Anyone using one of these yet ?

Would be interested in hearing some info on this cards performance.

This must be extremely new. At first I thought you meant the Geforce 6800 (which I`ve only just ordered). But checking around I do see there`s a 7800...

It must be really expensive. No idea what it`s like.

I just replaced my 5200 with a 6800GT (I never get sick of saying that) http://forums.ubi.com/images/smilies/16x16_smiley-very-happy.gif.

I'm very happy with it. I probably won't be looking at getting another until BoB comes out.

from THG site:
blades of grass or chain-link fences are rendered more sharply by applying a technique similar to the way ClearType makes anti-aliased text look sharper against a multi-color backdrop

Wonder if that makes planes easier to spot.

mmmm sounds like something that will run water 3. I bet it still won't be enough to play BoB on full settings when it comes out.

edit: sadly no IL2 benchmarks.
Which site usualy uses IL2 to bench?

7800GTX (http://www.pcworld.com/resource/article/0,aid,121548,pg,1,RSS,RSS,00.asp)


The 7800 chip has 8 vertex shader pipelines and 24 pixel shader pipes, whereas the chip in 6800 Ultra boards contains 6 vertex pipes and 16 pixel pipes. The extra pipelines account for much of the new chip's high transistor count.
, but even more interesting is
At the same time, NVidia's engineers analyzed how those pipelines work and optimized them to run typical game code faster than before. The result, NVidia says, is that the 7800 GTX can outrun the 6800 Ultra pipe-for-pipe. .

If I went for it, I would want the sooner or later 512 card, not 256. With an actual new and advanced GPU, 24 pipelines and each of those pipelines being faster than the ones in the 6800u, you may not actually push to using 512, but you probably will be able to push beyond 256. If I started off running two of those in SLI, it wouldn't be a problem, but I doubt I would buy 7800GTX x2, plus a PCIx mobo at the same time. The comparisons they used in that link was using only one 7800GTx and it already beats every other card (according to them) and SLI sounds nice, but in reality, hasn't been much for performance increase, never mind best bang for the buck since it's not much of a bang and a heck of alot of bucks.

nvidia says the card should be in the market..today. I looked around, haven't found anyone selling yet. Nvidia wants it to sell ay $599 or so, about as much as the PCIx 6800u. I am sure this price will be marked up past what nvidia wants. I got my 6800u first month it came out. I paid well over the list price nvidia was qouting for it then.

I am not really hurting for a new video card at the moment and although the 7800GTx already shows that it out performs everything, its not that big of a difference.

The card I am interested in seeing is ATI crossfire cards. Hopefully it'll be comparable in performance to the 7800GTx, plus it runs 6 monitors......I haven't seen specs on the 7800GTx, but I don't think it supports that.

I don't get the need for 512mb cards, the resolution is hardly going to be pushed over 1600*1200, with full AA/AF you should have no problems with 256mb.

You can buy the 7800gtx for 100 less than 6800U 512MB. Most monitors that can manage 1600*1200 do so at 75Hz or less which I personaly can't watch for long. So I suspect many people will be running at 1280 for comfort.

I know you can cache more textures with 512mb cards but with the *16 PCI-e interface you should notice little differece from a 256mb card.

Now running 6 monitors, Now that would take a chunk of memory for sure.

In the firingsquad preview, PF looks very CPU limited, or is that a product of using an ntrk?

HardOCP has a great in depth preview (as do many others) ...
http://www.hardocp.com/article.html?art=Nzg0LDE=

Great looking card. Dang things VERY fast ... and screams at 1600x1200 with 4AA & 4AF ... some other nice goodies too.

It's going to be a good summer ... ATI's X900's come out in a month ... 32 pipes! http://forums.ubi.com/groupee_common/emoticons/icon_biggrin.gif

We can't lose! Having both companies compete like this is always very good for us flightsimers and gamers in general.

One thing I can't figure out about the new 7800 ... why don't they vent out the back of the case like the X850XT PE's do? The 7800GTX's are hitting 80C ... thats a lot of heat going into your case?

new equipment at BoB release (2007?) will blow this stuff away...pick up 7800Ultra on the day 1c releases BoB for $150.00 tops along w/new mobo and still get change back from the clerk.

Apparently this card is as fast or faster than 2 SLI 6800 Ultras in the Battlefield 2 demo. It also draws less power than a single 6800 Ultra.

But I'm not spending $600 for a video card.

I'll probably replace my 9800 Pro with one of these... in early 2007.

Its not worth upgrading to a 7800 from a 6800 as there is little or no frame rate increase in FB. I would wait for two years for BOB's release and upgrade then if you already have a system that runs FB well.

there is a great need for more memory on cards - sure as the end user you can crank 1600x1200 and not get too much texture thrashing, but thats because the developers had to go through the pain and heartache of removing resources and reducing texture quality to make it fit on modern cards. Havent you noticed that the Doom3 texture and bump map quality leaves more to be desired - and on ultra quality that fills almost 750 megs of texture memory.

Whats the point of so many pipelines to simply run current gen games better? Next gen games are going to require 512 for optimal quality i expect.

I will wait for the mid end version of this card to replace my 6600 GT. This G70 has twice the capability of MADD operations per clock per pipeline.

A pitty that a 7800 here in Brazil costs as much as a full month payment from a Importatn University Professor or twice my month payment as Game developer.

Yes the big problem is with BoB looming in the background hardware choices are going to have to have careful consideration ( at these prices anyway ).

The Firing Squad review was interesting but i take it no one heres got one up n running then?

I was interested to see how it handled water 3 animations.

due to SLI you need the small footprint of a single slot solution for proper cooling IMO. 2 Ultras drops alot of heat

The frame rate increase shown are kind of misleading as the 7800 is running 4 X's AA and the 6800 is running 2X's.

Now I'm no NV fanboi obviously but it is a nice card. A decent improvement in higher resolutions,AA,Supersampling AA, and with water 3. 24 pipes is a good improvement...let's see how it performs on a dual core system soon before passing judement in IL2. Reason being is when the CPU can handle more of the load PF performance will increase. Also 512 of memory would be a bigger help also as proven with a X800XL with 512 in Doom3 beating 2 6800 Ultras in SLI.

Well in still getting by with the Gf4 ti 4600 on a 3 year old system XP 2600 1.5 gb ram Abit KR7A Raid mobo etc etc

3d guru have a good article on this new card, and Tomshardware review seemed to balance the hype so to say.

Its just if you react to all the new hardware coming out immediately you dont see a big difference within a short time scale.
I know for fact that my upgrade from Gf4 ti 4600 to 7800GTX will be a massive improvement but not worth installing in my current setup as I probally have too many bottle necks in the system to get it to run as it should, if at all.
So for me its not just a card upgrade im looking at but a system upgrade, I was hoping for some specs on card and system if anyone had one running.

Now wheres that piggy bank gone to ??
