P4 mobo with rdram 1066 or mobo with ddr and agp8x

hey all...

I am planing to assemble a p4 system and with this new agp3.0 (8x) thing coming around the corner i was wondering what would give me the most performance, a mobo with rdram 1066 support or a mobo with agp 8x and ddr support? I've heard that rdram is the ultimate performance for the p4, but if ddr is slightly slower i rather have the fancy of agp 8x. also... is agp 8x really that fast compared to agp 4x? thnx in advance

Welcome to TechIMO!!!

AGP Modes
1x (266Mbps) (8 bytes per two clock cycles)
2x (533Mbps) (8 bytes per clock cycle)
4x (1.07Gbps) (16 bytes per clock cycle)
8x (2.1Gbps) (32 bytes per clock cycle)

I'd say so!

I don't think I've seen any video cards that use 8x AGP at the moment, so I'm assuming you're not starting your build until they start showing up? For now, I'd say go w/ DDR, 4x AGP, and a Ti4600 or something.

if you are thinking go with pc2100 memory on a i845 based board then id say go for RAMBUS. the pentium 4 runs much better with rambus as the cpu likes the high bandwidth it can give.
if you decide to run DDR then go for pc2700 333 memory and a sis or via chipset that can handle it and a 133mhz fsb pentium 4.
there is only one card out at the moment that supports AGP X8 by sis i dont think Nvidia and ati will use AGP X8 until later on next year.

Abit makes a P4 board supporting the 400/533 mhz bus and AGP 8.0 with ddr support of pc2700. Oh, and read up on the Radeon 9700. It is AGP 8.0 compliant. Cheers
