I see. But so far I used all the software that you mention, with the increase performance in CPU and GPU do help a lot. Especially when i compare a i5 and i7 laptop, the rendering and processing speed is differ a lot. While for the graphic card, many ppl would said that it not that important but i do see the difference when the upgrade of GPU. For instance a GT540m compare with GT650m both with same CPU and ram, the processing speed for autoCAD, revit, sketch up, photoshop, etc, the speed had increase a lot. So i think that GPU also play a very important role in this field as well other than CPU and ram. Perhaps the balance in between these would be more suitable.

Maybe instead of recommend you the model directly, I would like to recommend you with the spec

CPU- Go for i7, i5 would not that convenient when dealing with heavy file load.
Ram- At least get 8GB ram but if can up to 12GB is preferable
GPU- In the current trend, get at least performance with GT650m and above. Below this might not worth for the value and hard to fulfill your need and may cause you to change your laptop in short time frame.
HDD- You can try to upgrade to SSD. Even with all high spec CPU, GPU, ram but with a normal rpm HDD, the performance would be affect very much. If possible, look for laptop that provide 2 HDD slot. Another option is swap with your optical drive.
Screen- Look for FHD, it will maximize your window space especially many ppl like to use autocad with latest mode and not classic work space, those interface take up a lot of space. With FHD, it become neat and small so even with 15 inch, you still have a lot of work space. Or you may connect to external monitor. But for this field, at least get a laptop with 15inch and above is better

basically these are the need of spec for this field. So good luck in your hunting. Btw, you are studying or working?

I see.

Regarding on the ram yes. It can support. As 8GB is just like just enough. So why dun we provide extra yet the price for a ram of 4GB is not very high.

While for the FHD, even it will become smaller with the icon and the menu bar, but the empty space is increase so it just like the window in AutoCAD, with all the menu interface on, it take up a lot of model space. So that when you look at a plan, you need to scroll or zoom in and out a lot with a smaller resolution. All the icon and menu is big. For FHD 1920x1080, the menu icon become small so the model space for the plan  is bigger thus you no need to scroll that much and enhance the productivity. The most obvious software would be Sketch UP, you will see a lot of different in the model space when comparing in these 2 resolution. So go for FHD and you wont regret about it.

And i had send you a link on the seller so pls check your pm.

Thanks alot.

Working, dude.

CPU - i7 is suffcient for current uses.
RAM - 12GB is alot. Can the CPU support that much RAM? Mostly are running at 8gb.
GPU - advice taken
HDD - Ugrade to SDD, agreed. I would probably do away with the optical drive as it is occupying too much space and less usage. My sis just bought a new laptop which she also traded away the optical drive.
Screen - Care to explain how FHD increases the workspace? If it becomes smaller, isn't it harder to see?

Currently looking at Y500, coz i'd rather purchase a laptop which comes is assembled by 1 manufacturer rather than assembled with different parts of different brand. Later owuld face compatibility and space issues, not to mention overheating issues.

Lastly, any recommendations on where can I get a good price for a laptop? I'm currently living in Shah Alam. Tq

I've tried out the Lenovo Y500 this afternoon.

The keyboard is soft, good to type on, much better than Y580, though I'm not sure if it smoothens with excessive use, as in the key alphabets fade off easier, and if there is a replacement for the keys.

Screen, FHD, though I did not look closely to tell the difference with Y580 and Y400.

Ram, it seems that the original set comes with 4GB. Is that so,  i mean for a laptop of that specs? Means i would need a few hundred more for an upgrade to 8gb or even 12gb.

2 yr warranty, which means i would need to top up a few more hundreds for an extra year warranty.

Graphic card, Dual Nvdia GT650M, 1 built in and 1 more mounted on ultrabay slot. It seems that Y580 only has 1 Nvdia and the other 1 is intel graphic card.

Hard disc, Sata 500gb. To upgrade to SSD would be RM 200 for 120gb, which I doubt if its even enough for normal usage.

Outlook and built, simply stunning.

And No, Autocad does not support SLI. According to experts, it does not even accesses the GPU, but rather the processor itself, which I find it weird.

Autocad depends heavily on cpu processor speed

Yes, like I said, Autocad only draws its juice from the CPU and does not go through the GPU. So its kinda redundant for me to get a laptop that emphasizes on GPU. Will have to reconsider my options given that its not necessary for me to max out my GPU power. I would rather channel my money to processor, RAM, SSD and monitor instead.
