I would suggest either the Clevo D900K (aka Sager 9750) or the Clevo M570U (aka Sager 5760).
You can get everythign you want with either models for well under your budget.

64bit Dual Core AMD
Can have Dual HDD in RAID config
Can have Dual Optical Drives
Slightly heavy (14lbs), louder and hotter than the Clevo M570U (Sager 5760)
Low battery Life
Clevo M570U (Sager 5760)
32bit Dual Core Intel Yonah (possible upgrade to 64bit Dual Core when Merom is released)
7900GTX 256mb (possible upgrade to 7900GTX 512mb as early as July)
Single HDD & Optical Drive
Slightly lightter (9lbs), quiter and coolr than the Clevo D900K (aka Sager 9750)
Approx 1hr 45mins Battery Life with everything on.
If you decide on what I suggested, HIGHLY Suggest buying them from either Powernotebooks.com or DiscountLaptops.com
