uhhh ohhh bad news.
nVIDIA PCI Express
Doubles the bandwidth of AGP 8X, delivering 4GB/s of upstream data transfer and 4 GB/s of downstream data transfer.
from the ecs website. however, just because the name of the slot is x16 doesnt mean it runs at 16x.. lemme do a little research.
EDIT:
from www.amd.com :
A PCIE link with only one lane is an x1 link – add another lane, it becomes an x2 link, and so on. Each lane is bidirectional, can send and receive data simultaneously, and can provide 250MBps of bandwidth in both directions.
wouldnt that mean that an 8x link width ultimately = x16??.. and therefore wouldnt like an x4 link show up as two lanes in windows??
wow.. that seems to work like hypertransport. i mean, it makes perfect sense doesnt it?
