Awesome review :)

I've said it once but I'll say it countless times, the reviews on bit-tech.net are always amazing and in the past month have been tailor made to my needs as I've chosen a new computer! The initial GeForce 7950GX2 review highlighted the essential point that one of these would be as fast as a pair of 7900GTs in SLi which was the biggest question in my mind at the time, and the review of the Dell 2407 WFP reassured my purchase which is on its way right now :) I love you guys!!!!

That's impressively fast - I thought it was more of a gimmick than anything, but it's turning out to be quite a nice piece of kit. Good review; I like the clickable pics too :)

Great review and great idea to put them all in one... time to read and grab a calculator and see how in h*** ill aford one of those beauties...

The review surprised me quite a bit to be honest. I expected more performance, considering the fact that it's two cards bolted together, and the cost. Were I buying a high end card I'd probably go for the 1900XT or XTX due to the higher image quality, HDR+AA, and cost.

Great review though. I loved the fact that it was split into a bit for those of us with CRT's and then for those weirdo's who use silly cold LCD's to get their kicks. That was great.

Awesome write-up!

I still think the 7950GX2 is an excellent value since alot of them are $100 (don't know how much that translates in Euros) more than a 7900GTX. If decide to go high-end, then this is the card for me .

with the only gameplay advantage that the XFX 570M XXX Edition card having being the additional quality benefits from enabling transparency supersampling.
Why isnt listed under "benifits" then ...., and why does another card have a benifit, which isnt mentioned

Who would have thought that you would be able to play Half-Life 2: Episode One at 1600x1200 with 8xAA enabled? Both GeForce 7950 GX2 speed grades were playable with 8xAA enabled
I also dont understand this, i thought the GX2 was more powerful then the x1900xt, and yet i could play with everything on max (inc reflect all) and not forgetting 8xAA and 16xAF and at the lowest only ever saw 50fps, and generally floating at about the 70fps range getting up to over 100 at some points

Uhh, ohh... for some reason, the table on page 9 was the wrong one (the 1920x1200 table had crept in there - probably me copying image code) - refresh now and it is corrected. I will have a quick check through now. Thanks for spotting - can't believe I missed that. :o

Brownie points for including a 1920x1200 test ;)

Wonderfully thorough review, i just wish i had the cash...

Great article. Will these cards support directX 10 when suitable drivers become available or will new hardware be required for that?

yes, but have you heard anything about quad SLI drivers for there? I want a pair bad! :D

Well written and very informative as usual Tim ;)

If you get a minute could you let me have the measurement between the two cards i.e. from the bottom of the top card to the top of the bottom card (if that makes sense :|

Cheers

Hi and welcome to the forums.

Unfortunately, they will not support DirectX10. However, there will be very few DX10 games coming out for a while yet - it depends on how long your average video card life cycle is. If you're one that upgrades every six months, I think that it is fair to say that GeForce 7950 GX2 will last out that time.

If you're more of a 12-to-18 month upgrader, you might be better holding on for a while.

There are some SMT components, so I would say that you're looking more like 15mm clearance if you take the GPU being raised from the PCB into account.

If I understand correctly, DirectX10 will emulate (or include), DX9, so most if not all current cards will support DX10 (in the sense that it will work) , although won't take advantage of any new graphical effects DX10 brings. I mean, you won't see any DX10 stuff in, say, Crysis with a 7950 and DX10, but it will work flawlesly if you have a 7950 and Windows Vista. I guess you are probably saying the same, but it read like your shiny new 7950 would't work at all with Vista and DX10.

Or have I misunderstood all this DX10 news?

Absolutely spot on Tim.........greatly appreciated ;)

I'm still waiting on a card to see what goes where.

Thanks again for your time.

Yes, that is the case - you will be able to run a GeForce 7950 GX2 under Windows Vista, but there will be no DirectX 10 'eye candy'. :)

Great review...really informative.

Appart from the fact that there is only one interface with the motherboard, these really are not a single GPU. They are two cards bolted together, kind of cheating really just to get the fastest card.

It would have been good for a point of reference if you also ran an ATI Crossfire setup. That would have given a more realistic performance point since the 7950 is Nvidia's somewhat warped vision on what a single GPU is.

Keep up the good work.

The problem with X1900 CrossFire is that it costs £600-650+, whereas the 7950 GX2 costs £400. ;)

We don't have access to X1800 CrossFire so we can't compare it to that. We tried for months to get an X1800XT in order to review 7900 GT / X1900GT and we don't have the time to waste on sourcing hardware if it isn't readily available. If we can't get it after a week of trying, we tend to just move on because there are so many other things to work on (especially with a 3-month backlogue). :)

i think you have
DX10 will include DX9, like current versions include older versions, DX9 is compatible with DX5 games i believe (i know it supports DX6 games)
But a DX9 card will not support DX10 functions in any way, the same as now, if you have a DX8 card, DX9 functions WILL NOT work on it, but anything before that will

The price vs performance is the things that I'm really interested in because I'm pretty sure that X1900XTX in CF mode will own the 7950 GX2. The interesting thing is by how much and the relative £ per frame.

it cant be easy sourcing all of the hrdware and performing industry leading benchmarking and editorials. Out of interest, you dont have a little scoop on DirectX 10 hardware yet do you? There is an article over at http://www.extremetech.com/article2/0,1697,1982032,00.asp where they picked the brains of Microsofts Chris Donahue. He said that we should expect DirectX 10 hardware within two years :|. Thats all he could give because now its down to the hardware manufacturers. Since you guys have your finger on the pulse...have you heard anything...at all. The community needs to know!

the 7950 GX2 seems to give margianlly (very marginal) over the ATI cards, a x1900XT will set you back £352 (www.overclock.co.uk) whereas a 7950 will set you back £408
For ~£50 more you get like 5% performance gain (maybe) but its a better cooler, and it uses less power (i believe) and its not using the catalist software

But you have the hassle of SLI profiles and such
