Building a core i7 gaming rig... need advice

Hey guys. So I'm about to build myself a new gaming rig but I've got a question about what motherboard/ram to go with.

There's a place here(in canada) called NCIX that has a bundle on a EVGA x58 + 6gb(6x1gb) DDR3-1866 memory for $450

would this be a good purchase or should I get the Asus P6T + 6gb(3x2gb) Corsair DDR3-1333 for ~$500(+ shipping which would be about $20 making it approx $70 more expensive)

I know with DDR2 memory using, for example, 4 x1 gb ram could yield much worse results than 2x2gb but I'm not sure if this will affect DDR3 the same.

So which do you think the best buy would be?

I'll be getting a Core i7 920 with it.. I'm not planning on OCing right away but I may later on
