Need to Upgrade my Exisiting Config [Greedy HAF]

[The Sorcerer]

Sandy would have pulled it off. This is too close for comfort TBH even if it does pull it off. I always prefer to utlitize 80% of a psu's potential. Cards+ rig+ memory+ fans+ hard drives comes into play as well. Wise move to ease up and grab a 1000w unit. Also there's a unit from Antec Quattro. You can check up on that too. Sexed out AC adapter. But do make sure you have a good surge protector and the main AC plugs are good enough as well.

2x 570GTX for that resolution is pretty much like bare essentials.

A friend of mine who uses IPS panels told me about this.

Display lag - Wikipedia, the free encyclopedia

The thing with SLI/CF is that the image processing induced latency increases as the data is transferred back and forth between the GPUs.

It has nothing to do with the screen's response time. Display lag is a thing of past now and and newer monitors are free from this issue. Its has said fast paced games are often plagued by display lag of a monitor for eg. tekken.

Now i have played tekken on my hdtv which has an ips panel and it showed no signs of display lag. So i think it not much of a concern for op here.

See this:

Display lag is a phenomenon associated with some types of LCD displays, and nearly all types of HDTVs, that refers to latency, or lag measured by the difference between the time a signal is input into a display and the time it is shown by the display. This lag time has been measured as high as 68ms,[1] or the equivalent of 3-4 frames on a 60 Hz display. Display lag is not to be confused with pixel response time.

Its from the same link you provided.

And here's another:

Anecdotally, display lag is significantly less when displays operate in native resolutions for a given LCD screen and in a progressive scanning mode. External devices have also been shown to reduce overall latency by providing faster image-space resizing algorithms than those present in the LCD screen.

So you see, running at 1080p or higher has much lesser display lag issue and is non-existent tbh especially in progressive scanned mode.

Megamind: no. It will be close to rated draw and OCing will be a PITA. You want an HX1000 or something man.

Nvidia recommends TX950 for 580 SLI..

The AX850 is not a TX950.

It is obvious you have been unable to grasp what I said.

The problem is that vs. TN panels the images appear at a later time to you.
In single player there wont be much difference but in multiplayer it can be a live or die situation. If your opponent is able to get updated a few moments before you about the surroundings then he has the upper hand. This is most noticable when both of you have similar pings to the server you are playing on.

Also I never said pixel response time. I said monitor response time. The amount of time taken by the monitor's chips to convert the data sent to it by the GPU.
The manufacturers note their native resolution response times btw.

IMHO the Dell SP2309W makes a good buy even now due to its fast response times, good colour reproduction(98% of the normal colour gamut) and amazing 2048x1152 native resolution, making it sharper than any 23" Ultrasharp monitor lol.

It will be easier to grasp if you explain properly and not in bits and pieces.The thing in bold is display lag right??

Why are you saying specific IPS panels are prone to display lag? Can you give some fitting proof? Why TN panels have the edge?? I'm sure it has nothing to do pixel response time which is same as monitor response time( both are the same thing and not what you say). It was clearly written in that wikipedia link you provided.

Give proper reasons to validate your points so that we can really learn from them.

Can you justify the above and give proper reasons why this happen on specific ips panels and not in tn ones?

Ok Guys...Good News AX850w can kick those 580 SLI.

Lets go by the reviews first...

Legit Reviews : Click Here

Other CF & SLI Cards Power Consumption.

*www.legitreviews.com/images/reviews/1488/power-consumption.jpg

Even i ran Extreme Power Supply Calculation from Outervision with OCed Processor & every thing maxed out. Theoretical value suggests 780Watts & 850w is a safe limit.

A Single GTX580 draws almost 12v, 40A making a total of 360w at worst case, whereas in SLI it draws squeezes out almost 600w. So I'm safe now.

So lets continue with displays & ups.

I didnt say "specific IPS panels". These things have to be experienced.
Its that images will appear faster in TN panels vs. IPS panels and so you can react earlier. In fast paced multiplayer split-seconds count.

In single player there should hardly be any difference while gaming.

