No, I am not an "expert" on RMBS memory. I believe however that to take advantage of the unique features of RMBS, software will need to be modified, and I fear that is a lengthy process. You should ask Carl Bilow on the Rambus thread which buy is the best for the type of applications you intend to use your puter with. Zeev

Ork, for Pentium 4 systems specifically, RDRAM is faster than DDR SDRAM. But the performance difference really isn't that noticeable to the average user. It's up to you. If you'll end up spending less on the RDRAM-based system, go for it. Just know that if you want to upgrade your memory capacity later on down the road, you'll be paying more for RDRAM than you will for DDR SDRAM. Tenchusatsu

orkrious, any PC you can buy today provides HUGE performance overkill for traditional PC activities. For example, If the most intensive thing you'll do is to run several stock tracking and trading applications at once, you will never see ANY difference between newer-model PC's. The only thing for which performance matters any more is 3D games. Many of the current games can actually fully tax the most powerful PC's available. The more powerful the PC, the higher the frame rates and the higher the screen resolution you can use. For 3D games, obviously the video card matters most. The Nvidia GeForce4 cards and the ATI Radeon 8500 are the current leaders. HOWEVER, many games (maybe 25% of current releases) are performance-limited by the cpu/memory subsystem rather than the video card. So this is the ONLY place cpu/memory really matters: for a small subset of the latest 3D games. For example, I like 1600x1200 with frame rates at least 30fps. I had to get a Pentium 4 2.4 system in order to achieve this with two of my favorite games. So, getting to RDRAM. If you check out the most recent benchmark results for 3D games specifically, it is clear that the advantage of 400 MHz RDRAM (the mainstream kind on the market right now) over the fastest DDR is pretty much zilch. DDR has got faster recently, and has lower latency. (However, if Dell has started selling 533MHz RDRAM systems, you can see from the link that there is some speed advantage for that over DDR). www6.tomshardware.com Another consideration: "home" systems are generally designed to run quieter than "business" ones. The typical office environment is pretty noisy, so people don't notice PC noise. RDRAM memory and motherboards run a LOT hotter than DDR ones, which means more fan noise for the cooling.
