SATA vs. SATAII

[Slime101]

My HDD's are Sata drives, 80Gb Boot/progs and a 200Gb Data drive (both 8mb cache) - as i'm upgrading from my celeron system to a C2D system would i actually notice a difference if i was to swap over to SATAII drives?

So double would be really noticable then...hmm

I shant bother rushing out to replace them then

Thanks for the input chaps.
