The significant issue that clouds current ATI / Nvidia comparisons is fragment shader precision. Nvidia can work at 12 bit integer, 16 bit float, and 32 bit float. ATI works only at 24 bit float. There isn't actually a mode where they can be exactly compared. DX9 and ARB_fragment_program assume 32 bit float operation, and ATI just converts everything to 24 bit. For just about any given set of operations, the Nvidia card operating at 16 bit float will be faster than the ATI, while the Nvidia operating at 32 bit float will be slower. When DOOM runs the NV30 specific fragment shader, it is faster than the ATI, while if they both run the ARB2 shader, the ATI is faster.
My first computer didn't come with a 3D card. They hadn't been invented yet heh. Several new 3D cards came out. I bought the first ATI 3D card from egghead (when they had stores). It was before the rage pro. ATI had every game under the sun listed on thier web site as being supported by thier card. They were flat out lying. I never played one single game that had 3d support for this card that was not bundled with the card. Tomb Raider was the hot 3D game at the time besides Quake. There was a 3D patch for Tomb Raider for every 3D card out there except ATI. Yet ATI had the nerve to put Tomb raider on thier web site as a supported game. They also had Quake on thier web site as a supported game. I emailed them asking when I would have 3D support for quake. The guy actually told me in his response that Quake was not a 3d game. ATI kept promissing open gl suport. It never happened. Not until a couple more generations of cards came out. I almost forgot to mention the nightmare I had installing this card. My first experience with ATI drivers.I felt totally ripped of by this card. Then ATI had this trade in program where you could send your old card to them and they would give you a dicount on thier new card. But the discount was so small I could get the card cheaper just buying it at the store. What a joke. There was alot of hype over the first radeon card so I bought it as soon as it came out, Again I had a nightmare of a time installing this card. The drivers were buggy. I didn't believe ATI's promisses for the future DVD player software because of my previous experience with them. Luckily I was able to return this card. The Radeon 8500 all in wonder seemed like a bargain so I bought it. Again another mistake. Same problems installing the drivers. All kinds of driver problems. Many hours wasted trying to get it to work right. So you would think by now I've learned my lesson. BUT NO. I bought a radeon 9700 non pro because it seemed like a bargain especially if I could get the soft mod to work. Quess what the soft mod worked but I had artifacts. I tried using the card normally but The drivers were so buggy. My system felt bogged down. I had hard lock ups in win XP. Spent many hours messing around reading how to fix the problems. I finally gave up. I have not tried the new cats 3.4. I don't really want to go through the trouble. I still have this card because I could not return it where I bought it. Anyone want to buy it? The only thing good I can say about ATI is thier image quality is noticably better than Nvidia's. I wish thier cards would work. Nvidia cards always work well. The drivers install with no problems. One time no fuss and your playing games. I don't care if ATI is a little faster I will buy the card that works.

Hump: It means ATI and Nvidia do shit differently in their cards basically. Who'd a thunk it. I wish JC would just come out and tell people to stop relying on this shit benchmark.
