Look here for all the best deals about, proberly worth saving a bit more, for £40-£50 your looking at either the ATI 9200:click here and FX 5200:click here which are both better than the 9200se that you have but niether will run the current crop of games smooth without detail and quality levels at low settings.
Would definatly recommend hitting the bank balance for another £20-£30 and look at the FX 5600:click here or Radeon 9600Pro:click here
which will be a Big improvement over what you have, but unfortunatley even these wont run the latest stuff with all settings on high with no slow down, but I think medium settings will show a great level of visuals and playability.
These cards although more expensive kiss ass, for a great price:
As to having a standard 9200, it's not DirectX 9 enabled, so it's not what I realy want.
All the other cards I'd like to have but I'm realy trying to keep to a budget(my other half's not very happy I've even suggested I want "something else" for my "damned" pc ;-) ).
Why I'm considering the 9550 is that its DirectX 9 enabled(being an under clocked 9600 at heart)and I can get one delivered for just over £50. (Because this is such a good price for this card, I've even double checked with the supplier to make sure it's not the 9550SE, and it isn't).
