1
00:00:00,440 --> 00:00:08,160
since I first heard about the GTS 450 I thought it would be interesting to test

2
00:00:05,400 --> 00:00:14,360
this card because it is coming in at around a $100 price point I wanted to

3
00:00:11,080 --> 00:00:15,839
test it as a dedicated FX card so you

4
00:00:14,360 --> 00:00:22,439
can see I've got it configured here right now with the GTX 480 and then the

5
00:00:19,320 --> 00:00:24,439
GTS 450 because this is for fizx and not

6
00:00:22,439 --> 00:00:29,560
for SLI there's no need to install any SLI Bridges or anything like that and I

7
00:00:27,359 --> 00:00:34,480
am using a motherboard that has two PCI E6 16x slots so that's all you really

8
00:00:32,200 --> 00:00:39,040
need for FX now when you want to configure a dedicated FX card all you do

9
00:00:36,600 --> 00:00:44,399
is go into the NVIDIA control panel okay so you go into set physx configuration

10
00:00:41,920 --> 00:00:49,520
and then you select your physx processor so Auto Select would probably select the

11
00:00:46,879 --> 00:00:54,160
450 but I've gone ahead and selected the 450 anyway you can see the other options

12
00:00:51,600 --> 00:00:58,879
would be to run physx on the 480 run it on the CPU which is

13
00:00:56,239 --> 00:01:03,680
slow or run it on the 450 so then all you do is Click apply and that's all

14
00:01:00,640 --> 00:01:06,240
there is to it so you can see here it

15
00:01:03,680 --> 00:01:09,960
says yeah FX is running here and then the display is running here so that's

16
00:01:08,759 --> 00:01:14,159
fairly straightforward so what I'm going to do is I'll uh do up a little graph

17
00:01:12,479 --> 00:01:21,439
with some Benchmark results this is the same test bench I used for my GTS 450

18
00:01:17,759 --> 00:01:24,439
review as well as my gts450 uh SLI

19
00:01:21,439 --> 00:01:26,880
review well review and uh so I'm just

20
00:01:24,439 --> 00:01:31,280
going to go ahead and compare the 480 numbers I got without a dedicated physx

21
00:01:29,079 --> 00:01:37,680
card so while I was running physx on the on the 480 itself with adding the 450 to

22
00:01:34,520 --> 00:01:37,680
take a little bit of the load off

23
00:01:44,079 --> 00:01:50,399
it well I think based on the numbers the conclusion for this video is quite

24
00:01:48,399 --> 00:01:57,799
simple because you can see that a GTX 480 is a little over $500 after rebate

25
00:01:54,159 --> 00:02:01,039
on the ncx site and then a GTS

26
00:01:57,799 --> 00:02:05,840
450 is going to run you about

27
00:02:01,039 --> 00:02:09,399
$129.99 so you're adding about 25% more

28
00:02:05,840 --> 00:02:11,800
cost to your setup by adding a GTS 450

29
00:02:09,399 --> 00:02:17,160
on top of the GTX 480 that in theory you already

30
00:02:12,760 --> 00:02:20,200
own but you also get about on average a

31
00:02:17,160 --> 00:02:22,800
24.5% Improvement in performance so it's

32
00:02:20,200 --> 00:02:28,640
not actually very often on premium parts that you can pay an extra dollar to get

33
00:02:25,879 --> 00:02:32,120
an extra proportional amount of performance like usually see a point of

34
00:02:30,440 --> 00:02:37,599
diminishing returns where you're spending you know twice as much but

35
00:02:34,680 --> 00:02:41,040
you're only getting you know 1.5 times the amount of performance so it's

36
00:02:38,959 --> 00:02:45,560
actually a pretty good value from that perspective but the drawback is that out

37
00:02:43,720 --> 00:02:48,120
of all of the games that I have here on my Steam

38
00:02:49,440 --> 00:02:56,040
account I only have like two that support fizx so it's one of those

39
00:02:54,200 --> 00:03:00,879
situations where yes as a best case scenario a dedicated GTS 450 looks like

40
00:02:58,800 --> 00:03:05,239
a great value if you play games that are going to take advantage of it but if you

41
00:03:03,239 --> 00:03:09,120
don't play physx enabled games then you'd probably be better off saving your

42
00:03:07,000 --> 00:03:13,200
pennies to grab another 480 to run an SLI or finding some other way to

43
00:03:11,680 --> 00:03:19,440
increase the performance of your system so thanks for checking out my little

00:03:14,879 --> 00:03:24,200
mini review on using the GTS 450 as a

45

dedicated physx processor
