As you can see, TCCD Sanda mem is showing a whopping ~70% faster vs. the cheapest PC2100 ram ever sold. And 30% more than value ram, PC3000 ram @3-3-3. Will this translate into real performance gains? Well lets see.

Here we see pretty signifigant gains due to bandwidth 41% diff top to bottom. This test obviously is very beneficial to have bandwidth or LL. Update: Crucial Ballistix owning all, Winrar seems the like LL even more than bandwidth. We sorta saw this already by the very close scores of PC3000 LL VS PC4700 high bandwitdh.

Summary
Well there it was. While sandra likes to show whopping 70% increased bandwidth of expensive TCCD it really does'nt translate to real world . Only one area seemed signifigant was winrar. The couple game tests which slow slight inprovement with bandwidth or LL, I think you're much better of upgrading to the next tier of video card if on a budget instead of investing with overpriced ram. Investing in expensive ram probably offers to poorest bang for the buck of any computer part. What's intesting was Ballistix's async 166 and LL the performance faired a little better than TCCD 1:1. Seems A64 prefers LL rather than bandwidth? Also shows that running async is'nt to be shunned.
Course if you want the best, go right ahead and invest in expensive ram, as shown it makes a slight difference in gaming and winrar but I'm sticking with $130 2x512 value ram and use a divider from now on because the price to performance ratio is simply not worth it. IMO You're much better off using that cash for the next level of video card which really does boost performance by ~70% in games.
One other thing of intrest is PC3000 running async 133 at low timings 2-2-2 was almost as good as PC4700 high bandwidth but loose timings TCCD is forced to run at 290Mhz.... many a ram can do ~200Mhz 2-2-2.
Conclusion
Some Games = very slight benefit to using expensive high bandwidth TCCD or expensive LL ram Like Ballistix over value ram. Winrar sees major benefit though, 41% top to bottom.
LAME, Cinebench, ScienceMark, PiFast, Superpi, POV-Ray, DVDShrink shows no or infinitesmal boost above Value ram.
