New Build, could use some advice

I'm putting together my first gaming rig and need some advice!

Some thing to note:
I'd like to run SLI in the near future, but not off the bat, so i'd like to make sure everything is compatible for that.
The only hangups i'm having atm is which RAM and PSU to use, advice on this would be greatly appreciated!

I agree on the E8400 and the Corsair PSU. It's a good deal here;

If you want 750 watts go with this;

Yep! go with the Crucial, meant to comment about it, just forgot, it's bedtime!

Well the 1066 DDR2 is fine, but if your not going to do much OC'ing the DDR2 800mHz CAS 4 stuff for about $75 - $35 MIR is good too. It'll still leave plenty of room to OC, if you decide to do that and will save you some $ in the process.

I'd 2nd/3rd the Corsair 620hx and the e8400. Just might want to double check that the 680i mobo is supporting Penryn chips. Not sure if they are or not. I'd probably go with a 750i or 780i mobo, since it's close to the price that your currently looking at.
$157 shipped and has PCI-e 2.0 slots, which is better than the 680i's:

or for $260 shipped:

If you don't go for SLI than a p35 mobo would be just fine too. I'd go with a Gigabyte DS3R/Abit IP35/Asus P5k ones, if I was going with a p35 based mobo. You can decide, but that is the direction that I'd go.

Edit: There are the x48 mobo's that have started showing up recently. I think that they are a viable option, except that the do Xfire and not SLI, so if your set on nVidia than this option would only be good if your only using 1 nVidia GPU. Just thought I'd throw that out there for consideration.
