Looking for an Upgrade to my System

You have a great system. You would gain nothing. Why not wait a few years for new hardware that will come. If I would change anything I would move from ATA optical drives to sata drives. Newer motherboards will not have ata connections anymore.

I believe I have Serial-ATA drives. They don't have Ide ribbon cable or the Molex Power cable slots on it. But I'm not completely sure if that's what you meant.
And thanks, i think i will wait a few years before thinking about a new piece then.
