i just found out from asus website my asus a8v deluxe doesnt support SATA 2 harddrivess. and i need to buy a second hd, so it has to be ata, am i missing much. is the ATA terrible compared to SATA 2 for playing games. right now i only have two choises SATA (not SATA 2) and ATA. is there a noticble difference between them.
