i am wondering if the DDR2 800 ram will last for at least few years or shall i go with the ddr3 ?? I am planning on building a new PC

I've been wonderng this same thing. If I was building a computer today, I'd go ahead with DDR2 ram. If I was building in a few months, I'd probably go with DDR3. While DDR3 doesn't show any real advantage right now, given some time in developement, it will no doubt get faster.

DDR3 is only worth it if you buy the fastest you can get and overclock like insane. The current Intel processors don´t really benefit from DDR3. The worst thing about DDR3 is the price though. I wouldn´t bother and check back in a year or more.
 

Intel's 33/35 mobo's dont require DDR3. The X38 may require DDR3 but may not be out until the end of 07. Intel will not force DDR3 support until mid 08 atleast in mainstream 33/35's and AMD 09 with AM3. That said we may see DDR2 900 or 1000 replacing DDR2 800 as the preferred speed. AM2+ may well go for DDR2 1000 as AMD has tried to get JEDEC to change 1066 as a DDR2 standard but failed.
 
Sure, DDR2 will last for more than a few years. Heck, there are still loads of machines with DDR let alone DDR2. But, since you are planning on a new build, I would go with DDR3. Even though latencies are high, it's only a matter of time until latency drops and DDR3 reaches insane speeds. When DDR2 first hit the market the latency was horrible with DDR machines besting DDR2, but that changed as DDR2 became the mainstream, DDR3 will follow the same trend.

All things considered though, I'd wait until next year before fully jumping on the DDR3 bandwagon, until more procs and mobos are on the market that take advantage of DDR3.

DDR2 is still the standard, and anyway:

2GB DDR2 now: $85, new mobo & DDR3 you want in a few years $250
2GB DDR3 now: $415

@systemlord
Please educate your self regarding overall latency (in nanosecond) as frequency increases here

@OP
Till people wanting to reach FSB above 650Mhz which might be possible with 45nm Core2s.

The fact that right now DDR3 is not much better than the best DDR2 dimms out there. Plus DDR3 prices are high right now. I have better latencies @1200MHz @5-5-5-15 48.1ns than @800MHz @4-4-4-12 54.8ns, DDR2 will be around for one 1/2 two years. DDR2 is in its prime right now and at the limits as far as MHz go's.

I'm also building a new system as well and staying with DD2 for now with the Gigabyte GA-P35-DS3R. Personally, I'd stick with DD2 for now because of the high cost of DDR3 and if you game, just by looking at the FPS, I wouldn't think that you'd see a bigger difference in DDR3 than 2 ( see link below). What you could do trencin is get the Gigabyte GA-P35C-DS3R mobo. It has DDR2 and DDR3 slots. It will give you the advantage of upgrading to DDR3 when the prices come down and the chips get better. I didn't go with the GA-P35C-DS3R because I'm expecting to get at least a year out of my GA-P35-DS3R then upgrade to a X38 or better mobo in the future. Here is a short post about DDR2 and DDR3.

Alright so If I want to build a system within the upcoming weeks it would be perferable to get the DDR2 not only because of its price but also because of it being a standrad in many Motherboards in my case going AM2/AM2+ DDR2 800

I think Penryn will make use of that very high speed DDR3 has to offer. For the Core 2 Duo E6600 and up DDR2 is best. I believe Penryn will make use of DDR3 and not the current Core 2's.

OCZ Introduces DDR3-1800

DDR3 is improving, at some levels it is now better than the fastest ddr2. Cheap? No. Slow? No.

I believe DDR3 is best for Penryn, but current Core 2 Duo's (6000 series) are doing just great with the DDR2 thats out there. There comes a point where more bandwidth has not much returns, apps out there now aren't going to perform "hugely" better using DDR3 in my opinion. But is a step in the right direction.
