You can find some reputable re-sellers at LYN garage sales forum
Some of them do delivery service like devour, numbertwo ...
If you prefer those who has shop in LYP, then look for re-sellers like rickyrich, itking ... (contact them first so that you could negotiate price and confirm stock 1st ... )
(I'm not related to these re-sellers )

Could you tell us where you are going? For certain countries, it is better (more choices, cheaper ... ) for you to buy there.
If you buy in Malaysia, you better look for those brands that give you international warranty. Praying that your laptop last long is not a very good bet

You Acer 4741G is probably using the 1st gen i5 CPU (i5-430M ?), and the Nvidia 310M GPU as you mentioned.
Is it giving you the performance that you want for the games you play? If yes, then better don't change laptop lah. Just increase the RAM (8G stick ~ RM200) or change HDD to SSD (256G ~ RM600).

If you are not happy with the performance of the Acer 4741G, then things have move along quite a bit
Haswell is the code name for the 4th gen Intel I-core CPU. Solely on CPU performance, it is more frugal on power usage compared to the 1st gen (so battery running time on same battery capacity will be better), and performance also is >20% better clock for clock vs 1 gen. That will not has much impact on the games you play or MS Office though.
Haswell also has much better IGPU now. It now come with Intel 42/44/46/50/51/5200 IGPU, performance of some of these is already on par (or exceed) the Nvidia 310M

For your budget, you could probably get a laptop that spec with Nvidia GT630M to GT740M, which outperform the Nvidia GT310M by a LOT. So you will definitely see lots of improvement in the games you play.

Haswell is a generation refresh cover the full spectrum of Intel I-core CPU, definitely will has choices within your budget range.

Since you are not in a hurry, strongly suggest you wait a bit. Come back again say in 4Q13, most models should be refreshed with Haswell CPU already. Or you could attempt to snatch a bargain when brands clear stock for Ivy Bridge spec laptop during 3Q13

woke up by the babies, can't get back to sleep

Actually, I'm not in IT sector, just an enthusiast
Raymond, on the other hand, currently work in a IT shop

you can see the inside of MBA 2013 in these tear down screen shot. The fan is tiny, but it's there
http://www.ifixit.com/Teardown/MacBook+Air...eardown/15042/1

you need to scale down your expectation, moving from desktop to laptop Desktop replacement laptop are expensive.
To perform at the level of GTX650 Ti, you will probably need GTX770M or GTX780M
And for mobile CPU, only i7 is quad core.

For your budget, your choices are:

Asus
G55VW-S1216H, i7-3630QM +Nvidia GTX660M (2GB) + (1920x1080)@RM3999[3.78kg], 4GB, 1TB(5400rpm), W8

iinm, nothing in Malaysia right now.

K46CB-WX060H, i5-3337U + Nvidia GT740M@RM2199[2kg], 2GB, 750GB, W8, 4-cell, OD

From Asus, pretty much only that one.

Lenovo
Z400, i5-3230M + Nvidia GT740M@RM2099, 4GB, 1TB, W8; 2 years warranty

Another interesting choice is this:
Toshiba
Satellite L40-AS109Xb/G/W, i5-3337U + Nvidia GT740M@RM2199[Onkyo], 4GB, 750GB, 3 years local warranty

The Toshiba come with 3 year warranty, and both the Lenovo and Toshiba has ODD.
Lenovo and Toshiba warranty service is better than Asus
Both are ~ 2.2kg, not as light as the K46CB

Windows RT, not compatible with lots of window desktop apps
Have its usage and niche, but I strongly suspect WinRT is dead (Microsoft just took a huge write-down in its latest quarterly result on WinRT).
When 22nm Atom coming out later this year, tablets from Windows camp can run full W8(.1), defeating the whole purpose of WinRT

Btw, in case you didn't know, all the devices in the market running WinRT just have major price cut (>30%) lately Draw whatever conclusion you like

Check how many RAM slots are available in the laptop. If there are unoccupied slots, you could put more stick in.
Hard to say, most of the non-performance RAM work quite well together. The more "on the edge", the more fickle they become. Anyway, if all the sticks are not of the same timing, (and if they work), they will run at the slowest timing.

GT750M SLI run close to GTX765M for games that support SLI. (big difference between GTX765 vs GTX765M )
Y500 is still ivy bridge, Y510p (should be in Malaysia soon) is spec with Haswell just like Y410p.
