Noob building first custom...need mobo advice

Ok so i'm getting my first custom built comp and i'm having trouble deciding which mobo would be the best for me...i'm buying a barebones system, so i only have a few choices on what to get...i've already purchased most of the components that i'll be installing...here is what i've bought so far:

Seagate Barracuda 7200.11 ST3500320AS 500GB 7200 RPM 32MB Cache SATA 3.0Gb/s Hard Drive

SAMSUNG Black 20X DVD+R 8X DVD+RW 16X DVD+R DL 20X DVD-R

G.SKILL 4GB(2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory

EVGA 512-P3-N802-A1 GeForce 8800GT Superclocked 512MB 256-bit GDDR3 PCI Express 2.0 HDCP Ready SLI Supported Video Card

Now here are the board choices i have... i'd like a board for gaming, one that i can use the above components in...i'm not really interested in ocing or anything like that...but i'd like a board that will last me a good 3-4years...also i'm planning on getting the Q6600 as my processor...anyway here are my choices:

Gigabyte GA-P35-DS3L P35, 1333FSB, PCI Express, DDR2, Sound, 1Gb LAN

ASUS P5K SE P35, 1333FSB, PCI Express, DDR2, Sound, 1Gb LAN

ASUS P5N-E SLI nForce 650i, 1333FSB, SLI PCI Express, Sound,1GB LAN, iEEE

ASUS P5B-E P965, 1333FSB, PCI Express, DDR2, Sound, 1Gb LAN, iEEE, Quad

ASUS P5N32-E SLI Plus nForce 650i, 1333FSB, SLI PCI Ex, Sound,1GB LAN, iEEE

ASUS P5N32-E SLI nForce 680i, 1333FSB, SLI PCI Ex, Sound,1GB LAN, iEEE

eVGA 122-CK-NF68-T1 nForce 680i, 1333FSB, SLI PCI Express,1Gb iEEE

so any suggestions on what board would be the best?...thanks...

I am finishing an install on a new PC for my cousin as we speak, using the Gigabyte! I recomend it.I have an ASUS Striker in my own PC, nightmare to get running properly, the Gigabyte was a treat. I know where my money will be going next time.

the only thing is the gigabyte doesn't support sli...i'm only buying one card as of now, but i like the option of being able to add another if i choose too...
