System specs are below. I plan on upgrading to a 4870 card or better towards the end of the year. What UPS and with what specs should I get for this setup? It doesn't have to run for more than 10mins max under full load since what I'm mainly concerned about is power fluctuations. Over the past few weeks there have been some power fluctuations/brownouts that have casued me some concern. I know nothing about UPS except for APC. I have looked online and they are rated by VA and watts. Which numbers and features should I pay attention to? What are some brands I can trust and others to avoid?
