When all the dust settled, the ASUS G51VX is a very good performer, easily hitting the top of the class compared to other notebooks I have tested. One of the machines weakest points is its battery life, which is not even an hour in my benchmarks.
The real problem I have with the G51VX is its price. At nearly $3,000 the machine simply doesn't offer the performance to justify the price when compared to the sub-$2000 Gateway P7808u. When you are talking bout a $1,000 price gap between the two machines, the Gateway P7808u stands out.
ASUS crams lots of performance into the G51VX, but it crams a big price tag in there, too. At about $800 less the ASUS G51VX would be a much more attractive gaming machine.
