Good News!

I crunched some numbers and did some more research. I found all the parts I would need to return are returnable. Here's what I spent:

ASUS Z7S (returned) $480.00
2x Intel Xeon E5405 Harpertown 2.0GHz LGA 771 $450.00
16GB Supertalent FB-DIMM $300.00
TOTAL: $1230.00

Here's what I hope is a better replacement for $60 more:

ASUS Z8PE-D12 Motherboard + E5520 combo $720.00
OCZ Platinum 12GB (6 x 2GB) 240-Pin DDR3 SDRAM DDR3 $200.00
1x Intel Xeon E5520 Nehalem 2.26GHz LGA 1366 $380.00
TOTAL: $1300.00

I will still use the RAM cooler and SSD's I bought + the other equipment currently being employed. Does this sound like a better way to spend $1300?
