I'm just about to order an "EPoX EP-8RDA+ nForce2 Socket A Mainboard" but I'm not sure what type of DDR ram to buy.

I was about to buy some Crucial DDR sticks:-

512MB CT6464Z335 DDR PC2700 CL=2.5 Unbuffered Non-
parity 6ns 2.5V 64Meg x 64

which seem a bargain at 89.99

but then I saw some Cosair DDR:-

Corsair Platinum Series XMS2700 333MHz CL-2 512MB DDR 'Memory with Muscle' Ultra Fast CMX512-2700C2 333MHz 2-3-3-6-T1 184-Pin DDR-SDRAM DIMM

but its really expensive at 162.14 inc.VAT

Which RAM would be the most appropriate?
