I received my Gigabyte P34G a week ago, and although it has a few things that could have been better, I'm nonetheless seriously happy with it.
The cons:
- Sometimes erratic fan behavior under low load circumstances (under full load it is fine imo: with speaker volume at 50-60% you hardly hear it, let alone with headphones);
- Keyboard tray (made of aluminium) and certain keys have a bit of flex, and the screen bevel is made of cheapish plastic - none of it is all too bad, but it does contrast with the overall build quality and appearance (it definitely looks like a high-end product);
- Screen is slightly grainy due to non-glare coating, and also has a bit of a yellowish hue (which should be fixable with a good color profile) - other than that, the screen is outstanding as far as viewing angles, brightness, contrast, color depth etc. are concerned;
- The keyboard layout is not bad, but could be better: it lacks dedicated Home/End/PageUp/PageDown keys - the cursor keys double as such through the Fn-key, which is inconvenient given its location to the left of the space bar. The keyboard also has half-sized Up/Down keys. So that's something to keep in mind of you want to use it for actual work as well (I use it for designing/developing my own website, it it does take a bit of getting used to it). Lastly, key presses result in a cheapish 'dup-dup-dup'-sound.
The pros:
- Performance is amazing given the size/weight of the machine: in 1080p, Battlefield 4 runs smoothly in high (SP) and medium-high (MP), as does Sleeping Dogs with everything maxxed out except anti-aliasing. During normal use, the machine is very snappy and responsive (Lightroom 5, web development), a pleasure to work with;
- Good storage capacity: mine came with a 128GB SSD (max 512GB), a 750GB HDD (max. 1TB) and 8GB RAM (max. 16GB);
- As said, the screen is stunning;
- Decent trackpad (although to me it feels cold and - too? - smooth to the touch: my previous laptop, an Alienware m11x, had a textured, all-plastic one, so it might be a case of getting used to it);
- Good connectivity: 4x USB (2x USB 3), VGA, HDMI, Ethernet, Card reader;
- It remains cool to the touch even after a long and intensive gaming session. Also, as soon as you close down a game, fan speed decreases drastically;
- I know it's a matter of personal preference, but I really like the sleek, stylish and modest design (and despite that, it does turn heads, I noticed - especially the screen gets a lot of reactions). The used materials generally add to the overall impression (except those few things I mentioned in the Cons-section) of a generally good build quality - it's a well-engineered machine;
- It's incredibly portable at 2,1" thick and 1.7kg of weight. A useful (fake leather?) sleeve is included, although in the end you might want to get something a bit more study/protective.
As far as gaming on it: I'll always keep playing certain games (like FPS and other games that pretty much require mouse/keyboard controls) on my desktop, but for relaxed gaming sessions playing games that do well with a wireless X-Box controller (3rd person, sandbox, racing) the screen is more than adequate (2-3ft distance). Gaming with my laptop on the coffee table while chilling on the couch works remarkably well!
