Just got a new GPU and wanted to know what you guys think, if its safe.
e6750 @ 2.66GHz (lowered from 3.0GHz in case not enough power)
ATI 4890 1GB DDR5
6-7 USB devices
I calculated this on the PSU site and came up to about 350 but when I go to the gigabyte site, it says 550w. my system is currently running pretty smooth. However, I upgraded from a 9600GT, windows rating was 6.9 for the 9600GT and 6.0 for the 4890... but I see the difference in gaming, anyone know whats up with that? Thanks guys.
