With the spec below -
Intel Core 2 DUO E6400
Asus P5N-E SLi nForce 650
BFG GeForce 8800 GTS OC 320MB
Shall I get the -
Crucial Ballistix 2GB (2x1GB) DDR2 PC2-6400C4 800MHz Dual Channel Kit (BL2KIT12864AA804)
Or the -
Corsair 2GB DDR2 XMS2-6400C5 TwinX (2x1GB)
Or lastly the -
GeIL 2GB (2x1GB) PC5300 667MHz Value DDR2 Dual Channel Kit (GX22GB5300DC)
So many to choose from
I have done a fair bit of reading but it lead me to confusion more than anything lese 
I'm leaning towards Ballistix atm
Thanks
