Hi there - I'm looking for advice cos I'm REALLY not a computer expert ! Following motherboard problems, my son's Asus G53JW-SX053V (bought Dec 2010 for 1200 euros) will be replaced by the electrical shop where we bought it. It's a "standard exchange" so should be exchanged for a computer with identical specs - as near as poss. They are offering him an Asus X53SV-SX750V (price 800 euros). We've seen the Asus G53SX-SX240V (price 1100 euros) which would also be an equivalent. What would be your advice as he uses it for gaming ? I just don't want to be fobbed off with an inferior product. Thanks for your help.
