Here is some information on ATI's new cards. Benchmarks reveal they are twice as fast as the GEForce 285! And the GEForce 285 is much faster than the hardware I originally designed the engine for, the GEForce 8 series. I need to get my hands on this stuff so I can see where the bottlenecks are. I don't have to require an ATI 5870, but it would be a good idea to design things around that so that the engine scales with the hardware and can do more.

NVidia seems to be focusing on computational stuff. I'm really not sure how I feel about buying a GPU that's designed to run C++ code. I am sure there are some competing variables that would cause a tradeoff when you are designing hardware for graphics versus general computation. I like NVidia hardware, but are they losing focus?
