After I dropped my waterblock on my Ti200 GF3 and sent it to electronic heaven, I decided to buy another NVIDIA card (choice was hard though). I picked the Gainward Ti4800SE as I could get it for $158 with shipping from googlegear and the card has VIVO (which is just an added bonus for me).
Anyway with stock heatsink and ramsinks, its running stable at 331/661 and I just haven't tested any settings between this and 345/695 (highest Rivatuner setting before warning) and it failed here.
