bulding a gaming rig ...just need help on mobo

hello guys
is are the specs

-LG 22X DVD±R DVD
-Thermaltake M9
-Seagate Barracuda 7200.10 ST3250410AS 250GB
-CORSAIR CMPSU-750TX 750W
-Intel Core 2 Quad Q6600 Kentsfield
-EVGA 01G-P3-N891-AR GeForce 9800 GX2
-OCZ Platinum Revision 2 2GB DDR2 800 4-4-4-12

all this for $822 but i just need the mobo i reallly dont want to exceed from $1000
im looking for an asus750¡ or 680¡ from evga my only complain is that asus750¡ has the pcie2.0 slots to close for gtx 280sli (ohhh said gtx280 because i will buy the 9800gx2 and i know someone who can buy it to me for 400 and i might buy another gtx280 later) the evga 750 is about 40 dollards more than asus .....

soooo....and about the evga680i heard it was to bugged..... and i ve looking this option too.. buying an asus 780¡ but it will cost about 1035 the grand total ( i dont know if that is a better mobo) if it is and it is worth it i guess i ll have to save a bit

but is it worth having the asus 780¡ .. i guess i will oc the q6600 to 3.0 or above and i will be using a single card for a year i might have sli a year later

so confusing

yeaa i might have the cpu the whole time until I make another rig ....so you said is better the 680i ...what about the asus 780¡??

does the evga 750 ftw has problems with sata ports ????
