Video games: RetroAhoy – Quake, overclock your video card, Nvidia GTX 1070 performance review

RetroAhoy has created a new documentary in regards to the video game industry. In a mix of video game history, gameplay explanations, excellent storytelling and great graphics, Retro Ahoy explains why Quake was the game that changed the face of video games for ever.

The way the levels were created, number of enemies, fast-paced action and the fact that you could mod the game have transformed Quake into a game of reference, a legend. I’ve played the game in the 90s and early 2000s and it was a great experience. It was in a time where computers like the one we have today were a chapter in a scifi movie.

The world has changed a lot and Quake made sure to change the video game landscape for ever. Quake forever.

Getting to things that are more close to today, JayzTwoCents explains why we should overclock our video cards: the video card producers limit the performance on purpose, but give you tools to overclock so that you can use the card at its full capacity. It will shorten the life of a card from 5 to 4 years, for example, but most of us will buy a new card within 2-3 years anyways, so it is a good bet.

What about a performance review for Nvidia GTX 1070, one of the newest kids in the block from Nvidia? There is such a review and the numbers say it aloud: it is the best card around for 1440p gaming. Go get it:

Computer fun: how a CPU is made, aspect ratios, case recommendation


A CPU is build in a very strictly controlled environment where the transistors are build by simply building them layer by layer though a process called photolithography. Today we have CPUs in which the transistors are 14nm big. It is an incredible step since the first ICs in 1947, but basically a CPU is build from dumb things which let current flow. A transistor does not know anything about how the entire CPU much like a cell in our bodies doesn’t know or understand how the entire body works.

A book is recommended in this case: But How Do It Know. It is about how a CPU is build. It is build from dumb things which, when taken together, can do a lot of work.

Noe, let’s get to monitors. Today’s aspect ratio is 16:9, but it wasn’t always this one. 4:3 was very popular with CRT displays. If you remember those displays, then you know they could offer great color contract and images.

Also, once we’re here, you might want to take a look at what video cards are best depending on the display resolution you have. A great shift int he way the guys at Tom’s Hardware are making their reviews.

Now, if you want a quiet and a cool case for your computer, then why not get your hands on BeQuiet Silent Base 600 PC Case. Linus reviews it below:

PC games: gaming laptop NP987OU2 G, Sapphire AMD R9 380X Nitro, XFX Radeon R9 Fury. Bonus: light-field camera


The Sager NP987OU2 G gaming laptop costs about $3700, but you have the performance of a gaming desktop computer in it. You can play whatever you want given the specs. The one from the video above has desktp Intel processor 6700K and a Ddesktop video card Nvidia GTX 980,

The base specs cost about $2300 and can be seen below:
– 17.3″ Full HD IPS Matte Display with G-SYNC Technology
– Nvidia GeForce GTX 980M 8GB GDDR5
– 6th Gen Intel® Core™ i7-6700 Processor
– 8GB DDR4 at 2133MHz
– 1TB 7200rpm SATA2 HDD
– Windows® 10 Home 64-Bit Edition

Yup, you can pretty much do anything with it? Would I buy such a laptop? Nope. I want the comfort of a big 27-32″ monitor.

What to know how do some of the best AMD video cards stack up against each other? Check in the video from below Sapphire AMD R9 380X Nitro vs 380 vs 390 vs 970:

What about an XFX Radeon R9 Fury Overview from Newegg TV?

Bonus: how does a lightfield camera work? A lightfield camera is a camera that stores am image which can be later on focused on different points in the computer. It uses a set of microlenses place before the camera sensor in order to store more information about the image and to also offer the ability to change the perpective of the image a bit.

What is HBM, the new memory type used in video cards [High Bandwidth Memory]

GDDR5 is history. Or at least it will be history, as HBM, High Bandwidth Memory, is able to provide at least two times more throughput than its predecessor. GDDR5 is over 7 years old now and has the memory chips attached directly to the video card’s PCB, around the GPU. If you needed more GDDR5 memory, then you would need more such chips inserted in there and more connections to the GPU.

