Okay. Well, that was as helpful as it was confusing.
Sky: I haven't looked into every motherboard manufacturer, I prefer Gigabyte and usually just compare their offerings to Asus in order to determine which I want. Gigabyte has many motherboards available that specify they are only capable of handling 4GB of DDR2, not 8GB of DDR2. These boards are cheaper, usually by about $50 which is why I was asking.
Val: Thanks for attempting to clarify but I'm still not sure I understand. I get the fact that at some point in the future DDR3 memory will actually be cheaper than DDR2 because the manufacturers don't want to continue to produce extreme numbers of variants in memory type.
I'm more interested in performance capabilities, and as far as price goes, DDR2 is currently extremely less expensive than DDR3.
At that point, I'm left to wonder.. would I be better off two years from now with 8GB of DDR2 or 4GB of DDR3?
The difference in cost (at this time) between the two is rather large.
So large, in fact, that while I might get 8GB of DDR2 for my new system, I'd probably only get 2GB of DDR3 if I chose that direction.
What's the cost/benefit ratio? Doesn't DDR3 only provide ~30% more bandwidth?
Unless I've been looking at the wrong numbers (which is definitely possible), 8GB of DDR2 would still be superior to 4GB of DDR3.
And the price point favors 8GB of DDR2 over 4GB of DDR3.
Sorry if this is a long, drawn out silly discussion about things people should already be aware of. I appreciate everybody's contributions and patience as I work through entirely new CPU sockets, GPU interfaces, and Memory modules.
I'm really not stupid, I swear.
