Upgrading from i3 to i7 - reasonble setup?

I'm looking to upgrade my i3-540 to something from the i7 lineup in hopes of speeding up my rig for gaming (i7-950 or i7-870). I've been trying to figure out a few things but am still a little confused. Any help is appreciated:

-Is there an advantage between an even (2x 4gb ram) vs an odd (3x 2gb) number of ram? I currently have 2x 4gb and I'm wondering if one or the other would work better with an i7?

-After researching I think that in addition to the processor I should probably get 1) a new motherboard, 2) maybe a PSU, 3) maybe odd number type of ram depending on mobo - does this sound right or can I just drop in the i7?

-Is my 550W PSU okay for this. I'm considering another video card in the future for NVIDIA SLI, would an 800w PSU be a good idea or would the one I have be okay?


My current setup:

Motherboard option 2 (if needed - might be better, but would I need different ram?): EVGA 131-GT-E767-TR LGA 1366 Intel X58 SLI 3 SATA 6Gb/s USB 3.0 ATX Intel Motherboard
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

PSU (if i need one): CORSAIR CMPSU-850TX 850W ATX12V 2.2 / EPS12V 2.91 SLI Ready CrossFire Ready Active PFC Power Supply

Thanks!

I would say - wait for a two weeks for Sandy Bridge and then decide.

You can put an i7 8XX in your current board not a 9XX, an i5 760 should make your system balanced though.

I was just checking out the i5 2500 and it looks really nice, would I still need a new mono or anything to optimize? I'm not looking to upgrade after this for a while.

The i series that have 4 digits in the no are a new chipset again so you will need a new Mobo, your current board can use all i3s with 3 digit nos all I5s with 3 digit nos and all i7 8XX series and nothing else.
