help in memory choices?

[Blanks]

Well here is my current build so far....

Kingwin-424-B-VM Case w/ 80mm Blowhole
ASUS P4C800 E Deluxe
P4 2.8C MO w/SP-94 Heatsink w/ 92mm Tornado Fan
Swiftech MCX159-P Chip Cooler for NB
Creative SB Audigy 2 ZS
2 WD 36.7 Raptors
Lite On LTR-52327S Black 52x32x52 CD-RW Drive, 2MB, OEM
LITE-ON XJ-HD166/XJ-HD 165H 16X DVD ROM Drive BLACK
MITSUMI D359M3 BLACK FDD 1.44MB 3.5INCH - OEM
ENERMAX Noisetaker EG475P-VE-SFMA. 470W

Plan on overclocking and am thinking of getting 1 Gig Corsair XMS 4000 Pro or 1 Gig of Corsair XMS 3200 LL Pro. Which do you recomend and why? Plan on getting the Hercules Radeon 9800 Pro and XP Pro. Thanks for all your input

most 2.8C will not run at 250 mhz which makes it hard to use pc3200 with a divider so i would get the 4000 so you can run 1:1

isnt the xms series tested on the p4c800 e deluxe. with the 4000 pro i should be able to get a decent overclock right?
