature dropping when you're out of the game. That's a good thing really since the graphics card isn't rendering anything to the display whilst you're tabbed out.
upâ¢stream. 1. toward or in the higher part of a stream; against the current. 2. directed or situated upstream. 3. against or opposite to the direction of transcription, translation, or synthesis of a DNA, RNA, or protein molecule.
Definition - What does Upstream mean? In computer networks, upstream refers to sending data from the client or local computer to the server or remote host. Upstream transmissions can take several forms, and the speed at which the data is transferred from the local machine to a server is known as the upstream rate. Upstream is the opposite of downstream, which refers to data transferred from a server to a local machine.
