Really? Surprised you were able to oveclock... I used to have a Dell M6300M Laptop, had a 2.5 duo core cpu, 4gb ram ddr2 @ 800mhz and a lovely 512mb 3600M Quadro gpu... Was fantastic and was even able to play Crysis on medium/high settings and 1600X900 resolution and get around 40fps, near smooth... However, I tried several times to overclock it, even using rivatuner but it would not work... This was 2 years ago, maybe now it is supported. It was a really amazing laptop, even when gaming to the max, hours and hours it never used to get hot nor made any noise, you would never hear the fans hardly.... Miss that laptop
