I know the 4870X2 does well cause GDD5 has huge badwith, so im kinda unsure as to the 4850x2
The 1 GB framebuffer /GPU can be seen as a little measure to make up for any performance loss that may have been caused due to sharing the PCI-E x16 bus bandwidth. PCI-E x8 2.0 does affect a HD 4850's performance (source)
. So it's just a little measure, GDDR3 prices are at a low, and 2 GB 'sounds' appealing.
