CPUID HWMonitor is great tool. Nope, doesnt take a lot of resources.

Idle should be below 60'C, gaming should be below 90'C processor and 80'C GPU. (Room temperature)

Advisable to get cooler or gaming in air conditioned room.

Temperature also depends on game itself, more demanding games means much heat it will produce.

You're welcome. y510p has a lil bit better cooling system because its big compared to y410p. But the difference is not that significant. Just remember to lift ur laptop a bit while gaming so that the air intake doesnt get blocked. I always put books at the battery compartment. Then blow big ass fan opposite of the air exhaust. Even better gaming on air-conditioned room since its too hot nowadays.

Should be no problem bro. Playing BF4 on my Y500 GT750M usually got 50+ FPS on FHD. But i usually want my fps to stay at 60FPS, i manage to do it with some settings that i played, already forgot since i already sold my laptop. Haha. But all im saying its more than capable to play BF4 on Y510p.

But AC4 is not so good, i think AC4 is not really an optimized game. I tried many settings but cant really find the perfect fps so i straight away uninstall the game.

Cant remember bro i already sold my laptop. I usually tweak using my preference. I dont like it to be fix at high/medium/extra. Always mix to get good fps. Im a person who dont care much about AA/Aniso-filtering etc. i only want 60fps for my games. Haha. I even played on windows mode to get static 60fps. Its all about ur own preference as i said about AC4, the optimization is really bad unlike BF4 great optimized game.

Its perfectly normal if u played on room temperature.

First thing to do is to update your windows 8 to the latest update if u havent done so. I did this, then boom, windows upgrade available on app store.

He should buy gt755m, cant use with different model, wont work. price can check at garage sales if there is any.

Brands? What do u mean by brands?

Yezza only by lenovo.

Nope i didnt bother to buy the ultrabay as its quite expensive plus not all games support the SLI, not to mention the bugs, etc.

Driver problems, micro-stuttering, etc, most importantly not all games support SLI and can run smoothly. easy to say its not going to be smooth ride when ure on SLI. Many things to consider/tweak before u can play your games smoothly.

Haha its not about lenovo, nvidia itself.

It depends on ur windows version/driver version/game. U may want to google for more info if ure interested to buy one.

It is man! An i always used it to cool down my laptop after gaming as well. It cools down in a fast time.

Depends on game & setting. The higher the setting, higher temperature goes. Highest i got my Y500 is 86'C processor, and 80'C graphic if i remember correctly (ady sell my laptop ) Playing battlefield 4.

Really tempted to buy the V15 but knowing Acer i must molest the model and wait for review first. (The built in battery bothers me tho, preciously using Acer TimelineX gaming on that machine not more than 6 months battery kaput already).

I have molested the Asus, nice build quality but i didnt really like the screen. I hate anti-glare FHD screen, it just doesnt work imo. FHD screen must be glossy in order to showcase the HDness. For me la.

No bro, my acer 4830tg battery previously was very good 7hrs usually, but after i started gaming (dota 2) my battery deteriorate because of heat in about 4 months. thats why i dont understand why must they make a gaming laptop with built-in battery. But luckily Asus G551 battery is not built-in. I might be buying that out of these 3 altho the Acer specs is really tempting.

this is my temperature after one game of dota 2 (all max settings fhd)

quite good i must say, plus it runs quitely while gaming, my wife and son can sleep peacefully while im gaming.

My v-nitro temperature after 2 hours of battlefield 3 multiplayer. It runs smoothly and soo quiet. Im beginning to love this laptop. lol.
