thanks for gettin back
part of the reason that i went for a core 2 duo is because i'd prefer to keep my motherboard - it only takes socket 775, although it has slots for dual DDR3 (@ 1333Mhz max, i think). hopefully it'll be a while yet until i need an I-series, if i can get half decent clock-age out of some high end core 2 duos.
as for the memory - is CAS latency the same(ish) thing as CAS timings? if so, what exactly am i looking for here? the last time i took an interest in hardware was about 3 years ago, so i'm pretty behind on this stuff D: really, the main reason for picking those modules is because i'm running 2gb on Vista x64, and i've heard about how much smoother it runs at 3/4gb - that, and my current sticks are OCZ and they've done me just dandy so far. like i say, only getting DDR3 cos i can't get usable DDR2 for a reasonable price anyway, and because my motherboard supports it, so unless this CAS is gonna really slow things down (which, given that i'm still running a 512mb 8800gt and a SATA-II HDD, i can't really see happening. but then again, i don't really have the full picture).
as for overclocking the cpu; atm I have something from the 22XX range running @3.1Ghz (up from 2.0 or something), so while + .1 of a Ghz at standard isn't all that much difference and i might see little difference from overclocking, i'd probably have a go at it anyway, even if it's just to make things a little more future proof.
