So i have a trooper that just wont quit. It's a Dell E521 and I plan on throwing a 6000+ 89w I found on Fleabay. Plug and play, Correct? I understand I need to make sure that my bios is up to date, anything else? Drivers? I'm still running Windows XP Pro SP3, it's just a movie, CADD, and word processing machine. Also what PS should i look for as I'm going to be needing more juice than 300 watts can supply, that has reared it's head after my HDMI card I've installed. Thank you people's, Jeff.
