5900 NU price dropping like a STONE in DEEP water!?

Wrong again Nebor. I could go into detail, but its not worth it ... u have to figure in the factors whether the stone was in motion before it hit the water, or was it static ... well, utilmately, it'll reach terminal velocity (uniform speed) at which it'll be sinking

No, he actually is right (assuming you're talking about dropping from rest at both points). Ie, a stone going from rest to dropping from just below the water's surface will have the same speed as one dropped from 100 feet below.

Of course if this is the same stone we're talking about then obviously it will be faster at the lower point due to acceleration as long as terminal velocity has not yet been reached in the first case.

But he is right, the stone drops at the same rate (ie acceleration) no matter where it is in the water. And in this sense he is right about deep water making no difference - the depth of the water does not matter on the stone's rate of descent.

Nebor is right if you disregard turbulence and resistance from the water.

Um, the proposition was that--all but the water depth being equal--a stone would fall as fast in deep as in shallow water. The only variable is the depth of the water, and the deeper the water, the greater the pressure, thus the greater the potential resistance to gravity's sweet, sweet pull. Why would you disregard the water? That's like saying simply that a stone would fall, without qualifiers. Uh duy. ;P It's not interesting without at least one variable, and that's the water. Sure, the difference in pressure/resistance between just under the surface and 100ft. is probably minimal, but my conception of "DEEP" water is a little more than 100ft. Maybe I've been seeing too many ads for salvaging wrecks and giant squids from the bottom of the ocean.

Thread is about the prices, give it up with the whole physics of stones falling in water, it doesn't really matter, the fact is with deep water, it will drop down alot more, if its shallow water, it will cap off somewhere soon

I gotta say...the price of the 5900 NU seems to be dropping every day by a buck or 2 over the last couple of weeks. Seems like every day there is a "new" low price leader at Pricewatch on the XFX 5900 NU. It's now down to $188.00 with no rebates and including shipping!

It also seems like the better pricing on the 5900 NU is starting to put some downward pricing pressure on the 9800 NP (and maybe the 9800 Pro). The 9800 Pro seems like it rarely dropped below $300.00 and now there are a few e-tailers with the 9800 Pro at $290.00.

It about time the higher end cards to trended lower in price...$300+ for video cards that have been out for 6 months or more is pretty steep in my opinion.

still not that low, i got mine 177 AFR including shipping, so until it's below 170 or so mark it really isn't that amazing, considering i got mine like 4 weeks ago or so

im surprised it took someone this long to understand. the difference btwn deep and shallow water in reference to the post title, had nothing to do with the speed of descent, but the fact that in deep water, the stone would KEEP falling low low low... like the prices?

Well, provided that you're getting a card with the 2.2ns memory, it really is well worth the investment. Here's the overclock I got, right out of the box (after installing the 53.03 eVGA Drivers, and using the Coolbits registry key, as provided on the XFX Setup CD): XFX GFFX 5900 Overclock The cooler on the card is not the massive reference cooling device used by most manufacturers, it's an Aluminum heatsink/fan that works and isn't too loud either. Also, to make things easier on your ears, set the 2D Clock to 200MHz or so and that way the 'noise' will only kick in when you play games.

Peace

I havn't overclocked my card yet, i mgiht try it around HL2 release, i don't wanna have it working to hard, i would like to keep it for at least a year and 1/2, i can always upgrade processor and ram when it drops down, since my Mobo can handle a 3200+, and prolly the next 32-bit processors that AMD has coming.

I've set my 5900 core to 75MHz in 2D and it's still snappier than my old Ti4600.

 

[Blackroot]

how do you set the core different for 2d, maybe i can do that to cut down noise, my comp sounds like a vacum

Google for "Coolbits registry hack." It enables an overclocking tab in the Nvidia control panel. Remember the memory runs at the same speed in 2D and 3D modes, only the core changes.

Blackroot....glad you pointed out the "point" to my thread! I didn't have the heart to tell those guys

 

[yhelothar]

2.8 ram isn't that bad. there are benchmarks that show that geforcefx doesn't benefit much from the extra memory bandwidth. Mostly the core that affects the performance. So your choice if you decide to save $20 or so for 2% less performance.

Links?

 

[DaveSimmons]

For 2.2ns memory plus video-IN not just -out, newegg has the $229 Gainward fx5900 card (second of 2 listed at that price, stock speed 400 core / 850 memory).

 

[Pete]

Link. The only time the 5900V falls behind noticably is with only 4xAA; otherwise, it's about even in plain rendering or with AA+AF.

 

[pillowboy]

Link I just ordered mine from here last nite, it will arrive on monday, i will see what version i will get (cross fingers)

 

[gryfon]

pillowboy, please post here once you've received the card. I also bought one today, sadly i didn't came here first and see this topic , if the card you get isn't ver 2.2 than that should make me better somehow... still want the card badly though... Does anyone here has the ver 2.2 of the card ? is it "usable" if i slow down the mem to 700 ? Or it just wasn't worth for the money ? I'm a newbie here

Thanx guys, cheers

The whole arguement was starting to piss me off, i decided to just tell them, lol

But you are not considering the property changes of water as the depth increases. Temp is going to lower causing the density to increasity. This will directly affect the rock's rate of acceleration in several ways. Good god, do I want to go into fluid dynamics at 3+am in the morning????

 

[pillowboy]

just received my xfx5900 today, Its not the V2.2, its version 1, default speed at 400/850.

 

[jsp0000]

My postscript:

I ordered the xfx5900 from newegg and received it yesterday. It was the revision 2.2 card (700Mhz memory). I wasn't happy about it and asked NewEgg for a refund.

NewEgg is a terrific company. They refunded my full purchase price for the XFX 5900 and paid the return shipping. They have an Albatron 5900PV for $199, ten more than I paid for the XFX. It has the full 850Mhz memory and VIVO. I went for it. We'll see if I have buyers remorse with *that* manufaturer

XFX and NewEgg have corrected the specs now, so hopefully no one else will end up getting something other than what they thought they were ordering.

 

[pillowboy]

i actually didnt order mine from newegg, i missed out on it then i ordered from another online place which i had link above. it seems to work fine so far, been playin ff11 on it for a while everything is running smoothly

 

[Rogodin2]

I can't hold off on the deal and have ordered 10 of the 5900NUs for customers. Catagorical imperitive doesn't have a logical fallacy as the premise with the apprehension of the 5900NU for less than $200.
