anyone who's had both a 7800gt/gtx and x1800/x1900

thank you; appreicate your time, but that's not what i asked.... and i'm also not looking for someone who has formed an opinion by listening to their friends or one website or another, rather someone who has had hands on experience with both (and assuming that's not you by the x800 in your sig). i've had both x800 and nv40 and was happy with the IQ of both.
what i'm interested in now is the new AA modes in the g70 and new AF modes in the r520/580. more specifically, how they compared in "hands on" evaluations over multiple games - something you kind of need to own one to be able to give.

I've had both and I wish I would have taken some screenshots when I had my GTs. I haven't really taken any time to see if I notice any difference (which probably means it's not a huge difference). The thing I am really impressed with is the ability of the ATI card to do HDR+AA. Some people have said that it's an unimportant feature but having played FarCry with the 7800GTX I used to have I can say it is a huge difference. The game looks absolutely gorgeous at 1920x1200 6AA/8AF with HDR enabled and details maxed. It is very playable too in single player mode. Minimum frames sit at ~33-35fps and usually hover in the low 40's in the Training level. I'm amazed that the X1900XT can handle that kind of load but it just chugs right along.
Sorry that doesn't really answer your question about the AA and AF. I'll pay a little closer attention next time I play.

I've only had my 7800GT, no ATI, but I love the quality of it. The Transparency Supersampling AA makes all the difference.
You better keep on driving 😉
Actually with AA they seem to be equal, but ATI has an ever so slightly less drop in performance when it comes to AA (as in you will not notice it most of the time).
With AF ATI seems to have a slight lead, but both are comparable. And performance hit is less with ATI again here but not by that much.
And with HDR+AA, yes it's a nice feature, and it's usefull (and I want it)

Wheres nitromullet. He should know.
I currently have an ATI 1900xtx which replaced my BFG 7800gtx oc (I have owned 2 GTX's). I have noticed a difference in IQ I prefer the ATI, the colors are not as vibrant on the GTX. The HQ AF on the ATI is much better than the AF on the GTX. AA is about the same but I take less of a fps hit with the ATI. I currently have 3 6600gt's for the wife and kids and the 1900xtx for me and I prefer the IQ on the ATI.

Mom: Geforce FX5200
Dad: Geforce 6600GT on Zalman VF-700Cu
Sister: Radeon 9200
Me: Geforce 7800GT on Zalman VF-700Cu LED
I've had a 7800GTX and a X1900XT. ATIs AF is definitely better (and still faster) when HQAF is enabled, and AA is about the same. There is also this to consider, since some people are having the problem: http://www.rage3d.com/board/showthread.php?t=33845168

what about framerate? Im not happy with my 7800 gtx 256mb. How much diff between the x1900xt and 7800 gtx 256mb?

He said newer games and hes right. But I dont know why hes that worried, because playing non native isnt that bad.

My honest and unbiased opinion:
As someone that values AF quality very much, to me HQ AF is quite noticeably better than anything nVidia offers. Even the default AF of the ATi card is noticeably better than nVidia's default quality AF. As for the AA differences, I'd say both are on par with neither looking any better than the other. Performance AAA on the ATi card is better than TRMSAA found on the nVidia card but TRSSAA looks ever so slightly better than Quality AAA if you look very very carefully (most wouldn't see it though).
Another subject often not brought up is shadow quality. IMO from what I've seen so far, shadows are rendered slightly better on nVidia hardware than they are with ATi. This could be due to a driver bug, I'm not sure, but in BF2 (despite it's crappy subpar shadows) the shadows on my GTX looked slightly better than they do with my XTX.

I'm going to talk about this in terms of single cards because my CrossFire experience is minimal...
AF: ATI wins this hands down. Once you know that NV's is angle dependent, you can actually watch it change as you move from side to side (change angles). That being said, neither is bad by any means, but ATI definitely looks better.
AA: Both AAA and transparency (esp super sampling) AA are great. After playing with these features, it's hard to imagine games without them. Overall though, I give the AA win to NV for single cards simply because NV's max AA is 8x and ATI's is 6x, and there is a difference. Again, neither is bad, but I think 8x AA just looks less jagged.
HDR+AA: I don't know, I haven't tried it.
Someone else already mentioned that the colors on their ATI card simply looked better, and I have to say that I agree. The colors are overall deeper and just more pleasant to look at with the ATI card. Personlly, I think this is the main reason that people have been claiming that ATI has better IQ all this time.

techNooB :! you haven't been reading alot :! ATI is faster and has better IQ :! I love you technoob 🙂 /me calls in airstrike at TechNooB anti-flame moble
ATI HAS MUCH MUCH BETTER IQ :!
FLAME ME ALL YOU WANT : )
nah seriously :! i changed from 7800GTX to X1900XT and i am very happy with the peformance and the IQ and I love AVIVO 🙂
if Nvidia 7900GT beats 7800GTX than its pretty awesome card for $299 but if X1800GTO beats a 7800GT and just beats 7800GTX then its much better deal for $249.
I would wait for X1800GTO and 7900GT and 7900GTX to come out because then Nvidia and ATI will go into price war :!
But to your question : ATI HAS MUCH BETTER IQ THAN NVIDIA :!
P.S. Technoob :! you have Corsair ValueSelect 2 x 512GB :? fix it noob 🙂
It may not be "that bad", but I certainly feel that if I buy a new top-end card I should be able to play *any* game maxed out on my screen.
I refuse to buy any card that can't run the UT2007 at 1920x1200 at less than 60fps. I can run non-native now on my X800Pro - why would I buy a new card just to run at non-native resolution again?
