actually how long is your warranty? if under warranty, and you dont need it on a daily basis, send it, have them fix it for you.I suspect this might also have something to do with your GPU driver, or even anything that you have recently installed( excluding games, but might be some software that comes with games though ) clashing with any background running app. Whenever stuffs like this happen, try using driver sweep and install back the driver that you first ran your laptop with. Secondly, about repasting the laptop, it also depends on what thermal paste you will be replacing them with. If you are replacing them with some random budget cooler master paste, I dont think it would help a lot. Try using diamond IC if u really want to have your laptop last longer. It helps a lot.

alternatively, instead of throwing your money into #AppleMasterRace, try what other forumer already recommended, illegear. Even with 860M i think the GPU is also better than your current one, and the cooling is way better than most the laptops out there as well.

if you main reason is video editing, then indeed there's a point for going MAC, but problem is how much would u be paying for it? As I recall a MAC with a decent graphic card would easily cost 5k


Some technicians are honest about the flaws etc when u send in to service. If you service gonna take 3 weeks to a month, normally it means you're sending in to a smaller SC, and they send your laptop to their main SC to repair. Best to just ask them for the main SC near your area, go there yourself and repair it. Last time my Asus tablet took only 3 days to fix a main board problem, when the sunway pyramid branch says 2-3 weeks time.

Honestly cleaning heatsink and repasting is something u can easily do, just google the disassemble video of your laptop, be very careful and follow exact instructions and you'll be safe. just research around what's the best thermal paste, have 4 hours to just slowly do everything, and enjoy your laptop with much cooler temp biggrin.gif

850M is good, but it's running DDR3 or GDDR3 so bear in mind that it will be bottlenecked by memory speed when you're running at full HD resolution. As i recall there's a 850M with GDDR5 as well, but it's harder to find. For the case, if the laptop is not runnig full HD, just the dell tru life resolution, then this should be a very decent gaming machine.

What is the consequences of this? Sorry noob here  rclxub.gif

the consequence is that if you are playing in FHD resolution, and havnig high texture, you reach a point where your performance would be rather terrible, your fps will be staying at a certain number and it cant go much higher even if you overclock your GPU core clock, or drop some of the shading settings, because your memory is not capable of sending that much data fast enough to your screen. On scenario like this, you can still opt to overclock your vRam memory speed to push the bandwidth higher, but it would not help much against the much faster tech like GDDR5

in short, if you wanna game on FHD, always prioritize GDDR5 over GDDR3.
