Performance – CPU
SiSoft Sandra measures the raw performance of the CPU under various computations, other components like RAM, graphics and hard drive have little impact on these results.



Examining these results, we can see that the Intel Core i7 720QM in the Asus G51J is substantially faster than the i5-540M and performs remarkably similar to the i5-661 desktop CPU. Going by these results, if you do a lot of CPU intensive operations and had a choice between a i5-540M and the i7-720QM, the choice is clearly the i7-720QM.

The Asus G50VT, which is the
The Asus G50VT, which is the predecessor to the G51J is superior in my opinion. It has a sexy red trim and that small OLED screen behind the keyboard. It can actually have more single core x86 performance than the G51J thanks to the X9100 Extreme processor, which you can overclock to 3.45, maybe 3.6GHZ 100% stable at full load.
The Forcecon fan is easily replaceable with a few screws, versus the G51J where I’ve heard you have to replace the whole heatsink to replace the fan.
