By how much does memory affect performance?

[Tommy B]

Is memory just a case of being a geek and saying "my memory is CAS 2 yours is 2.5" etc or does it actually dramatically affect performance???

Is getting the Gskill HZ CAS2 2GB kit really worth the extra £60 from the GeIL 2GB PC3200 Value Dual Channel Kit CAS3?

I mean does the fact that the HZ is CAS2 mean games are going to load twice as fast?

OK. Well what If I was planning on doing no overclocking.

I'm looking at upgrading to this spec by July:

Athlon 64 X2 4200+
ATI X1900XT
74GB Raptor
2GB Ram (this is what is causing me all the problems)

So is it worth spending big bucks on memory if I'm NOT OVERCLOCKING?

Well I'm getting the X1900XT and I aint paying £50 for the extra X when there's about a 20mhz difference between them!

Will I be ok with Geil value then?