HBM solves this issue by stacking the memory chips on top of the GPU package, the area that holds the GPU, so it doesn’t need anymore extra space than the GPU already needs. It stacks the memory in 3D RAM dies right next to the GPU which makes communication with it much much faster.

With 4 stacks of HBM you can get about 1TB/s transfer rate. Right now only AMD Radeon R9 Fury series has this type of memory, but many other video cards with HBM will be available soon.

Tips and tricks: how to overclock a video card [video]


Jayz2Cents creates another great video for gamers. This time is about how to overclock a video card. I am the guy who usually doesn’t like to get into this king of stuff and thus I usually buy a good video card which can do all the things I want without having to tinker with any overclocking abilities.

What tips and tricks should you follow when overclocking a video card:
– make sure you do overclock because it is an extra headroom that you get for free, much like upgrading your GPU
– use apps like MSI Afterburner to help you overclock AMD/nVidia graphics cards
– try to set the temp as high as possible and don’t touch the core voltage until you see the test benchmark (like Valley Benchmark ) crashing

PC gaming: 3 GTX 970s vs 2 GTX 980s and what is M.2


Linus tested 3 GTX 970s vs 2 GTX 980s and found out that it is better to use 2 GTX 980s. Why? Because you won’t need to consume that much power with only 2 cards instead of 3 and the cards will not heat as crazy. Using three cards in SLI mode will result in the card that is positioned at the middle to heat up unnecessarily and make a ton of noise in return.

If you really have the money to spend buy one good, premium graphics card. The GTX 980 costs about $550 and the GTX 970 costs $330. Both use GDDR5, have 4 GB of VRAM but the processor clock speed vary and also the CUDA processors.

All in all, the GTX 970 seems to be the better option cost-wise.

Now, let’s learn about the M.2 the port on the motherboard where you can insert your M.2 SSD. Newer SSD can be inserted in the M.2 slot and you will have a ton of connection speed because of this. You will not need any wires to connect this SSD to the motherboard so you got some increased write/read speeds.

How to choose a graphics or video card?


Jayz2Cents is here to the rescue. He first explains what those 8 – 12 manufacturers of graphics card do to those cards and then gives us details about what matters. Most often than not, some manufacturers will choose to add a ton of features to the base graphics cards someone like Nvidia prints specs out for.

Nvidia gives out the specs, but manufacturers are free to add whatever they want. This is why you see that the video cards may have different fans or different VRAM.

Now, to what matters: the amount of VRAM the cards nowadays have is typically 2GB, but you may need more if you have monitors that run above 1080p. MSAA might consume large amounts of VRAM but you woudl not need it if you run even at 1080p.

Usually when its about graphics cards I look for these things:
– GPU – the more the better, needs to be above 1GHz
– VRAM – it needs to be GDDR5 and at least 3-4 GB
– bits – usually you will find with 128 bit BUSes, but I’d choose those with 512 bit

A card like the one from above would cost easily above 500 USD, but it makes magic.

How to find the best LCD gaming monitor?


Tech quickie, while not always definitively correct, has some basics covered and this time we learn about how to find the best LCD monitor to enjoy a good gaming experience.

I sound like a marketer ie a broken freaking record.

In any case, since I’m too lazy to really write down all the details, here are the top 3 things to look for when buying a gaming monitor:
– response time below 2 ms
– refresh rate over 60Hz or even 120Hz or 144 Hz
– input lag/display lag below 10 ms

Well, the ms in there is for millisecond and 2 or 10 of these tiny measurements don’t really count. Refresh rate of 120Hz for gamers?! Hmm, the human eye can see 26fps or at 26Hz so the extra wouldn’t really be needed.

In some situations, when there is some shooting going on and some explosions you may need to have more fps, but not that high. In any case, if you have a video card like Radeon R9 270X(affil link) from AMD you should be fine. Couple that with 8GB or RAM and a quad core or i7 processor and you have a modest to decent gaming PC.

Having issue what monitor to choose? Doesn’t really matter if you get close to the numbers from above. Make sure you have the right video card instead.
