MSI GX660R Laptop Review
Obviously it would be both unfair, and entirely pointless, to compare the MSI GX660R to any of the desktop based systems we've tested. Firstly it's been a long while since we've tested a mobile dual-core or mobile GPU, and secondly because of the nature of desktop components and their lack of battery life or such vital heat considerations even a HD5870 will be more powerful than its mobile equivalent.
Without instant comparison there is less of "stating the obvious" going on here, but we can tell you that the little i5-460M really makes a mockery of its relatively small horsepower (pony power?). The Memory Bandwidth is particularly fine but the whole underpinnings of the GX660R will easily handle any average task that you throw at it.
PC Mark Vantage
Backing up the above is the results from PC Mark Vantage x64. Such a wealth of tests in a variety of situations and applications but the MSI GX660R never flinches. So often we see systems that are streamlined to a single task that looks good on the blurb, but the MSI will chew up anything you choose to do.
