Assuming you're considering in between these two:
Asus N55SF-SX331v, i7-2670QM + Nvidia GT555M + 1600x900 + Bluray@RM3599[Bang & Olufsen]; USB3.0, Sonic Master subwoofer, 2 years international warranty

MSI GE620DX-675, i7-2670QM + Nvidia GT635M + (1920x1080)@RM3599, 8GB, 750GB, 2 years warranty

I'm not sure whether the SX331v really comes with 1600x900 (as stated in the brochure or not), you should check, if it comes with 1920x1080, then both laptops are equally good
Otherwise, the MSI is better

For work and multimedia, the Asus would be a better choice. Larger screen resolution is a joy to view and has pretty great sound system.

The MSI is a good choice if you don't mind gaming in HD resolution.

MSI isn't as popular. Only recently have they started to promote aggressively.

msi for sure, they got their hidden beauty. trust me

@XeactorZ, do look out for this model 1st:
Asus N55Sf-S1515v [black], i5-2450M + Nvidia GT555m (2GB) + 1920x1080@2899[Bang & Olufsen]; 750GB (7200rpm), USB3.0, Sonic Master subwoofer *EOL-ed

its way more worth it even though its slightly older... performance-wise, both are basically the same in terms of GPU (GT635M = GT555m rebadged), but the S1515v has a faster HDD as well as FullHD screen

for more information bout n55 sf/ sl ? this thread owner using n55sf i5 which rm28xx too. look at his reviews, maybe you will be poisoned soon.

haha brilliant ! 

after this month if i'm not wrong aha, based on ur budget 3k below, .
i heard lenova y480 releasing soon. below 3k for the others u may wait longer, and i5 ivy, more longer.

I think the only difference between those 2 is a slight different in graphics and huge difference in audio. The MSI has 7.1 ready audio hardware. Make your pick.

Yes. Check out the reviews.

2.5k?    go for the msi as i said (the look is just a eye deceiving, trust me hidden beauty~~ bro. look into my eyes! =>    , very serious rite?!
2.5k for getting ivy with good spec .. .. .. ivy 5 ? haha of course you can if you can wait longer. if i'm 2.5 budget, will save a bit more go for the msi.
pc fair right? get a bunches of staff too.

^ asus n56 and n46 launch already ?

Probably Ivy Bridge and Nvidia Kepler 

^ some more look better than the previous models and with backlit keyboard

Ivy Bridge processors doesn't bring about very significant performance boost, especially for those looking for gaming laptops..
However its a different story if one is looking for a normal subnotebook or ultrabook without a dedicated GPU
