just like acilikola said, i recently did the same thing for a fairly good price. but i purchased form where monica mentioned, cyberpowerpc. i had the same budget as you, and made off with :
CD: 8X DVD Rewritable Drive (NB-348-DVDRW)
CPU: Intel® Core™ i7-740QM Processor 1.73 GHz 6M Intel Smart Cache PGA988
HDD: 500GB 5400RPM SATA300 Hard Drive
HDMI: Built-in HDMI Port
MEMORY: 8GB (4GBx2) DDR3-1333 SODIMM Memory
MOTHERBOARD: Intel HM55 Chipset Mainboard
NOTEBOOK: Compal NBLB5 Notebook 15.6" W-LED 1366x768 Display w/ Built-in 1.3 MP Webcam
OS: Microsoft® Windows® 7 Home Premium (64-bit Edition)
VIDEO: ATI Mobility Radeon HD 4650 GDDR3 1GB PCIe 3D Video
and of course ..wifi

total price is $1,213 before tax and shipping. obviously i changed ram to 8gigs like acilikola. as you can see, what you need is basically what youre given for the dollar amount. just my two cents. good luck and happy hunting heheh
