Yet another do I have enough juice thread

I'm working on my ESXi rig and I've ran myself (maybe) into a hole. I've thought about going from a C2D quad to a dual dual core LGA 771 system. The PSU I have is an NSPire NSP-405V2.0F12.

Proposed system specs:
Intel S5000SPL mainboard (yes I know i'd need a converter for the 8pin)
4 500GB Western Digital Blue single platter HD's in RAID 0 (.65A 5V and .5A 12V)
LSI Megaraid 8308ELP SAS card (PCI-E 4x) that staggers the spinup of the drives.
Dual LGA 771 5140 dual core xeon processors (2.33Ghz dual core x2, 65nm)
1 DVD-RW Sata drive (rarely used, only when ripping or loading iso's into esxi)
8GB (2x4GB) DDR 800 FB-DIMM, possibly going up to 16GB (4x4GB DDR800 FB-DIMM)

The system is running ESXi, so it's not going to be hard core flogged. It's a test rig, not an enterprise system.


The PSU specs are as follows:
3.3V at 18A (peak 25A)
5V at 28A (peak 30A)
+12V1 at 18A (peak 20A)
+12V2 at 18A (peak 20A)

12V1+12V2 max 27A (peak 31A)

Continuous power 405W, peak power (for 60 seconds) 505W.

Is it enough? I want to say it is as I have a WHS server that's pulling 110W from the wall idle and 185W under full load in WHS. It has:

Athlon X2 5800+
2GB DDR2 800 RAM
2x2TB WD Green drives, 1x1TB Seagate 1TB, 1x320GB WD 7200 RPM, 1x160GB WD 7200 RPM
1 SATA DVD-RW
3 120mm fans, 1 92mm, 2 80mm.
 
The PSU is fine for wattage, but if it's in your budget I'd highly recommend a good quality PSU such as Seasonic or Corsair or Antec.

I'm also curious--why the switch from quad core to 2x dual core?

I'm still trying to define it. Going by CPU benches, it takes at least a Phenom II X4 810 or Phenom X4 9950 or a i5-660 to match the performance of dual 5140 Xeon dual core processors. And that is just matching CPU cycle advantage. That still doesn't take into account that I'll have an extra 4MB of cache and higher memory bandwidth, and memory capacity (supporting a max of 32GB on a server board). But compared to paying 160$ for two 5140's, what could I get in terms of quad core processors. An i7-720 would be awsome but it's wayyy too much money.
