I started using NVIDIA since the gf256 and I stayed with them untill I saw the 4870. I just couldn't find reasons anymore why I wanted to stay with NVIDIA. Now going on to 2x4890. I used to buy simple 6800ultra's at €650 but thank god ATI/AMD came with good cards and NVIDIA's pricing is /fail now.

I don't know in USA but over here NVIDIA is doing 0,0 effort with their upcoming celebration of 10years GeForce brand (31st august). If I were a manafucturer who wasn't in deep sh*t, I'd be throwing competitions all over the world.
Me too. SOOO glad I jumped ship. my last nVidia cards sucked asss

I guess it all comes down to what you want in a card... good benchmarks, or good gameplay

Personally, of the five ATI cards I have owned, all five had texture clipping issues, and improperly drawn shadows. Of the seven GeForce cards I have had, only one had issues and it was due to faulty memory on the card. You are correct, the ATI cards all outperformed their Nvidia counterpart at the time in synthetic benchmarks (which is why I bought them instead of the Nvidia at the time) but when it comes to gameplay, ATI still needs driver work. I have simply been burned with less than stellar video anomalies by too many ATI cards to trust them anymore.
I have found ati drivers brilliant apart from initially having to spend a day to get crossfire working. I found nvidia drivers terribly unoptomised.
