which is best for my setup

[Po_Pwide]

Having to get some new ram, games is top priority (bf2) so bare that in mind, my setup is in my sig:

was looking at these
G.Skill 2GB DDR ZX PC3200 (2x1GB) £129.95
G.Skill 2GB DDR HZ PC4000 (2x1GB) £124.95

but not sure which is best, says they are recommended for socket 939 but will they still run on 754.

Thanks Po
