(2) GTX 295 SLI question

[texan1962]

Is this over kill?

 

[theAnimal]

Yes. 4 GPUs do not scale well. Unless you absolutely have to play with maximum settings and high AA and AF on a 30" monitor.

We'll need specs and screen size (resolution ofc)

And I for 1 don't agree with quad sli, at the money you pay it doesn't yield what its supposed 2.

Example 2 260s will scale a generous 80% in some cases, 50 % in others, but it scales.

Quad on the other hand has a very one of a kind thing, it can decrease your fps in some games. Plus min frame rate problems become apart of the DNA.

Lastly, They are driver dependant. If the company chose not to support quad anymore, your screwed ofc you can say that regular sli too, but thats not going to be given up since it does what it supposed to with out the hassle.

Also i would look into the 4870 X2, if you haven't chosen your mobo already. 100$ cheaper (very common these days), more vram, and dx 10.1. 10-15% slower, but hell of a better deal for the money.

No you will be happy with two of those bad boys.

Nice facts^?

I have a 24" hi def monitor...also a 55" LCD 20 feet away. I would it be with Blueray, newer games etc...? Rest of system: Can a 1000 watt PS handle them?

Rampage II extreme
i7 920
V10 cooler
9 gb corsair dominator
GTX 295 1 or 2 of them
1000 watt PS

 

[L1qu1d]

100watts should be enough, I believe that 295 GTX Quad consumes around as much as 3 280s (285s), so yeah, 1000 should be enough.

I suggest Corsair 1000HX if you don't already have 1.

 

[texan1962]

After looking at benchmark reviews I can't justify +25 f/s and heat for $500. I would have to fork out more money for liquid cooling.

How is that possible? It is 2 55nm GTX260+ put together, while GTX280 is 65nm.

According to xbitlabs a GTX295 only uses ~214W.

 

[L1qu1d]

The new Nvidia 55 nms really do around 10-15 watts better than the 65 nms, they massively improved idle watts from what I remember and temps, but not really full load.

You said GTX295 uses as much as 3 GTX280 or 285.

Power consumption of video cards only.

well the thread is about quad, so it was a typo that was corrected if you checked 1 295 GTX I beleive consumes a bit less than 2 260s, if I'm no mistaken and close to 2 280s (about 50-100 watts depending on the review). When under full load (full system load).

Why the Quad sli 295GTX consume only 657watt? Is that means a good quality Power supply 700watt with lots of Amps can handle two 295GTX?

 

[L1qu1d]

no, thats just an average rating sometimes, don't grab bare minimum. I have a 1000 watt PSU that way I have headroom.

Always have headroom

My bad. Reading comprehension problem.

^ And don't forget PSUs aren't 100% efficient. So a 1000watt PSU @ 80% efficiency is 800watts...or at least I think that's how it goes...

No. A good quality PSU should be able to produce at least the full amount for which it is rated. The efficiency of a PSU (which is different depending on the percent load) determines how much AC power is required to produce the necessary DC power for the PC. For example, if a computer requires 1000W of power and the PSU is 80% efficient then it will require 1250W from the wall (1250 x 0.80 = 1000).

1 single is overkill...

Because you do not have the money to buy a GTX295 that do not means that is overkill.

 

[rescawen]

another one of those SPOILED BRATZ

1: most people will agree that at 24 inch a 4870x2 is already very good.

2: 30-40 fps is very fluent game play, so people like you must be so much more no lifes and nerdies then the normal nolife/nerds to buy GTX 295 which still is a overkill.

let me answer your question NO I DON'T HAVE THE MONEY AND IT'S STILL A OVERKILL AND YOU CAN'T DENY IT.

good cards include GTX 260 and 4870

 

[L1qu1d]

no it isn't. A game like stalker and Crysis (Cryostass) All seem to struggle with even a 285 GTX, and also 2 285 GTXs as resolutions.

Don't start knocking people, how do you know they are spoiled? What if they have jobs? They work hard for their earnings. how about you get a job yourself and you'll be able to afford it too.

Don't start bringing ppl down just because they can. I mean if you have factual reasoining, but ur saying that 30-40 is fluent......NO.

LCDs need 60 fps to be fully playable, especially in high paced games, and shooters. 30 fps doesn't cut it. Although the human eye I beleive can't tell at anything 26 (30 fps to be safe) fps, when it comes to gaming, 30 fps is considered playable, but NOT FLUENT.

the 295 GTX is 10-15% better than the 4870 X2, so if the 4870 X2 isn't overkill neither is the 295 GTX.

I call troll on this guy BTW it looks like overkill is your only argument, yet you don't know where Fluent gameplay sits.

Frames per second Gameplay
<30 FPS very limited gameplay
30-40 FPS average yet very playable
40-60 FPS good gameplay
>60 FPS best possible gameplay

Straight from GURU3D.com, care to argue that 2? HAHAHAA

See whens its fully blue, its fluent and the more it starts to fade to red, its not

Enjoy1
