I guess which one to choose depends on your definition of "light gaming". Your "light" might not be my interpretation of "light"

Personally I would prefer the XPS13 more because of the much better and comfortable keyboard, carbon-fibre built and also non-glossiness design (apart from the screen, of course ) which are good features to have on a ultrabook used for business (and at the same time not too ugly) haha
But it runs on an Intel HD3000 iGPU, so don't expect too much gaming from the XPS 13...
You can consider the relatively cheaper HP Folio 13 as well, its sort of similar to the XPS13:
13"
Hp [Ultrabook] Pavilion dm3-1001TU (Folio 13), i5-2467M + Intel HD3000 + 128GB SSD@RM2999[1.49kg], W7HP


The ZenBook UX32vd would be better if you're looking into playing some relatively more "hardcore" games But that's about it... the touchpad is not as good as that of the XPS13 and personally I feel that it'll be a bit too flashy for a business notebook

Other ultrabooks capable of relatively better gaming performance:
14"
Acer [Ultrabook] M5-481TG-53316G12, i5-3317U + Nvidia GT640M LE (28nm Kepler) + 128GB SSD@RM2899[1.85kg], 6GB, W7HP
Asus [Ultrabook]S46CM-WX023V, i5-3317U + Nvidia GT635M + 24GB mSATA + 500GB HDD@RM2399[2kg], 4GB, W7HP
Dell [Ultrabook]Inspiron 14z, i5-3317U + AMD HD7570M + 32GB SSD + 500GB(5400rpm)@RM2599[1.87kg], 4GB, 500GB(5400rpm) *no VGA port, OD
HP [Ultrabook] Envy4-1043TX/1053TX, i5-3317U + AMD HD7670M + [32GB mSATA + 500GB(5400rpm)]@RM2599[Beats][1.75kg], 4GB, W7HP
Samsung [Ultrabook] NP530U4C, i5-3317U + Nvidia GT620M + 24GB mSATA + 1TB HDD@RM2999[1.81kg], 6GB, ODD, W7HP
Toshiba [Ultrabook] Satellite U840-1008X, i5-3317U + AMD HD7550M + 32GB mSATA + 500GB HDD@RM2999[1.7kg], 4GB, backlit keyboard, color: silver, free RM200 petrol voucher

Yeah the i3-2365M would be able to handle those just fine
Some other alternatives:
14"
Dell
[Ultrabook]Inspiron 14z, i3-3217U + Intel HD4000@RM1599[1.87kg], 4GB, 500GB(5400rpm), Ubuntu Linux 11.10, *no VGA port, OD
[Ultrabook]Inspiron 14z, i3-3217U + Intel HD4000@RM1799[1.87kg], 4GB, 500GB(5400rpm), W7HB, *no VGA port, OD

These are running on IB ULV-processors, which are faster than the SB ones

I would avoid recommending netbooks as those are really a bit too small for most people.
Can consider these:

No problem man
well, the thing about ultrabooks is that almost all of them will run hot because of the slim design which reduces effective airflow... its unavoidable, hence manufacturers charge an unavoidable higher warranty price for ultrabooks.

As for the Envy, it will run hot as well, and its a fingerprint magnet despite its awesome looks LOL... My past experience with glossy laptops (Qosmio F60 and Satellite M500) has really turned me off against glossiness XD

here's a review on the unit (spec may differ): http://www.laptopmag.com/review/laptops/hp...14-spectre.aspx

I don't really like to reocmmend HP Compaq to people... they seem to have cut too much corners in this particular line of laptops
At least Dell's Inspiron 14 are broadly-speced; as in even the ones with higher spec will also use the same chassis. And also the warranty support is better

Minds sharing your usage and budget?

Bang-for-buck is too general... the RM3.3k Sager NP6110 is the best bang for buck gaming laptop, but I think that's not what you are looking for

Almost any laptop can play Dota man

Nope

The GPU of the 14R SE is better than the GT630M in the G580

Apart from the G580, you can consider this one as well

That is the thing, which is why I specifically say that its good to have when
i) you have the budget
ii) you are getting a >15.6" notebook (they have better cooling; and they are not really known for good battery life in the 1st place)

is that means 14" not really suitable for i7, but i though14" i7 power consumption and heat dissipation still the way better than core 2 duo right ?

[/quote]

Quad core i7 generates a lot more heat than i5 and core 2 duo
It all depends on whether you need the i7 or not (based on your requirements, you don't need it). If you insist on getting one, then getting a 15 incher would be better, especially so if you don't mind getting a 14 or 15" notebook

1. OD = Optical drive. The Inspiron 14z has it
2. Yeah it should be better than those standard ones, but not by a lot

Here's a review on the unit (specs may differ): http://www.laptopmag.com/review/laptops/de...n-14z-2012.aspx

No you don't need i7
But if you insist, just go ahead with it, its your choice at the end of the day

That one is RM3.5k?

Not sure whether you know what you are talking about
Almost all processors in the market now are Ivy Bridge ones

As for the i5 processors, go for the normal ones (non-ULV); i5-3210M for your case.
Avoid ULV ones i.e. i5-3317U

The final choice is yours

I really wanted the S300, but stupid Lenovo Malaysia only brought in the lowest end model, which is pathetic considering there are even i5-3317U variants abroad
Anyway, you have a rough estimate on the performance based on this unit with the same processor: http://www.notebookcheck.net/Review-Lenovo...ok.82831.0.html

The A45Vd has a much weaker graphic card..

In terms of GPU performance, GT630M = AMD HD7670M