If the OP can wait, 120 FPS 3D Vision IPS panels will be coming in a few months. These should defeat all the current TN panels.

Deb extreme outervision is hardly a reliable source.

Account for your OCing also.

.

There are no 120fps panels. I think you meant 120hz panels supporting 3d. I asked you to give some fitting proof to justify your claims and you still didn't give any.

Afaik, display lag is a thing of past and now, no monitors are severely affected by this phenomenon. There won't be any slower reaction in fast paced multiplayer games unless you don't have a fast enough internet connection.

There won't be any lagging due to the display itself. All newer monitors are free from it.This has been seen and experienced.

He wrote that pretty clearly didn't he? The decoders aren't going to be equally fast in every monitor make?

The amount of time taken by the monitor's chips to convert the data sent to it by the GPU.

I won't conclude by saying TN will _always_ be faster than IPS. Things will obviously vary.

Playing Tekken with your controller isn't going to prove anything about display lag. You have to play a FPS game and a fast one that is. I've played Quake 3 all my life.

For my LCD panel which "claims" 5 ms response time:

(remember doing this earlier, I used to be around 180-190ms)

For my IPS LCD TV which "claims" 2 ms response time

Try out yourself: Human Benchmark - Reaction Time Test

React when the colour changes.

Might as well try this out: Response time - Lagom LCD test

This includes every latency. From your brain's reaction to the click, time taken by the PC to register the click etc. Plus, I was using mini DP to VGA converter for the LCD monitor.

One more off-topic post in this thread = a three day ban. Sort out on PM. Thanks. We aren't catering to the OP with this discussion. Don't think we as hobbyist online gamers are affected as such.

@ d3p5kor

My suggestion is to stick with AX850 and opt for next gen cards. They will consume much lesser power for sure. Don't go for 3gb 580sli now. You will be using more than 80% power of your psu which isn't a bright decision. Waiting is good. Till then use one monitor and game on your existing card.

 

[Extreme Gamer]

UCP-900 is as sturdy as TX-950. It is also discontinued IIRC.

AX850 is very strong but I would like to stay at least 150W away from rated wattage. remember that efficiency takes a U-turn past rated wattage.

 

[d3p]

Yes, but i will stick to AX850 & let the PSU burn for whatever reason. Its under warranty for next 6 years. So its fine, let it be a risk.

Will it be a wise move to sell off the i7 920, Gigabyte UD7 & Dominator 6GB CL8 kit for Sandybridge ???

 

[Extreme Gamer]

It may not burn. Its OCP will kick in and may not let you run two 580s.

If it burns it could kill your other parts too.

 

[d3p]

If thats the case then Kepler or Radeon HD7xxx is worth to wait.

But again, what about a Single GTX590 ??

Reviews are good, but noisy as well as a Hot Piece.

 

[max_snyper]

^^the next gen gpu's are not drastic improvement over the current gen gpu's
the only thing is they offer more performance on lower power requirement.....!
if you are ready to wait for 1~3 months then u will be able to get these gpu's.

 

[Extreme Gamer]

You can get a 590 but its 1.5GB/GPU, not true 3GB.

Wait for kepler (Southern islands will come out at least 2 months before it). Also wait for new Monitors.

 

[MegaMind]

It may not burn. Its OCP will kick in and may not let you run two 580s.

No chance of that, as OP is not planning on running CPU & GPU @100% load 24x7...

 

[Extreme Gamer]

That doesnt mean OCP cant kick in.

 

[MegaMind]

One should always have some headroom left for the PSU..

But AX850 for 580 SLI + OC'ed CPU is still Safe..
All units are not the same, just to let you know,

AX850 overload tests

Check this.
*www.guru3d.com/article/asus [...] i-review/8

800+ watts for SLI. They also overestimate the watts by a bit for some reason.

Also read this

 

[d3p]

@Megamind: Yes thats a nice piece of info.

But what EG tries here to explain is, it might be safe to squeeze out 1000w or more than the rated Power, but not a good idea for longer run as the efficiency or the lifetime of the components might be effected.
