I recently had to RMA my Gigabyte GA-790XTA-UD4 AM3 motherboard for the 2nd time since I purchased it. Just as happened last year GBT fixed my motherboard the day they recieved it & I got it back the next day.
I included a list of the issues & every single one has been resolved.
Having dealt with several other manufacturers over the years I can honestly say this is by far the best service I every experienced (Thermaltake
cough, cough ). (I can't speak for Gigabyte in other countries though).
I just thought I'd post so if any users are considering UK RMA's for niggly faults & wondering whether to bother. On my experience you'll probably only be without your board 2-3 days so go for it.
