Well I have a big hope in GTX 580 ;

- Higher TMU and ROP numbers, even if stay with 480SP is okay for me
- NO ECC
- NO Dual Precission
- NO Bigger L2 Cache

Nvidia in the last 3 years is very very focus on GPGPU and Parallel Computing, it's time to back for pc gaming. They should make DUAL architecture now, first for gpgpu and paralell computing and the second for gaming, i know it will make the cost of research will be higher but Nv must do this because in gaming is very different segment and almost gamers never touch CUDA and Paralell Computing.
