What options would you recommend with

E8400 - this is overclocked to 3.4gHz
8Gb DDR2
Motherboard Gigabyte P45 DS3
Graphics MSI NVidia 9500 GT (can swap with a 8500 GT if needed from another machine)
SATA AHCI 3xHD (2x750Gb and 1x160Gb)
1xSATA DVD drive 1xIDE DVD drive (can change to SATA if needed)

Should I remove unsupported cards - VStream video capture card?

Tried iDeneb and iAtkos on the above without success but got Leo4All to work on the AMD machine my children use.

Also which method is best for dual boot with Vista 64bit?

Thanks
