I'm building a new gaming PC soon and have been browsing extensively on newegg, tom's hardware, hardocp, etcetera for information about it. What I have been able to find out very little information about, however, is comparison of current RAM speeds. My question is, is DDR3 really that much faster than DDR2 to justify the price jump? Please let me know what y'all think or have found out about this. Thanks.

No, not now at least. The benchmarks show very little performance if at all over the current 1st generation DDR3 offerings. Remember when the 1st generat DDR2 came out? DDR2 400 was slower then DDR1 400 due to the high timings that came with the 1st generation DDR2's. It took the 2nd generation of DDR2 (DDR2 667) to finally overtake the 3rd generation of DDR1 (DDR1 400) in performance. The same applies to the 1st generation DDR3 vs the 3rd generation of DDR2. You are much better off with DDR2 right now, just in price alone.

The exception to what Cobra has stated seems to be in the realm of Graphics cards. DDR3 seems to be the way to go with graphics cards.

"DDR3 seems to be the way to go with graphics cards" Actually, it's GDDR3 that's used in graphics cards, which is different than DDR3. http://en.wikipedia.org/wiki/GDDR3 "And that's the fishing line, because Sharkboy said so!"

Thanks for the correction jam. I probably shouldn't comment on anything to do with graphics cards as I am not a gamer so don't keep a close watch on the technology.

Yes DDR3 and GDDR3 are two diff things.
