Processor-i7(series not mentioned)
clock speed-1.3 GHz
1 GB ATi Mobility Radeon HD 5870 ddr5
I assume that ATi Mobility Radeon HD 5870 ddr5 is better than 2GB NVIDIA Geforce GT 650M DDR3.....But i m on a doubt whether the processor clock speed of MSI GX660 i.e 1.3 GHz will be enough for high end gaming??
The processor of the MSI GX660 is the i7-740QM at 1.73GHZ, with turbo up to 2.93Ghz. This processor is overclockable on the MSIGX660, so you can force the turbo boost to stay activated. It is also Quad Core, WITH hyperthreading.
The GT 650M alas has DDR3 memory, which makes it vastly inferior to the HD 5870 graphics.
