I have no idea actually, i didn't follow GPU pricetag for quite some time, only recently i wanna buy GTX1060 6GB for my 2nd pc but only realized it was sold out everywhere & for those have stock they selling like skyhigh price, i remember my friend bought one earlier this year about RM1200. Last week went to Lowyat was informed by shops the stock only keep for system build, but allowed to purchase GTX1050ti the below outright.

with 6 x 1080ti up there.. usd32/day.

but zotac and msi not ngam... now talk talk him wtb his zotac 2.5k each. hahahaha.... 

Negative pressure will lead to higher amount of dust in the case. Positive air pressure will push air out instead of air being sucked in from wherever possible. Correct me if I'm wrong though.

Actually, with GPU Boost 3.0, most users can have overclocked card, without even manually overclocking. So, it's different, but better to almost majority of the users.

Most people recommend MSI Afterburner.

normally i terus hentam the figure from reviewer such as guru3d or anandtech. lazy to increase 10mhz by 10mhz.
the below is from guru3d OC settings:
Core Voltage : +100%
Power Limit : 120%
Temp. limit : 92C
Core Clock : + 100 MHz
Memory Clock : +600 MHz (= 9,216 MHz effective data-rate)

1. Just drag your power limit to maximum - link with Temp.
2. input the figure as above.
3. run games / heaven / 3dmark
4. IF Stable > gratz -> want to find ceiling clock -> increase by 5mhz or 10mhz or 20mhz.
    IF Crash > decrease by 5mhz and re-run Heaven benchmark. (Repeat if still crash until it won't crash)
5. Require to do so for both Core and Memory clock.

Normally i find max clock for Core clock first then only start to adjust memory clock after hentam the number above. 

**AT MOST - HEAVEN / Benchmark crash only. with the lock enforce by Nvidia, we won't able to fried it sadly.
***Not include you hack and mod the Voltage, which the above did not do so

Lastly, have fun wasting time to find the Ceiling OC your card can do and repeat seeing the same old shit benchie 

MSI AB - my trusted OC software....
bcoz i'm used to it and its simple.
