Yeah, I plan on building an i7 machine in February, waiting for prices to drop, Uncle Sam to pay up, and bugs to be worked out. If Nvidia can refine their GPUs with 55nm process and get the performance above ATI, I willl be probably be switching back to Nvidia.
Currently Im running 2 4850s Xfired, and I cannot complain one bit. I try to keep an open mind but Nvidias constant be-badging of old products, and my mediocre experience with my Striker Extreme (680i) its going to take some convincing numbers for me to switch back to the green team.
