Nothings really wrong with the 7900GTX, the X1900XTX is just a faster card with better IQ.

Alright, Ill go with X1900 XTX and a A8N32-SLi Deluxe then...or maybe M2N32

if you're going the XT, i'd really think about going the A8R32-MVP. it's a great board, reasonably priced, and will allow you to go xfire later if need be (that is unless you plan un dumping the XT and getting 2 nv cards later).

i've read several reviews giving it high marks, incl. this AT review.

Alright well my only problem is I really want to play UT2007 and its always made for Nvidia. So does this mean X1900 XTX or later Crossfire will be unplayable? Should I just get a 7900GTX?

Dont worry about which game is made for whose card. The worst that could happen is that it will run faster on the 7900gtx or have some extra features, but there have also been a number of Nvidia sponsored games that actually run better on Ati cards.

what makes you think it will play better on nvidia?

if you go by history, ut2004 ran better on ati both 9800/x800/x850 generations. not sure how it runs on current gen, but it's an old game so not incl. in many benchmarks these days....

there is absolutely no way to know now how it will run on current or future hardware.

What? ATi cards have run UT faster than NV cards for years.

 

[EffeX]

This might sound noob, but at the beginning its like Nvidia the way its meant to be played

 

[Praxis1452]

oblivion is like that if I'm not mistaken... and nvidia gets pwned in that

Dont let the logo in the front of a game any thought. Both ATi and NV do this, and it doesnt mean it will play better on one card or the other. As mentioned, Oblivion has the NV TWIMPTB logo, and yet it gets stomped by ATi cards in the game. Performance wise, and IQ wise. Tomb Raider: Legend is the same way, performs better on ATi cards, even though the devs suggest a NV card when installing the game.

Alright thanks man, Ive always wondered about this. Can you tell me if the cable less crossfire will be available for the X1900 XTX soon? I heard catalyst 6.5 would do this.

 

[Praxis1452]

It think it'd be cableless for the X1800XT doubt they'd let X1900XT go without a master card.

If i was going dual setup, i would go for the 7900GTX Sli, single card i would go X1900XTX.

Nforce5 mobos coming in july, conroe/AM2 about same time.

you know there are cheap high quality sli mobos. eg my DFI infinity sli. cost only 125 buck no rebate or any other thing. stable as hell, OC very well (when i do) and is sli.

while i don't recommend going SLI its usefull to have a board with 2 PCI-E slots and 2 PCI-Ex1 slots (incase the ppu comes in pci-E or the ati/nvidia graphic card for physics solutions pan out)

The 7900 GTX is basicly a 7800 GTX overclocked nothing new was added. The 1900XTX on the other hand offers alot of new features and is alot more future proof than the 7900 GTX...

I thought that since they just shrunk the die and upped the core and memory clocks.

They did increase the clocks. But as far as features go, nothing was changed or added.

Alright well im goin ATi this time around.

ati also added more shader processing (at the expense of texture processing). the only "feature" difference between 1800 and 1900 is they added "fetch4" to 1900, however at this point in time it's nothing more than a "checkbox" feature and offers no tangible benefits as there are no games with takes advantage of this.

£259.95 for 7900 or X1900XT? Wow, that's still *crazy* expensive... my Diamond X1900XT was $400 at Newegg (and only $30 MiR)...

Khm: X1900 has 3x the shader power (# of PS ALUs) of X1800 - that should be enough alone for everybody to buy i over the X1800...

 

[EffeX]

One last question is the A8N32 with the X1900 more powerful than with the A8R?

 

[Ackmed]

No, they should be pretty much the exact same speed. I like the A8R32 better than the A8N32, but they are both great boards.

3x the shader pwr but only 5-10% performance increase.... it's not that big of a deal, really... especially if you're on a budget and are looking for best "bang for the buck" rather than simply framerate. not everyone feels $200 is worth a few extra fps.

some would even say ati doesn't quite have the ratio of tex/shader ops quite nailed down yet.

 

[EffeX]

Meh, I have 500$ set aside fro a gfx card. If im going to buy one I want the very best. It seems that the X1900 XTX is performing much better than the 7900GTX.

Yup, but it'll also be a lot louder

I'd suggest getting the X1900XT + your aftermarket cooler of choice & then OCing if you find the performance of the XT isn't enough.

Then you'll have quiet, cooler, & powerful

What is that "only 5-10% performance?" It doesn't make any sense - what game you're talking about?

PS: perhaps you're playing at 1024? In 1600x1200/1920x1200 in heavy games like FEAR, BF2, Q4 etc the difference is more like 20-25% - or playable vs non-playable framerates.

Anandtech found the performance difference between the X1800XT and X1900XTX to be a little more than 5-10%...
