this video is brought to you by the Intel Core i5 4670k unlocked processor
add an Intel 520 series SSD to your Haswell system for unbelievable overall
performance welcome to my unboxing and first look at the GeForce GTX 770
windforce OC version according to Gigabyte here from Gigabyte this is as
you may or may not have figured out by now a GeForce gtx770 it is overclocked
and more importantly than the factory overclock it has gigabytes windforce
cooler so their windforce cooler uses a triple fan design each of these fans
being 75 mm in diameter as well as one
of the beefiest come on out there we go as well
as one of the beefiest heat sink designs that I have ever seen but I'm not going
to let you feas oriz on the card just yet I'm going to make you look at oh wow
look at them accessories is that two Molex to PCI Express adapters wow wow
one six pin 18 pin so cool next oh is
that a driver disc wing and quick graphics card
installation guide although if you don't like gigabytes installation guide then you can check out my installation guide
which is a video which is obviously better cuz videos are awesome all right
so the cooler itself there's your three 75 mm fans all right there is your
massive array of heat sink fins so check
this out you have a huge block of fins over here on the left a huge block of
fins over here on the right you can also see from the side over here there are
five heat pipes coming out this side so two of them are 8 mm heat pipes so these
are massive thick heat pipes and then the other four of the heat pipes that
are on the card itself are 6 mm heat pipes so you can see which direction
they're all going in actually five of them go off this way and then one of
them loops around and comes out this side in order to effectively spread the
heat away from the GPU itself and then onto the rest of the components now
Gigabyte has done a couple of unique things to improve the efficiency of the
cooler so number one is they have added this triangle shape is what they're
calling it it's not quite a triangle because it has a flat top and I hope you
guys can see this so if you check this out there's a flat top there and then
there are angled uh angled pieces that are going to cause the air flow to be
more directed than you would have normally seen with a windforce cooler in
the past so what this will do is it'll take the air flow and it'll bring it in
through the fan and then drive it up this way and down this way as a opposed
to causing an additional turbulence by having it interfere with the air flow
from this fan which will then be directed this way and this way this guy
over here is kind of on his own but this serves two purposes not only to cool the
GPU core itself with all the heat that it's getting from those heat pipes but
also to cool the vrm components so that is the voltage delivery our voltage
regulation modules all of the stuff that turns that 12vt power that comes in from
the PCI Express connectors into something that a GPU and memory and all
of that can use now speaking of memory it has a full memory plate so that is
responsible for cooling the 7 GHz gddr5
memory that you'll find on pretty much any GeForce GTX 770 graphics card and
Gigabyte has gone with a modest overclock on the GPU core so it is well
in excess of a of over 1 GHz however
this is the trick when you have a very solid cooler on one of these graphics
cards because of GPU Boost 2.0 and the way that it works where it actually
monitors your voltage your temperature so bear that in mind for later the power
usage as well as the clock speed the cooler you can keep the card the closer
to within your temperature limit you can keep it the faster it will actually
perform which before GPU Boost 2.0 was never really true so even though one
Factory overclocked Card might come with clock speed a and one might come with
clock speed B the one with the better cooler may actually be running at a
higher clock speed more of the time particular if you're in a hot region now the card
is very standard in terms of its shape and size it is a twoos slot card in
spite of its 450 watts of heat dissipation which we saw a demo of at
computex it is real it is actually a thing which I thought was pretty darn
cool it's got the standard layout of ports so you've got two DVI ports as
well as one HDMI and one DisplayPort Port you've also got two fingers for SLI
up here giving you compatibility with two-way three-way and potentially
four-way SLI although NVIDIA does doesn't spend much time talking about
four-way SLI anymore because the reality of it is it doesn't really scale that
well down at the bottom of the card we've got a PCI Express 3.0 16x
connector and then you can see that this is a completely non-reference card so it
uses gigabytes Ultra durable concept which basically amounts to beefier
components and improved efficiency less heat output and all that good stuff that
you expect from an aftermarket cooled card up on the top of the card we've got
the six pin PCI Express power adapter as well as an eight pin PCI Express power
adapter and a pretty cool sort of lattice work looking shroud that is
attached to the one thing that I'd say is kind of non-standard about this card
and that is the wind Force branding up here at the top but as long as you don't
have a very narrow case and something like a side panel fan that might
interfere with this you're not going to have too much difficulty now I wouldn't
be completely finishing this video if I didn't mention some of the things that
it comes with so it has adaptive vsync which allows you to take advantage of
the benefits of vsync as well as the benefits of not using vsync it also has
has the GeForce experience which keeps your drivers up to date and gives you
suggestions for what settings to run your games at and later on is going to
be adding Shadow play which is pretty cool it just will use the built-in h264
encoding on your card in order to record the last 20 minutes or less or however
much you want of your gameplay so that you can save it for gameplay videos
later it also supports 3D Vision as well as NVIDIA surround so that is up to
three displays in surround and one auxiliary display and I think that is
pretty much it don't forget to subscribe to lus Tech
