Question about Cas timings

[Fern2899]

I'm not a pc hardware pro, is there really a noticeable difference between say 1600 ddr3 w/ Cas 7 latency vs same ram but being Cas 8 or even a Cas 8 vs Cas 9? Is it even worth the cost or is it mainly for bragging rights... Reason I'm asking is cause I'm planning on purchasing 8gigs (2x4) ddr3 1600mhz ram and as I'm reading I see different latency types... And I mean almost $50 price difference from Cas 9 and cas7... Now is it really that much of a noticeable difference that's it's worth paying almost $50 more?

No noticeable difference but measurable.

Measurable only with synthetic benchmarks. Get whatever ram you want.
