2GB DDR500 vs 4GB DDR400?

[Techno]

Hello,

My Current "DAW" (used for Audio/Video editing):

Athlon 64 X2 3800+ (@ 2400Mhz)
EPoX 9NPA+ SLi
4GB PQI (samsung chips) PC3200
2 evga 7800GT in SLI
2 NEC 19" CRT Monitor

In haivng this system, I've found that I don't need SLI and I'm not using all 4GB under Windows XP Pro (non 64 bit). Not all the software and hardware for my DAW has 64Bit drivers so I'm stuck on regular Windows XP Pro. Anyways... I'm upgrading my PC once again to get even more speed out of it for the A/V use of the PC. I have already ordered the new DFI Lanparty UT CFX3200-DR motherboard from newegg. I know I won't use SLI in it, but it will allow me to use both video cards in single mode thus being able to use up to 4 monitors. I'm also gonna buy 2 Gigabyte I-RAM cards and memory to max them out. And thats where my question comes in. Since I don't use all 4GB of my memory, I'm thinking of taking my current memory and sticking it into one of the I-RAM cards and then buying another 4GB for the second and maybe buying 2GB of DDR500 since I have a REV E6 X2 CPU. But I'm wondering if its worth it cause I can get 4GB of PC3200 for the same price as 2GB of DDR500.

Thanks!

I'd expect CPU speed and disk I/O to matter more for video editing than a small difference in memory bandwidtb, but you should try to find benchmarks of the programs you use (not just generic benchmarks) to confirm this.

i have a daw w/ an opty 1.6 oc'd to 2.6 and a day non oc'd with a 3800... considering the small price difference, i would DEFINITELY go with an easily oc'd 165 for your next setup. on the opty box, I can run like 16 tracks loaded w/ plugins and it barely touches the cpu.... insane.
