Ddr3 board worth getting?

Hi im currently working on building a new system and i'm trying to decide which mobo to go with, my main concern being ddr2 vs ddr3 ram. it seems like its not far off that ddr3 will be the standard and ddr2 dead, so im wondering if its worth investing in a ddr3 board. here's the two board im looking at:

intel ddr3 1333

gigabyte ddr2 1333
http://www.newegg.com/Product/Prod [...] 6813128358

i want this computer to last me a long time, my last computer has lasted me 6 years and id like this new one to last as least as long. if there's any recommendations besides these two boards as well, i'd love to hear them.

ok so i did some reading and decided ddr2 is the way to go, but now im torn between two boards:

Gigabyte EP45-UD3P
http://www.newegg.com/Product/Prod [...] 6813128358

Asus P5Q Pro
http://www.newegg.com/Product/Prod [...] 6813131299

both are 775 socket, P45 bridge, both really just very similar boards. The gigabyte can take up to ddr2 1333 and 16gigs of ram, the asus only ddr2 1200 and 8 gigs of ram. other than that, very similar. i've also heard the asus and gigabyte are the two best board companies, so really either one would be a good choice.

what i'm mostly concerned with, is which one will be better for overclocking? get me higher numbers.

my setup on this new comp for a bit will be:
Intel Core 2 Duo E8500 3.16 Gighz
1 gig Crosair ddr2 800 ram (will soon upgrade to 4 of 1066 or higher)
Nvidia 8800 GT (possibly gts or gtx, i'm buying it off of my friends brother and i dont remember which one it is)
Crosair TX850w PSU (12v70a single rail)
Seagate 500 gig 7200.11 HDD

i realize its not the most up to date rig, but it'll be a vast improvement on my current (p4 3.0, 4 gigs ddr 400, radeon 9800 pro) and seems like a very overclockable rig.

also, what would be a good cooling option on the cpu for this?

Either mobo is good for OCing.

Massive overkill on the PSU considering the mobo won't do SLI. A good quality 400W can easily run that system.

nevermind i figured that out, and yeah the psu is a bit of overkill but it's on sale on newegg for the next few days and will last me forever with how much power it has. that and the board can do crossfire, which i could end up doing one day if i switch to an ati card who knows.

well the TX850 is only 20 bucks more for 200 more watts and 12 more amps on the 12v, which seems like a good deal.

it's 20% off until the 12th, and then a 20 dollar rebate brings it down to 100. i want a power supply that'll last me forever, that one should get pretty close.
