I'm just looking to upgrade and don't really know where to go with memory, I had some dominator ddr2 in my current setup but I've read that the difference in real world performance of ddr3 1066/1333/1600 can be very minimal.
I'm swaying towards the XMS3 and have no 1066 avaliable from the site I'm buying from.
Its to go on a ASUS P8P67 Pro with a 2500k. Am I right in thinking that 4gb should be ok for general use and gaming for now (I have 4gb in my current).
Also I've got a ASUS 6950 direct cuII (3 slot) card and I'm planning on either getting the same card to Xfire (if it will fit!!) or another 6950/6970 later.
Any advise on the memory primarily but any of the set up will be greatly appreciated as this is only my second build.
Oh yeah I plan to keep my current case but will probably get a Corsair 600t SE later.
'Cost Effective' is an ambiguous term itself, so based upon what you listed I'd try to make the 'Sensible' choices.
That said, the Sandy Bridge's 'sweet-spot' for gaming is 1600 MHz CAS 8/9 with 1.50v; IMO I prefer the 1600 CAS 8 and again with Gaming on my mind a 2x4GB with Window 7 x64.
Cost Effective for various uses, the 1866+ MHz is best for Multi-Tasking so here's a side-by-side -> http://www.newegg.com/Product/Productcompare.aspx?Submi...|20-231-445^20-231-445-TS%2C20-233-144^20-233-144-TS%2C20-145-345^20-145-345-TS%2C20-231-455^20-231-455-TS%2C20-233-170^20-233-170-TS
