I have a PC thats about 3 years old. When I purchase it I was unfortunately unaware that it had intergrated graphics. The motherboard has PCI slots (3) and I have recently been browsing ebay for video card.
However, when I look at the pictures the cards listed as PCI card look like they are AGP with three teeth instead of the 2 on the PCI slot; one long one and one short one.
Do all PCI cards look the same phsically or do some have 2 teeth while other have 3 teeth (I don't know what else to call them. By teeth I mean the actual tabs you fit into the slots).
I recently purchased RAM bringing my system upto 768 MB. I want to play games but I need something that supports pixel and vertex shaders. I don't expect super performance and not expecting games like Half-Life 2 or Doom to run. I can live with 30 fps on simpler games but they require the vertex-pixel thing I mentioned.
Anyway, yeah is there a difference physically with the different makes of PCI (teeth). Also, when I was looking up PCI cards the description read support for 2x or 4x agp. ow does a PCI card support AGP? Sorry if I sound really stupid. I am new to all of this. Thank you for your time, I really appreciate it.
