Maybe someone can tell us all about what theyve learned about the differences in the two GPU producers? To bad they never have any hands on experience with the items shown, that might actually help and thats not really Jennys MO.

Be aware!
The link shows a PCI Express x16 (2.0v)not AGP Video Card. Ben must be sleepy when posting up.

Shouldn't these cards be a lot cheaper by now?

This is a PCI-E card, NOT AGP!

Someone school me. What's the difference in a $64 1G card and a $250 1G card?

Memory size determines the number of pixels and the number of colors per pixel that the card can manage. Adding extra memory also adds space for buffering textures and stuff.

The real difference between a $64 card and a $250 card is the speed of the graphics processing unit (GPU) and the number of pipelines on the card. Go look at Tom's Hardware graphics charts for a comparison of modern video card capabilities.

Adding to #6 comments... The size of the memory can be misleading. On some cards, it may be cheaper to add more memory, but it's never utilized because of other bottlenecks on the card. The customer sees 1gig of memory, but doesn't realize another card with only 384mb memory actually performs better.

yeah... I thought AGP topped out at the 6600s

They still make AGP cards??

dont do it.. just wait till BF

#5 - 1GB onboard RAM really is not the defining factor in Video Card Speed. I'm thinking, in the past it used to be the most defining factor because the RAM used to be the bottleneck (back in the 8MB-128MB RAM range), thus the idea that, more RAM = faster was ingrained into peoples' minds.

Now that we have surpassed the 256MB RAM range (on the video card), that is no longer the bottleneck so you have to look at the other features of the card. The marketing departments are aware of this and are playing this card to make their sales, and I'm pretty sure it is working.

#5 Size of memory is most always is playing on the "wow factor" of marketing.

The first factor is the basic chip architecture, that includes the texture shaders and other particulars built in the silicon. Next and as important is the memory bandwidth, the speed at which the chip can access the memory. Although, M-Bw is determined by size of the memory bus (bit); basiclly the lanes of the highway, which is multiplied by the speed at which the memory is clocked. The more bandwidth translate into handling higher resolutions and high levels of AA and AF offer huge benefits if you intend to game.

Below is another post explaining more on the subject of overall bandwidth. What I find amazing is who's the first person for both forms and on both just running at the mouth. It's actually sad that he* really is a vinyl punching clown and doesn't see it.
