[props]

i'm building a new system right now and still undecided on a couple of parts
mainly the motherboard and ram so i need some help/suggestions.
i'm switching back again to the 64 athlon chips as i've pushed this intel3.2e to the max. so anyways here are the main components
Antec Sonata II Case Piano Black[no psu]
Ocz 600watt PSU
AMD Opteron 148 with the CABYE stepping
2x 16X DVD Drive/Burner
2x EVGA 7800GTX 256MB
so heres the part i'm having issues with
for the motherboard
DFI LANParty NF4 SLI-DR ATX S939 NFORCE4 SLI DDR 2PCI-E16 SATA2 RAID Sound GBLAN 1394 Motherboard [Great motherboard]
or
DFI LANParty UT NF4 SLI-DR Expert ATX S939 NFORCE4 SLI DDR 2PCI-E16 SATA RAID Sound LAN Motherboard [Even better motherboard but some issues of killing cpus by sending 3+volts to the cpu core]
and heres another issue i'm having
i want to put in 2GB of ram thats capable of running at low timmings and be able to clock at high fsb.
should i go for the
Mushkin Redline PC4000 2gb?
or the OCZ Platinum EB PC4000
or should go differ route??
and oh yeah do you guys know where i can get some deals on these? heheheh
