DDR3 on AGP Card?

I'm trying to buy a second hand graphics card (such as X1650) and I see that some have 512MB DDR2 whilst others have 256MB DDR3.

I have read that DDR3 graphics memory is not much of an advantage on an AGP card because of limitations in the interface but on PCI-E it makes a big difference.

Is this correct?

Does OC have a 'Classifieds' forum? - can't see one.

Thanks for the update. Thought that would be the case.

I'm trying to buy a graphics card, to replace a Radeon 9700 Pro, nothing too special, around the £30 to £40 mark.

Something like X1650 Pro or XT, 6800 GT, 7600 GT, 2600 Pro.

So looking 2nd hand and pretty much restricted to the famous auction site. Trouble is the people that post there often use stock library data or pictures and are mixing up the models, picture shows an AGP whereas the text suggests a PCI-E etc. More confusing is that they tend to mix up DDR2 and DDR3 references so it's quite hard to work out what they are actually selling.

A good purchase for me would be a X1650 Pro 256MB DDR3 - just need to find a seller who knows what he is talking about or bother to answer queries.

Yep that's what I have decided.

Thing that puzzles me with X1650 cards is that I've seen a lot for auction claiming to be DDR3 and this is partly backed up by manufacturer website, and I had assumed that the DDR2 ones are older designs.

But all the ones I've seen being sold by retailers new (including here) have been DDR2 types.

Almost bought one from a large computer retailer.

Website advertises Sapphire X1650 512MB and on the overview specifies DDR3 memory.

Just about to hit 'Buy It' when I spotted a 'Detailed Specs' tab. Opened this and low and behold it specifies DDR2 memory.

So I rang their technical presales to clarify and this is the answer I got

"Ah, I been asked about this before. Basically, it is fitted with DDR2 on board but this card has the ability to share the memory on your motherboard and when it does this it becomes DDR3. That is why the webiste specification lists it as being both DDR2 and DDR3".

Sorry I wasn't being serious. I knew it was pure BS but thought I'd share what they said with the forum.
