What exactly do you hope to gain using a RAID configuration for gaming? If your motherboard doesn't have some sort of RAID controller, then you'd have to do it via software, and it'd just be extra load on your system dragging down your game performance.
Either you need to learn what RAID really is and does, or you need to better explain what you're hoping to gain.
And as for moderately priced PCI-E cards... No such thing. All PCI-E cards are going to be high end given the high end nature of the PCI-E bus right now.
