As long as your MB can do SATA (yours does) your system specs are fine for an SSD drive. You'll also have no issues under Windows 7, in fact SSD drives are perfect for 7.<<And plus,also worries me (i don't trust) my <<old>> system,especially my motherboard ga-x38-ds4.>>
Please view my Specs.
Any idea for that?
You have nothing to worry about
