is this true, it's really available under 60k?? Hows the build quality of this lappy man.
If the OP wants gaming, he needn't waste time with XPS if the GX640 is available.
Temperature
Many of MSI's previous gaming notebooks have been notable for their excessive overheating, and readings of over 90°C for the processor and 100ºC for the graphics card were no rarity. The cause quickly becomes apparent when you take a look inside the laptop - a single fan for the entire case and only one heatpipe for the CPU and GPU. MSI must be unconcerned by such issues, or it would long ago have granted this case its long overdue retirement.
The situation with the GX640 is as follows: while the Core i5-430M is still relatively well cooled in idle mode at around 50°C, the temperature under full load rises steeply to 85°C.
But it is the Radeon HD 5850 that is truly worrying; after a half hour of all-out usage, Furmark showed an exceptionally high temperature of 107°C. This is not going to be good for the life expectancy of the components. It should also be noted that these temperatures come from our second review machine - in the first one we were given, the temperature of the GPU shot up to 110°C in a very short space of time, at which point the GX640 expired. It was probably that the cooling plate of the graphics card did not fit 100%.
The external temperatures were also cause for complaint. Under a heavy system load, the palm rest area reached an uncomfortable 36.9°C, with the keyboard reaching an even higher 38.2°C. On the
underside of the laptop it gets as warm as
51.9°C, so it would not be a good idea to have the GX640 on your lap for any length of time
Conclusion:
The GX640 has been optimised for high performance, with little thought for anything else. The results are obvious:
high internal and external temperatures (with the GPU reaching 107°C) and a lot of system noise. Further weak points are the GX640's
disappointing sound quality and its not very bright display, with particularly limited viewing angles. And why MSI is still using this keyboard in its models is a mystery; it is insultingly bad, even after a long time spent getting used to it.
But the 15-inch gaming notebook also has some good features. For instance,
the compact body with its high-quality brushed aluminium surfaces, the very fast hard drive, good touchpad, and wide range of ports, and the black gaming mouse that comes with it.
Its biggest strength, of course, is its breathtaking gaming performance - for a notebook, that is. Thanks to its high clock speed and lightning-fast GDDR5-VRAM, the ATI Mobility Radeon HD 5850 even triumphed over Nvidia's top model, the GeForce GTX 285M, in our benchmarks.
When all is said and done,
we would not feel comfortable recommending the MSI GX640 because of its many failings. If you are looking for a more balanced gaming package, you might like to consider rival products like the Asus G73J. But it must be said that the GX640 does not fail to deliver first-class gaming performance.
Review MSI GX640-i5447LW7P Notebook - Notebookcheck.net Reviews
Since the GX640 has HD5850 which is not switchable even idle power consumption is high resulting in low battery life and system fan always turned on.
This laptop is for people who are interested in the cheapest and best mobile gaming and nothing else.
Its better to wait for SB proccy with a HD6xxx series since this is switchable graphics and thus might bring down the noise and power consumption down by a bit.
