x1950xtx - x1900xtx

[altine]

i'm gonna set my rig up to a crossfire system....
my first plan was to buy x1950 cross fire and x1950xtx, but the release of those cards were delayed until 14 sept, and the problem is I can't wait for that long ;).

i have other plan:

1. buy the 1900 xtx, and then buy the x1950 crossfire after released.

or

2. buy the x1900 xtx, and the x1900xtx crossfire now.

or

3. wait for x1950xtx and x1950xtx crossfire (like my first plan)


so what would you guys prefer?
please give me some opinion

thanks guys..

September 14th is around 10 days away. Just wait ;)

Yeah....................or 20 since its only Aug 25th

[Celcius]

Waiting for X1950XTX's would be best, but since you can't wait that long, I think you'll be pleased with X1900XTX crossfire performance.

[Rattle]

they are out on the 14th?

[Hicks]

Supposed to be yes.

1) Can you crossfire an X1900 and an X1950?

2) Those will be even cheaper when the X1950 hits.

3) Stick with #3.

Yes

[smith_6079]

Really? Wouldn't that be a bad thing to do? I mean if you were to try and attempt that with an Nvidia setup, it'd be like putting a 7900GT and a 7900GTX together. Has anyone tried it?

With CF you can connect different cards.
With SLI you cant. Or you need to underclock your card.

[ante_ante]

Go for X1950XTX

[smith_6079]

Can't you use one of your cards for physics processing with CF?

I think this option will be enabled on X1950 series.

1) Can you crossfire an X1900 and an X1950?

Yes

You cannot do this for crossfire

how can you run crossfire when X1900 card has gddr3 &
X1950 has gddr4 ? ;)

*From DH: The good news for people who own an X1900 Crossfire Master card is that it is possible to add a X1950XTX to the system and Crossfire works. In fact crossfire works much better than expected with the X1950/X1900 mixture. We had expected scores from the mixed card CF to be almost the exact same as true X1900 crossfire however the mixed card system provided some excellent increases, especially in Oblivion.

Clearly Driver Heaven got it working, and it was faster than X1900 xfire

Where :confused: ...in that article CCC does not even show Crossfire mode
to be enabled.

Show me some 3D marks with X1950 working with X1900 and
then I will believe. :)

CF is defffintly a totally diffrent monster than SLI, SLI needs equal cards (or equal running specs on each card) and scales pretty well as its a total division of work between the cards.

CF seems to be more "additive" letting each card do the work it can and its not equal division, so the faster card will get to do more work and thus you can have a stronger/weaker card setup and not just be downclocking the better card to match the weaker one.

I have not looked at any CF vs SLI reviews of the late but last I checked SLI still scaled better tho and beat CF is most cases.

[cadaveca]

SLi must use the smae GPU between the cards due to the "compositing" happens within the gpu, whereas in Crossfire, the compositing engine is itself seperate, and therefore can accept input from any device.

In reality, you could crossfire x1300 and x1900, although the sync between the frames would be a cpu nightmare!

you can mix both ways and x-fire will work

1950XTX I thought it defeat 7950X2 but ....

[古強者死神]

Its give and take, on some games the 7950GX2 will win on others the 1950XTX will win, they are built diffrently and both have diffrent strengths.

I say they are equal for the most part. I have not used an ATI card in a long time so getting used to there drivers is a big issue for me and there software however I will have to say as a Nvidia fan I consider the 1950XTX to be the winner if it does retail for 400$ as the 7950GX2 is currently 500$ the cheapest I can find.

For the small performance diffrence 100$ diffrence easily justifies wich ever way one card may beat the other in a certian aplication.

I need to find the exact figures on the heat/energy figures tho.

if the 1950xtx takes up massive energy and turns my room into a sona, I may still go with the 7950GX2 as my personal card of choice.

In reality I think I will set both out tho and wait for next gen card to come around.

[Hicks]

Crossfire smashes SLI, when massive amounts of AA/AF are used. Which is what you want to use, when your comparing 7950, and X1950.

[Caubecari]

On the other reviews it show that 1950 win with the speed for the core clock is 650Mhz and Memory clock is 2000Mhz. Why this review only show that X1950XT only 500Mhz for core clock and 600 for memory clock

[EsaT]

(>550EUR)

Mixing cores is for wh0res

Combo #3

[perkam]

I've tried to tell this to people many times to avoid having issues later.

Firstly, a single X1950XTX will give you all the power you need to run any game at the higest settings with maxxed aa/af and high fps.

Secondly, spending $1000 on a setup without understanding its mechanics will only lead to dissatisfaction. all X1900 series require knowing which programs to use and how to use them...in order to enable volt adjustments to reach higher OCs. As of the moment, there isn't even a software out there that can clock the ram beyond 1143Mhz...even if the memory was capable of 1250 (2500 Effective) and even if you gave it 3.0v, it wouldn't go higher cos of software limitation.

So buy one for now, figure it out...get the higest oc you can by tweaking the heck out of it and then, if you need the second one for crossfire, buy the one that ppl say OCs best.

If you jump the gun, you'll just be waiting there with performance little different than two $300 7950GTs.

I'd say, buy one card only.

Buy an X1900 XTX, ( you can have it for $280 after a $150 MIR @ newegg.com)

It's already september and spending a lot of money on cards that are DX9 based when Vista and DX10 cards are just around the corner makes no sense to me. But then again, it's your money:stick:
