Get the X1900 XT/X, it has the best image quality by far, overall edge in D3D performance, offers HDR+AA and has software voltage control
+ overclocking. Here's a review that was released today:http://www.bit-tech.net/hardware/200...roundup/9.html
Although the screenshots show differences in image quality, one has to keep in mind that shimmering/texture crawling are not nearly as visible in shots as they would be in motion. In another words the effects of nVidia's AF shimmering/texture crawling is much more pronounced in motion compared to still shots.
Here are some interesting snips from their review:
|The GeForce 7900 GTX trades blows with the Radeon X1900XTX in our selection of popular titles, but doesn't deliver a knock out blow. In that respect, neither does ATI. NVIDIA has succeeded on a number of fronts, but we feel that they've missed out on at least one important feature in their move to 90 nanometres at the high end.
We feel that NVIDIA's hardware suffers from having lower realistically playable image quality - high quality anisotropic filtering is a given on the Radeon X1900-series cards, meaning that they are in a different league on the image quality front. If you're looking for the best-looking pixels in the business, you should be using an ATI Radeon X1900XT or Radeon X1900XTX.
From their BF 2 benchmark:
|The Radeon X1900XTX was able to play the game at the same resolution as the two GeForce 7900 GTX frequencies that we've tested here. We found that Battlefield 2 was playable at 1920x1200 4xQAAA 8xHQ AF with all details set to their maximum. High quality anisotropic filtering made a huge difference in this title. Even with high quality driver settings, there were still some quite large differences in texture filtering quality - this was most noticeable on gravel or grass-textured areas.
From their AOE3 benchmark:
|Of course, the Radeon X1900XT and Radeon X1900XTX both support HDR and antialiasing, meaning that we were able to apply antialiasing without much of a performance hit. We were able to play the game at 1920x1200 with 2xAA 16xHQ AF and maximum in-game details, including HDR bloom. The Radeon X1900XTX was able to maintain a smooth frame rate with performance adaptive antialiasing applied too. Sapphire's X1900XTX gave a relatively unparalleled gaming experience in Age of Empires III in all honesty - the image quality was damn good.
Let's see, you can get X1900 XT/XTX CHEAPER in the UK right now from OC UK and USA (see sig) than a 7900 GTX, availability is higher everywhere and you won't get the eye poking needle AF with ATi cards. Seems like a slam dunk win for ATi.
