PC components recommendations

Hi,

Looking to picking up a 1TB hard drive and 4gb ram for my MSI P55-GD65 &Core i5 750

HDD wise I am thinking of going for the Samsung F3. I doubt the F4's will come in 1TB size, maybe 1.3TB based on platter sizes.

RAM wise I can't make up my mind between the following two.

CMX4GX3M2A1600C9 - 4GB (2x2GB) Corsair XMS3 DDR3 PC3-12800 (1600), Non-ECC Unbuffered, CAS 9-9-9-24, XMP, 1.65V

TW3X4G1600C9D - 4GB (2x2GB) Corsair Dominator DDR3 PC3-12800 (1600), Non-ECC Unbuffered, CAS 9-9-9-24, DHX, 1.65v

Which would you recommend ? or alternatives ?

Thanks,

Pav

Any thoughts anyone ?

Really doesn't make a difference. 1 has bigger (pointless) heatsinks and will cost more. Up to you.
Dominators are supposedly better overclocking memory.
