The Sapphire Radeon HD 3850 512 MB AGP 8x Graphics Card is a top rated card choice.
Only if it has the proper keying. Some 8x cards do, but many do not.
Yes, at 4x speed.
AnswerYes.Added:Sometimes! Not all AGP 1x or 2x video cards will have the same connection type as 4x or 8x cards, some older cards will not physically fit in the slot for modern motherboards.
yes
Yup.
Any 4x or 8x AGP card.
No it won't work!
The dimension 4550 motherboard supports up to 4x AGP according to spec. However, you can use an 8x AGP card as the specification is backwards compatible. It won't take advantage of 8x throughput but it should work just fine emulating 4x.
At the time of writing this (11/21/2009) it's the ATI HD4670 which is available in AGP 8x format will function perfectly fine in an AGP-4x motherboard.
Hi, I believe the GeForce FX5200 is a 128MB DDR video card and its compatible with an AGP 8x interface. Since I have the same motherboard, P4VXASD2, I know for a fact that this motherboard does not support the AGP 8x interface, and on the contrary, the FX5200 is a AGP 8x card and I am pretty sure it is not backwards compatible with AGP 4x which in fact is supported by your motherboard. If you are looking for a video card in the same/lower price range, I would recommend you to buy the ATI Radeon 9200/9200SE/9250 because they support upto a max. of 8x and they are also backwards compatible with the AGP 4x. I hope that answers your question.
Yes, However it just won't work at full speed.
