I have used WGC for a long time now. I do not own a high-end computer and the only issues I have ever had were slower updates. I don't see what everyone else's issues with it are. It is running in the background right now and only using an average of 32 MB. There are also 2 error monitor processes running with it at around 2 MB each. Steam and all the Windows processes running use far more memory then WGC.
