Any Suggestions On My Rig?

ok the system i have atm is:

QX6800 EE @2.9GHZ
2GB Corsair XMS2 8500
P5N-32 Deluxe Motherboard
2x 7950GX2 512MB in Quad SLI (when it works which is not very often)
2x 150GB Raptors in Raid-0
Creative Base 7.1 Sound Card

The rig is getting 8234 on 3D Mark 06 i was getting 11k or there abouts when it was new however even after a full re-format its not benchmarking fully :angst:

added to that 90% of the time it blue screens in 3D Mark 06 when Quad SLI is turned on otherwise its fine.

Anyway the new rig i am thinking of ordering

Intel Core 2 Duo E8500 LGA775 'Wolfdale' 3.16GHz (1333FSB)
OCZ 2GB DDR3 PC3-10666C6 1333MHz ReaperX (2x1GB) Dual Channel DDR3
Asus P5E3 Premium/Wifi@N Intel X48 (Socket 775) PCI-Express DDR3 Motherboard
EVGA GeForce 8800 Ultra SuperClocked SILENT 768MB GDDR3 HDTV/Dual DVI (PCI-Express)
PC Power & Cooling Turbo Cool 1KW-SR 1000W Power Supply
x2 in Raid-0 Samsung 64GB 2.5" SATA Solid State Hard Drive
Creative Sound Blaster X-Fi Xtreme Gamer 7.1 Sound Card
Lian Li PC-A10B Aluminium Full-Tower - Black
Freezer 7 Pro CPU Cooler (Socket LGA775)
D-Link DGE-528T Gigabit Desktop PCI Network Adapter
LG GSA-H55NBRL 20x DVD±RW IDE Dual Layer ReWriter

Its worth noting that i will be overclocking it also the reason for the small amount of HDD space is the only thing going on here is games and then its

only the ones i am playing i have a server with 1TB of space for all my other stuff

The other 2 motherboards i am looking at is

EVGA 132-CK-NF78-A1, NF780i SLI, 775, PCI-E 2.0 (x16), DDR2 1200/667/800MHz, SATA II, SATA RAID, ATX
Asus P5K Premium/WiFi-AP Intel P35 (Socket 775) PCI-Express DDR2 Motherboard

depending on the board depends on the RAM oh one more thing when the new Geforce 9 cards come out i will be wanting to upgrade to one of them at some

point

so just wondering if anyone could see any problems or suggest one of the motherboard or anythnig else thanks:)
