Trying to piece together a new computer and have some questions. This will be a semi-budget gaming rig but I'd like to be able to run bf2 well on pretty high settings. That's my main goal. Got some questions though... How do I see how powerfull of a PSU I need? I have a 430w Enermax. Not sure I'd be able to reuse but I'd like to if I can. SATA-II or SATA-I? I see SATA you can get 10k rpm drives but the data transfer rate on SATA-II is a lot quicker. Please help clear the differences up. I've search online and can't really find anything on the two. Doesn't appear SATA-II is really more expensive either. How do I tell if I need unbuffered or buffered memory? What about ECC and Voltage for memory?
