1
00:00:00,399 --> 00:00:07,160
so this is my usual thing where I compare the lengths and physical

2
00:00:05,200 --> 00:00:18,160
characteristics of a bunch of graphics cards so our feature dour today is the

3
00:00:12,360 --> 00:00:21,039
GTX 590 from NVIDIA this is a dual gf10

4
00:00:18,160 --> 00:00:26,320
card it is so it's SLI on a card we've seen dual GPU cards quite a few times in

5
00:00:23,680 --> 00:00:32,559
the past now now these are fully featured GF 1110s these are exactly the

6
00:00:28,519 --> 00:00:35,000
same gpus that you find on a GTX 580 so

7
00:00:32,559 --> 00:00:39,600
one of these so you might ask well how did NVIDIA manage to put two of those on

8
00:00:37,079 --> 00:00:43,719
one card and the answer is that they are actually downclocked well first of all

9
00:00:41,840 --> 00:00:48,399
they're bined very carefully for the best possible graphics cards or the

10
00:00:45,760 --> 00:00:55,000
chips to put on it and then second they are actually downclocked so they do have

11
00:00:51,840 --> 00:00:57,239
less performance than a single GTX 580

12
00:00:55,000 --> 00:01:03,600
but they more than make up for it by having two of them okay so this card has

13
00:01:00,680 --> 00:01:10,640
an 80 mm fan in the middle it has heat sinks on either side for each of the

14
00:01:06,960 --> 00:01:13,200
gpus it has three DVI outputs with one

15
00:01:10,640 --> 00:01:17,400
mini DisplayPort so those three DVI outputs this is another unique thing

16
00:01:14,759 --> 00:01:22,479
about this card allow it to support 3D Vision surround or just plain surround

17
00:01:20,280 --> 00:01:28,400
off a single card that is three displays over DVI so that's pretty cool it does

18
00:01:24,759 --> 00:01:32,280
support quad SLI because it has one SLI

19
00:01:28,400 --> 00:01:35,640
finger and it needs two PCI E8 pin power

20
00:01:32,280 --> 00:01:37,320
connectors so let's just contrast it

21
00:01:35,640 --> 00:01:41,880
against these other cards in terms of length it is an 11in card so I'll just

22
00:01:40,000 --> 00:01:48,520
show you guys that there you go it's an 11in card so

23
00:01:45,040 --> 00:01:52,079
you compare that to the radon HD 6990

24
00:01:48,520 --> 00:01:57,000
which is a 1T that is a 12 in card and

25
00:01:52,079 --> 00:02:00,079
to the GTX 580 which is only a 10 1/2 in

26
00:01:57,000 --> 00:02:02,560
card now the 69

27
00:02:00,079 --> 00:02:07,960
oops I'm going to wreck my tablecloth here the 6970 is almost 11 in and then

28
00:02:06,439 --> 00:02:14,360
if we go all the way down into kind of the mainstream cards then we end up with

29
00:02:10,000 --> 00:02:16,519
a GTX 560 TI and that is a 9in card so

30
00:02:14,360 --> 00:02:24,360
just for contrast you can look at what it would take to fit a GTX 590 in your

31
00:02:20,120 --> 00:02:26,920
case versus a GTX 560 TI sort of

32
00:02:24,360 --> 00:02:31,440
mainstream single GPU card now there are other considerations to bear in mind as

33
00:02:29,160 --> 00:02:35,640
well this fan needs to have a fair amount of clearance around it because

34
00:02:33,080 --> 00:02:40,200
with two fmes in there there's a fair bit of heat being generated so you need

35
00:02:37,120 --> 00:02:42,319
to make sure it has adequate ventilation

36
00:02:40,200 --> 00:02:45,280
and yeah that's pretty much where I was going with that you got to make sure it

37
00:02:43,840 --> 00:02:50,040
has adequate ventilation you also need to make sure your case has overall

38
00:02:47,879 --> 00:02:54,080
adequate air flow in it because half of the heat is going to be exhausted

39
00:02:51,360 --> 00:02:57,640
directly into your case out this side and then a fairly substantial amount of

40
00:02:56,159 --> 00:03:01,280
it is going to come out into your case this way and then the rest will be

41
00:02:59,959 --> 00:03:04,879
exhausted so this is going to kick a fair amount of heat into your case and

42
00:03:03,599 --> 00:03:09,760
you got to make sure you have lots of fans to keep things cool thank you for
