I called Gateway tech support over my ([FX7029E])’s [dead pixel]. And even though my Costco warranty lasts 90 days, Gateway will not replace a monitor with only 1 dead pixel. I can still return my desktop/monitor to Costco and get a new one. I have 90 days from from June 13th to get the monitor replaced from Costco (September 11th, 2008). I initially got the FX to replace my other [quad-proc box]. Up to [8GB of RAM] is supported by this desktop.
