Apologies if I seemed rude, it wasn't my intention. Like most people spotted I was only having a joke about not wanting to spend too much on this rig.
I was hoping for people to be able to tell me how much I would have to spend if you can see my point easyrider. Sometimes I believe the budget is defined by the requirements not vice versa, and for me this is one of those times.
It looks like the X1800XT is the one to look out for since it will run these games with few problems, especially if I can overclock it which I plan to do.
Seems like I need to look no further, thanks for all your help.
