Mainstream performance at budget price.
The MSI CX640 wasn’t made to win benchmarks, as should be clear enough given its modest specs. I’ve compared it with the HP DV3 and the AMD Llano prototype unit we tested. Both have the same specs and cost about the same as well.
As far as pure processing tasks are concerned, the Sandy Bridge processor takes the cake, which means that for normal office and browsing work the CX640 will work just fine. However, when it comes to video games, things start getting choppy, with an average of 48fps on TF2 at Medium settings and 36fps in StarCraft II with Low settings.
With the “Gaming” preset, i.e. highest performance level, and with medium brightness I got just over 1 hour 40 minutes of battery life. With Nvidia Optimus on, where the integrated Intel graphics are the only thing working, I got just over 3 hours with net surfing and some HD YouTube videos.
Not bad, but then the MSI CX 640 is made for standard usage. If you’re in the market for a budget laptop, and do very occasional gaming, the MSI CX 640 is a decent laptop, but for the money you may find better offers from the competition.
