System requirements for AO4

[yankeesfan]

I just bought a Pioneer A04 at a local computer show for $300 (US). I now need to upgrade my PC to meet the system requirements. On the box it requires 800 mhz Pentium 3 minimum and recomends 1 ghz. Also need minimum 128 MB of RAM. I would like to know what specifications are best for backing up my PS2 games and is there anything else I might want to know before getting my A04 going. One more thing, I thought this drive was able to burn DVD-R/RW AND DVD+R/RW. I noticed on the box it only mentions DVD-R/RW. I guess I was wrong. Thanks in advance.
