what will directX10 mean.....

Hi guys. Ive been trying to get a grasp of what DX10 will mean when it comes out. So far I understand it will be as much as 3-8 times fast than DX9c
. And I also know that it will considerably increase graphic performance and quality. But one thing im still not so sure about is whether it will be compatable with current graphics cards, for i myself am using an AGP Ti4200.
Ive also read on some threads about people waiting for DX10 before upgrading graphics cards. which made me wonder if older cards will be DX10 compatible
. I for one want to wait before I build a new rig for cost and better techno reasons
. But just so if anyone is still confused about the DX10 thi, heres a central post that will clarify those questions. thanks in advance!
