That board actually looks very good for the price (£30 from CCL?). If you wanted to step upto a better board you'd be looking at £60+ but in return in that sort of price range you would be getting 4 DDRII slots, 800Mhz DDRII support, faster FBS support and better overlocking abilities among other things.
As for graphics cards if you MUST get a DX10 graphics card the minimum you should consider is an 8800GTS (£180). Those graphics card you linked to will play HL2 and CS:S fine but not Doom 3, and playing a DX10 game on those cards will be more painful than shooting yourself in the head lol. As for the 8500/8600, again, it's a DX10 card but it's not going to be brilliant playing DX10 games, and DX9 performance is poor - an
X1950 Pro performs better in DX9 [

It sounds like you may be in a similar situation to me... I looked at upgrading my graphics card on my P4 PC earlier in the year but it seemed a waste of money spending so much cash on a graphics card using a redundant connection (AGP). So I considered changing my motherboard and processor but thought it was silly to only do half an upgrade (so to speak), as I'd be comprising features or spending more to ensure backwards compatibility, and would only end up upgrading the older half of the system 6 months down the line anyways.
In the end I coughed up for a whole new PC. It's more than I wanted to spend but I think it was worth it and the machine will last me a good few upgrades now.
So yeah, consider how much you are going to be spending on this upgrade, and how long you are likely to use the upgraded machine for before you need to upgrade it again.
Edit (In response to your last post)
Most DX9 graphic cards are available in both AGP and PCI-E flavours. Just expect to pay slightly more for the AGP version (e.g. a X1950 Pro costs £20-40 more on AGP)
