What are the ideal idle and load temperatures for today's graphics cards? Preferably at stock clock speeds. I just got my computer back from the PC shop from being serviced under warranty. The HD 4850 was "extremely damaged" from constantly overheating, and generally being faulty. They took it out, and replaced it with an HD 5750 which idles @ 35-40 *C and runs @ 60-65 *C under load. How are those temperatures?
