Yeah, as far as I can see in the article you posted, the OCed 7900GS beats the 1950PRO at 1280x1024 resolutions.
Not in the review I provided. The 7900GS OC still only wins a couple games at that setting. You will see in other reviews the 7900GS will probably take 12x10 with no FSAA (Ananvtech's favorite benchmark settings). But turning on the eye candy the X1900GT will pull ahead.
The article does mention it cannot support HDR and FSAA at the same time, but I'm guessing it can support HDR with normal AA...
All depends on the method of HDR used. In HL2 episode 1, then the 7900GS can do both. But in Oblivion and Farcry, then you need to go to the GF8800's to get an NV card that can do that. If you run HDR in those games, FSAA must be OFF altogether...so if the jaggies bother you..... Might be a small factor for many people. I myself play Oblivion with 4xaa and HDR, something you can't do on a GF7. Matter of fact, I had a eVGA 7800GT CO (oc'ed)and when I got hooked on Oblivion, I just hated the lousy performance and having to decide between 10x7 no fsaa or 10x7 no HDR. With the X1800XT, I could use both at once, up the details and still had better performance outdoors (where it counts).
I'll be using it for BF2 and CSS, so I'll probably end up lowering its clock speeds to get a stable card (cooler too) while still having 60FPS at 1280 x 1024.
Ah, either card will kick butt at those two games at 12x10 resolution. But the X1900GT will perform higher in BF2, especially if you were to up the res. The better IQ will come from the X1900GT as you can run HQAF which looks great in BF2.
In the future, I'll bring its clock speeds back to default for the next-gen games.
I'm not understanding buying an OC'ed card and down clocking it. I'd buy a cheaper reference clocked 7900GS and later OC it if you need to. I bought a PNY 7900GS for $150 no rebates at bestbuy a few weeks back. Anyway, speaking of future, the extra shader power of the X1900GT may just help that card stretch it's lead down the road. Look at Oblivion. Shoot, look at NFS:Carbon where the extra shader power helps the X1950 pro that is often behind the X1800XT, actually pummle the X1800XT.

Besides, I'm an nVidia fan...
And to you that may be worth something and will probably sway you more than any proof I can provide that the X1900GT is really the better card( by a small amount) in most games. You should be happy with either one as long as you don't want to run HDR and FSAA at once in games like Oblivion and don't mind turning off NV's optimizations if their texture shimmering annoys you. In the end both are good cards, I just think the X1900GT is a both a bit better and a bit cheaper.
