DDR3 build or DDR2 build, you decide.

Hey everyone,
I'm building a rig to do a lot of HDV editing, Photoshop, After Effects, etc.
I was looking into both DDR3 and DDR2. Out of these two builds which one do you think will perform better and offer highest return on my investment?
By the way, I'm planning on overclocking the Q6600 to around 3.0Ghz. Do you think it will work with the following builds?

DDR3 Build:

ASUS MAXIMUS EXTREME LGA 775 Intel X38 ATX Intel Motherboard - Retail $349.99
http://www.newegg.com/product/prod [...] 6813131235

Intel Core 2 Quad Q6600 Kentsfield 2.4GHz LGA 775 Quad-Core Processor Model HH80562PH0568M - OEM $199 (just purchased from Microcenter!)
http://www.newegg.com/Product/Prod [...] 6819115018

Patriot 4GB(2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) Dual Channel Kit Desktop Memory Model PDC34G1333LLK - Retail $359.99

or

DDR2 Build:

DDR3 Parts: $908.99
DDR2 Parts: $533.98

Difference: $375

Thanks for your help and suggestions.

I have an Asus Maximus Formula, 4GB(2x2) DDR2 and a Q6600, no reason to go for DDR3 Just yet so stick with DDR2 especially with the prices there going for at the moment.

The memory fabs went overboard when predicting the demand for RAM when Vista was released, and the slow adoption rate left the channel packed full of supply.

DDR3 is nutty expensive, I am guessing, to allow the fabs to clear out DDR2 inventory, so they keep prices high.

Also, was it me or was DDR2, for pretty decent latency, short-lived? Just seems like yesterday everything was all about DDR1.

I just don't see any performance benefit when 4GB can run you 500$ I mean, you can change platforms later on for that savings by going DDR2.

yeah, actually scottoliver, you make me worried.... I am thinking of grabbing 8GB of DDR2 for my next build, and leaving it in a drawer. If the channel runs dry I'd have to donate a kidney to go 8GB DDR3.

Everywhere I look, amazing quality DDR2, almost for free.

I OC'd my Opteron 165 from 1.8Ghz to 2.73Ghz using value-bin Crucial Rend RAM, 2Gb in Dual Channel. Without touching the voltage or the timings on the RAM. (I am not THAT experienced OC'ing).

This was with the stock cooler, I think the RAM you want would only be limited by your skill in OC'ing.

I don't know how much harder it would be to OC if you have all your memory slots full though...

Overclocking your computer and its main use is high definition video editing is not a wise decision, unless you don't mind artifacts in your edited video.

The X38MCH with DDR3 provides the widest and fastest bus transfer speed between the processor and memory.

The motherboard you chose seems too expensive by $60 to $80.
I would skip the Q6600 and purchase a cpu with a 333MHz core clock (1333 FSB). Too bad you already purchased the Q6600. A processor with greater L2 cache will improve (decrease) the time it takes to process video.
The 4GB Patriot DDR3 Kit (PDC34G1333LLK) is an excellent choice and the price is good too.

I think a 3.0Ghz OC is not asking much from this Q6600 and from what I've heard it's very stable. I still want to OC this system and edit HDV.
I'm sticking with the Q6600 of course because I've already purchased it.
