Hey Guys/Gals,

Comments welcome. Am considering the following:

Dimension 9100
-----
Pentium® D Processor 820 with Dual Core Technology (2.80GHz, 800FSB)

Options are:
Pentium® 4 Processor 630 with HT Technology (3GHz, 800FSB) [subtract $100]
Pentium® D Processor 830 with Dual Core Technology (3GHz, 800FSB) [add $170 or $5/month1]
Pentium® D Processor 840 with Dual Core Technology (3.20GHz, 800FSB) [add $410 or $11/month1]

Which would be better to get, the 630 or the 820?
-----
1GB Dual Channel DDR2 SDRAM at 533MHz- 2DIMMs
-----
Dell USB Keyboard
Dell® 2-button USB mouse

Those are probably crap, but I have ones I use anyways.
-----
250GB Serial ATA Hard Drive (7200RPM) w/DataBurst Cache™
-----
Single Drive: 48x CD-ROM Drive (gonna trash that)
-----
128MB PCI Express™ x16 (DVI/VGA/TV-out) ATI Radeon X300 SE HyperMemory (gonna trash this and get either the 6600 GT or the 6800 GT)
They DO offer the 256MB PCI Express™ x16 (DVI/VGA/TV-out) nVidia GeForce 6800 [add $180 or $5/month1] but I don't think it's a good deal... comments?
-----
Sound Blaster® Live! 24-bit ADVANCED HD™ Audio

or should I just stick with Integrated 7.1 Channel Audio [subtract $29]
or Sound Blaster Audigy™2 ZS (D) Card w/Dolby 5.1, and IEEE 1394 [add $51 or $1/month1]
-----

Thoughts?
