- For $15 more upfront you can get Asus P5Q Pro + Asus HD4850 combo (2nd on this page) and you get a $30 MIR instead of $20. So $5 more AMIR gets you a much nicer mobo.
- You can get Kingston HyperX 2x1GB DDR2 1066 + Antec EA650W combo (2nd on this page) for $9 more. Gets you better RAM and stronger PSU.
If you opt out of the suggested psu/ram combo above, I would get 4 gigs of ram, especially if you are using vista. DDR2 is dirt cheap, you can't go wrong.
