Building a new pc, what to do..... what to do.......

[Cyber Akuma]

Im planning to build a PC, I want it to be close to top of the line without hopefully hitting over the 2K mark in price.

Heres my current plans:
Intel Pentium 4 2.5ghz CPU - $250
EIDE 120 GB Harddrive - $130
EIDE 120 GB Harddrive - $130
EIDE DVD-ROM - $60
EIDE DVD+RW - $350
Superdisk Drive - $17
EIDE Zip 250 Meg Drive - $50
GeForce4 TI4600 - $300
Sound Blaster Audigy EX Platinum - $170
ATI TV Wonder VE - Taken from old pc
GA-8IEXP Motherboard - $130
SF-201 Case - $150
VisionTek 512MB PC2100 DDR-SDRAM - $101
---------------------------------------
Total - $1838

Yeah I know, the price is close >.<

Anyway, so anybody have any suggestions?

Main concern is my ram, should I get DDR or RDRam? Some day DDR is better and some day RDRam is better. But a 512meg 1066 chip of RdRam costs 450 last I checked, more then ANY OTHER COMPONENT OF MY PC. Is there really that much of a performance difference between reram 800 and 1066?

Thanks for your opinions (and PLEASE don't turn this into a AMD vs Intel war I am sick of them)
