I'm planning on getting a new videocard for my other machine (not in my profile) and have decided between a Palit 9600GT or a Sapphire HD3870. Which one would be better for 1024x1080 resolution? (my monitor is 19" and I won't go higher than that res.) My other primary concern is if the NZXT PP500 PSU in that machine would be enough for either the 3870 or the 9600GT. IIRC the power supply has dual rails with 16A on one rail and 17A on the other. Also I have heard about black screens after playing for some time on the 9600GTs, but that they are on the EVGA boards. Do the Palit boards have this problem? Thanks for your time and help.
