To get my BEST Gaming Performance would a 2GB Card with DDR3 Memory be better than a 1GB Card with DDR5 Memory?
The reason I was asking [as some of you point out that DDR 3 is "old hat"]
While a good point, AFAIK the Z77 is only marginally more expensive chipset with the majority of the difference being the other higher end components on the mobo. So, while most z boards are overpriced I wouldn't outright rule finding one that offers good value.If you are getting an i3 there's zero reason to get a Z77 motherboard - the i3 chips cannot be overclocked. Save the bucks and grab a B75 or H77 motherboard instead.
Not too sure why you opted for a VelociRaptor, those are definitely old technology. You would be much better off with a small SSD for boot drive (Windows + applications) and a larger slow spinner for storage.
Can't say just from this in of but a card which doesn't use gddr5 can't even use 512mb properly. So I guess 1gb with gddr5 may be better.
wide bus with low frequency memory is no better than faster memory with more narrow bus. bandwidth is bandwidth for the most part.ORLY?
You may want to reconsider that. Take a look at old 8800 GTX or HD2900 PRO. Both have gDDR3. But they have 86 and 102 GB/s memory bandwith. Compare this to this generation GPU with gDDR5 GTX650Ti which have 86 GB/s memory bandwith. Just as much as old 8800GTX with its gDDR3.
But there is more to it. 8800GTX's memory is faster than GTX650Ti's due to low freq and wide memory controller.

But, DDR3 doesn't automatically mean slow or lacking bandwidth. There are DDR3 cards that use a 512 bit bus (is 'bus' the correct term here, it's not really a bus, but more of a connection to the GPU... someone help me out here) and there are DDR5 cards that use a 128 bit, uh, bus/connection. Really what you want to look at is the total bandwidth, not what kind of memory the card has.
There are no DDR3 cards that use 512bit bus.
There are GDDR3 cardss that use 512bit bus and are good. Those are older nvidia cards which are pretty solid. At the time they decided to go with GDDR3 and double sized bus because of a lack of GDDR5 chips.
Also, you are wrong about the statement that there are good DDR3 video cards. There are good GDDR3 video cards, there has never been a good DDR3 video card. This is because DDR3 is only paired with the worst GPUs available.
Also, DDR5 does not exist. GDDR5 does. GDDR and DDR are different things and your constant confusion of the two is the source of much of the mistakes you made in your post
Current existing memory technologies with DDR in the name:
DDR1
DDR2
DDR3
GDDR1
GDDR2
GDDR3
GDDR4
GDDR5
I was talking hypothetically, as if such cards exist.

I doubt any new DDR3 cards with 512 MB memory buses are being made, let alone ones with 2 GB of memory...
Gotta love BB selling nerfed cards at above premium prices.
That's fine then. You are correct in the hypothetical, it is critical that this is clarified as a hypothetical.
"Could be done" and "exists on the market" are very different things.
At the moment the cards are only manufactures with either DDR3 (NOT G!) or GDDR5. And the DDR3 cards all suck.
The GTX280 (a fairly old card; June 17, 2008) had combined 512bit bus with GDDR3 ram btw (Since you asked earlier on).
