Remain with Intel if you need speed to compile programs and stuff. Otherwise, yeah, the AMD CPU is a considerable bottleneck to CPU heavy stuff. RAM upgrades can help the GX60 but it'll still slow down when doing REAL CPU taxing stuff.

Gaming + programming below RM4k and remains cool. Acer V7 (3.7k)? Also, the Illegear RE15: Nvidia 765 and 15 inch FHD screen for about the same price. That's prolly about it for "not so hot" laptops suitable for gaming.

Alternatively you can get the RE13/GE40 but both runs HOT, at least at full load.

RE13 runs slightly colder, has the 765 + beautiful FHD IPS screen, slightly thicker body and a 4-hour battery life. GE40 on the other hand, runs hotter, has the 760 + 900p TN (read: considerably less beautiful) screen, thinner body and a 6-7 hour battery life.

As for others, err Lenovo Y510P SLI? 1 hour battery life, FHD screen and TWO 750m GPUs. Of course it runs hot as well unfortunately. Alternatively, the GE60, but it also has bad battery life and runs just as hot with only a single 765.

IINM your best bet is the Illegear RE15 for that budget. Maybe you can also consider the MSI GE60 with the nvidia 750 which is even cheaper than the GE40 (3.4k), but the RE15 has better specs for only an extra 300++.

Very true for some other pastes as well. Thankfully my Xigmatek Freezing Point isn't corrosive, though it's probably not as effective as IC.
The GE60 with 750 ALSO comes with just an i5, so yeah it'll be LOTS cooler. It's a lot cheaper too at 2.8k now (on offer).

Still holding on the RE15 as my recommendation for now.

@MSI-NB: Thanks for the clarification boss.

it come with SteelSeries  but only BLue backlit

Edit: you can purchase SteelSeries backlit with full led light show cost you RM 450-600

GE40 no backlit, or any lights besides the indicators and the dragon eyes for that matter.

@MSI-NB: Regarding the DDR3L, we found out the hard way that 1.5v is not really well liked by Haswell.

It's 2.9k or something only now, got promo (not sure for how long). Intel i5 only (dual core IINM) and 750, no backlit. Should run much cooler on load (compared to the i7/765 GE60 and the i7/760 GE40) due to the i5 and 750.

Supposedly no. Not sure though.

GE60 20E have baklit(blue only...)  ask MR.storm88 if he can confirm this

yes.. improve. with ram upgrade must be 16GB 1866mhz ram

I'm not too familiar with the GE-series so I'll only comment on the GX-series. Hehe...

Barring the weak CPU, I like everything about the GX60/70. It has almost everything that made GT60/70 nice (e.g. cooler boost, dynaudio, amplified headphone jacks, subwoofer, Killer LAN, same nice casing, etc). In fact I was considering this model too. The one I looked at has mSATA SSD (not sure if its 2x 64GB RAID 0). So bottom line, its a very good deal for the money you paid for. I'll look pass the weak A10-5750M if budget was a constraint.

As mentioned by experts here, pick the 1866MHz memory modules in pairs and you'll increase the performance by quite a bit. If one is daring enough, try to source for A8/A10 engineering samples so that you can OC them. That would increase the GPU utilization.
In my humble opinion, the 1866MHz memory modules does indeed improve APU performance especially the integrated graphics as its bandwidth starve. If you're able to in some way make your programming/rendering applications to also utilize the entire APU (meaning the graphics) for GPGPU, it'll be better.

As for the CPU itself, you need to read about the Piledriver core architecture to understand its weaknesses. There are only two cores in the CPU. Each core has certain areas/resources doubled/shared to allow two threads to run. Giving you 4 logical cores. Sort of like Hyperthreading but its not. Essentially we're talking about performance of around 80% of a real dual core. Because the resources are shared. Also Windows 7 initially had issues with core utilization because it sends threads to physical cores. Sort of like how Windows has problem with early Intel Hyperthreading.

I'm not sure why AMD is going down this pathway, but I believe its to prep the design for GPGPU. For now I wouldn't look at AMD until Steamroller (Kaveri) is released. Why? AMD changed the core configuration because it knew of the weakness of Piledriver. The arithmetic unit has been doubled this time, no more sharing. Only the FPU is still shared. Also the integrated graphics core is now GCN and no more VLIW4.

AMD's future will be bright because Jaguar has been adopted in two major consoles (PS4 and Xbox One). All those x86 console games will be ported back/in between x86 PC platform. And heavily optimized for AMD hardware which is essentially APU architecture.

You want power (but with CPU bottleneck risk for compiling programs) = GX60

You want balance and low heat = GE60 750 (prolly).

You want small size and battery life = GE40.

Still standing by my recommendation of the Illegear RE15 though.

Please note the RE15 got some sort of issue now (sound card static). So I have to stop recommending it for a while, please save up for the GS70 (or get the GE60 i7 750) if possible if you need your laptop ASAP.
