Hi again guys, getting to the moment of purchasing my build but have come across a few questions.. Here is my planned setup so far:
GPU - Sapphire ATI Radeon HD 4870 512MB GDDR5 TV-Out/Dual DVI/HDMI (PCI-Express) - Retail
Processor - Intel Core 2 Quad Q9550 LGA775 'Yorkfield' 2.83GHz 12MB-cache (1333FSB) Processor - Retail
Monitors - 2X LG L207WT 20" Widescreen LCD Monitor - Black
PSU - Corsair TX 750W ATX2.2 SLI Compliant PSU
Motherboard - Gigabyte GA-X48-DS4 Intel X48 (Socket 775) PCI-Express DDR2 Motherboard
Optical driver - Asus DRW-2014L1 20x DVD±RW IDE Dual Layer Lightscribe ReWriter (Black) - OEM
Case - Antec Nine Hundred Ultimate Gaming Case
Memory - 2X Corsair 4GB DDR2 XMS2 PC2-6400C5 TwinX (2x2GB) - 8GB total
HD - Western Digital Caviar Blue 640GB SATA-II 16MB Cache - OEM (WD6400AAKS)

i was wondering:

1. would it make much of a difference if i went for faster memory (eg 1066 instead of 800) and will my setup be able to support it?
2. does it make a difference if i get 4X2GB memory chips as opposed to 2X4GB, and if so which is best?

p.s this is for vista 64

any other critique of my build most welcome,

Cheers lads!!

Good plan.
1) There is negligible value from faster memory. The Core 2 processors are not sensitive to ram speeds. You are looking at 1% difference in applications, if that. For overclocking to the max, faster ram can help.
2) Go to the Corsair web site configurator to see which modules are compatible with your mobo. Some mobo's are very sensitive to ram construction. My guess is that 4x2gb would be better because they have been out longer.

1) As geofelt said, not much difference unless you want trouble-free high-overclocking (keep in mind that DDR2-800 can be used up to 400MHz FSB without even being overclocked).
2) Make sure your MB will support 4GB modules. The only difference I guess, is that with 2x4GB, you will still have room for another 2x4GB for a total of 16GB ... I hope it takes a while before it is needed .... Windows 7 in 2009-2010 ... D'ho!

BTW, if mostly for gaming, it could be more beneficial to drop the X48 board for a P45 and use the money to get a 4870x2.
