0:11 Am I the only one who gets confused by AMD's naming scheme? Do you know how
0:14 many times I've had to reshoot part of a video because I was like, today we're
0:18 going to be having a look at the 7970 versus the 7790 or the 7770 or the 799.
0:24 I mean, they're all there's only two numbers that change. They should just
0:27 call him like the, you know, rejuvenator
0:31 and like the like the the the the
0:36 Bushmaster or like things like that. They should have names like pocket
0:40 knives. Anyway, this is the 7790, which
0:43 is slightly better than the 7770, but
0:46 not nearly as good as the 7970. This is one from MSI. It is an overclocked
0:51 graphics card, which basically means that it comes with a higher default clock speed than a stock one from
0:56 directly from AMD would if you could buy something like that and the year wasn't
1:00 sort of 2006. Um, it has 1 gig of GDDR5,
1:04 although this GPU is available with more memory, and I might recommend stepping
1:07 up to the 2 gig one if it doesn't cost that much more. It's uh PCI Express 3.0,
1:11 DirectX11. It supports AMD Infinity, all those good things. And here we are. So,
1:19 we've got a piece of foam here that keeps it in place. We've got a graphics
1:22 card here that puts your games in their place. And we've got a couple of little
1:27 adapters. I remember when graphics cards used to have a lot of different stuff in
1:30 the packages. And honestly, I don't really miss those days because nowadays
1:35 they come with exactly what you need and not a whole lot more. Now, this card is
1:40 not based on exactly the same core as the 7770 and the 7750. And it's also not
1:46 based on the same core as the 7850 and the 7870. In fact, the rumor on the
1:51 street is that this would have been an 8000 series card if things had gone
1:57 slightly differently for it and it would have been more like a replacement for a
2:01 7770 as a next generation architecture. And it kind of aligns with that rumor in
2:07 terms of the performance. Although I can neither confirm nor deny whether that
2:10 was ever true or not because quite frankly I actually don't know. So, there
2:15 you go. I don't even know why I bothered talking about that. MSI includes little
2:18 dust covers on all of the connectors. So, you don't have to worry about any kind of corrosion or like um you know,
2:24 biohazardous leeches
2:28 eating the connectors while it's in transit or whatever else could possibly
2:31 happen to a DVI connector while it's sitting in a box. Uh, it also gives you
2:34 if you're ever storing the card, like if you want to keep it on like a trophy
2:38 shelf, like if you want a tournament with this card and you wanted to like
2:41 put it somewhere and keep it on display, then you could cover up the connectors
2:44 so that they don't get covered in dust or something like that. You know what? Why don't I just stay focused from now
2:49 on? So, we've got a 100 mm cooling fan that uses MSI's propeller blades. So,
2:54 you can tell from the uh the tip on there. So, these are designed to push a
2:58 little bit more air flow than standard blades. Remember, cooling graphics cards
3:01 is a bit of a challenge because of the form factors that are necessary. This is
3:05 a two slot card and so you often end up using thin fans that aren't really able
3:10 to do much in terms of static pressure. You also often end up with very dense
3:14 fin arrangements. So, it's incredibly important to design a fan that is able
3:17 to deliver ample pressure in order to push air through these fins and actually
3:22 cool the GPU as well as the other components of the card itself. The
3:25 shroud is plastic, but it has kind of a nice look to it. MSI has really done a
3:29 great job with their styling over the last few years. So, there's a solid
3:32 aluminum block here that is attached to some aluminum fins up here. And then
3:37 there are two heat pipes that appear to be direct touch heat pipes. So, those
3:40 are contacting the GPU core directly. And they then carry heat out to the
3:44 aluminum fin arrangement here as well as here. Now, you can see into the back of
3:48 the card there's some components that look like they're going to get some incidental cooling from the fan itself
3:53 as well as your single six pin PCI Express connector. Then over here we've
3:57 got another heat sink that's attached directly to the PCB. That's going to be
4:01 for your VRM. So they're actually bringing power into the board at the
4:04 back and then turning it into the different voltages that the board itself
4:08 can use that the chips on board can use right over here. So that's some sort of
4:13 fancy routing, but it's not the first time we've seen this, particularly on
4:16 these shorter length PCI Express cards. So you can see the card itself isn't
4:20 much longer than a PCI Express slot. And
4:24 I think that's pretty much all there is to say about that. Okay. Cooler. Yep. On
4:29 the back, we find we're going to be exhausting some of the air outside the
4:32 case, but like most custom cooled cards, this one exhausts most of the air inside
4:36 the case. So, make sure you have adequate ventilation. Two DVI ports and
4:40 HDMI and DisplayPort ports ensure that this card is able to support AMD's
4:44 iinity. So, that means multiple displays, and they really do have the
4:48 best driver support for this guys. If you want a game across multiple
4:52 displays, it's probably a good idea to grab an AMD card. However, don't buy
4:57 this one. If you're going to buy this one, buy the 2 gig version because even
5:00 older games once you start playing at extremely high resolutions stand a
5:04 pretty good chance of utilizing all of that video memory that they have
5:07 available to them. 1 gig is really not going to be enough for you there. It
5:11 does support Crossfire. So, there's a single Crossfire connector on the top of
5:14 the card, meaning it's going to be compatible with two-way configurations.
5:18 And this is something that I haven't really seen on an MSI card before, but
5:21 it looks like they don't want you removing that stock CPU cooler. So, your
5:25 warranty will be void on this card if you remove that and take off the cooler.
5:30 However, it should be noted that these low-end cards, particularly the
5:34 aftermarket PCB ones, are usually not compatible with liquid coolers anyway,
5:37 particularly full cover ones. And if you're going to spend the money on a liquid cooler, a full cover blocks 100
5:42 bucks plus. So, I wouldn't be doing it on a card that doesn't cost that much
5:45 more than $1 to $170.
