Which RAM to Choose Pls??

Hi TSF Team. :wave:

I am shortly to order a new computer to be built for me, but I have a question on which memory (RAM) to select as both seem to be compatible with my mbo and CPU.

My proposed mother board is a Gigabyte GA-EP35C-DS3R, with an Intel CORE 2 DUO E8400 3.00GHz 6MB, 1333FSB, LGA775

My memory choices are:

TWIN2X2048-6400C4 DDR2-800 (XMS2-6400C4) 2GB Kit (2 x 1GB) 2.1v 4-4-4-12-2T (TWIN2X2048-6400C4 2GB Kit (2 x 1GB) 4-4-4-12-2T 240pin DIMM Black)

Or

TWIN2X2048-8500C5D DDR2-1066 (Dominator-8500C5*EPP) 2GB Kit (2 x 1GB) 2.2v 5-5-5-15-2T (TWIN2X2048-8500C5D 2GB Kit (2 x 1GB) 5-5-5-15-2T 240pin DIMM Dominator)

Given there is very little difference in cost (a few $s) - which is the better choice - the 1066 with higher latency or the 800 with lower latencies??? :4-dontkno

Any advice would be very welcome
