By the way, there is another excellent Sandy bridge laptop available from ASUS, A53SJ at a very reasonable price:-
Core i5 2410Q
4 GB DDR3
500 GB HDD
15.6" LED backlit display @ 1366X 768
GT 520M 1 GB GDDR3
3 USB, 1 eSATA
Altec Lancing Speakers
Free gifts incude Laptop Bag, USB Speakers, USB Keyboard and 1 headphone
all the things are coming @ 37.5K
I came to know about this laptop in a showroom Yesterday & then returning home i checked about GT 520M
According to my knowledge GT520M is an entry level graphics & it is a class3 graphics card(according to notebookcheck.net).
You can't play modern games like Battlefield Bad Company 2 even in medium details.
GT 420M is way better than this.
420M is an entry level solution. HD5650 is a midrange gaming solution but can run games with full details.
BTW which laptop are you referring to? Dell XPS series vs Sony/Acer?
Between
Dell Insipron 14R(core i3,3gb ram,320gb hdd,HD5650,14")
Acer 5742G(core i5,3gb ram, 500gb hdd, GF 420M,15.6")
But some are saying that Acer laptops are built on low quality & not durable
Is that true
