Laptop Gaming

[Windows i7 920]

I'm getting some lag on Portal when graphics are maxed. I'm thinking my GPU is the bottleneck here, but here are the specs:

8 GB 1333 MHz DDR3 RAM
Intel Core i7 740 QM
ATI Mobility Radeon HD 5650 1 GB GDDR3
500 GB 7200 RPM HDD
1920x1080 OLED multi-touch LCD

Also, it gets pretty hot when I'm running like this. My laptop is barely thicker than a netbook which makes me wonder if a more powerful GPU will even fit in there.

There's no point thinking about other GPU's unless the 1 you have is removable which I doubt it is. The GPU (and subsiquent memory) is mounted on the mainboard.

The main problem is that 'mobile' GPU's just don't have the same power as their desktop counterparts and as such, running high performance games/apps will require more than the mobile GPU can offer (depending on in-game settings).

Saying that, you have a very impressive laptop and i'm now highly jealous but i'd look at lowering some of the in-game/app GFX settings and see if the problem still arises.

Another thing to note (and it's just me having my 'standard' head on lol) is that you need to make sure that all fan/heatsync ports have plenty of space as this can cause overheating.
