No probs. Of course it all depends on how much you are willing to spend. You can get a decent machine for around £600 and an awsome machine for around £1k these days.
If it were me I would go for a 1gb (2gb preferred) Nvidia graphics card, 4gb RAM (8gb preferred).
Avoid onboard graphics like the plagueAs for processor, it is difficult to go wrong these days. AMD are just as good as Intel - it all comes down to where has the best deal. Ideally get a quad-core (or 6 if you can afford it) processor of at least 3ghz. Cache size of at least 3mb should do you here.
Lastly, get one with the main drive as a solid state (flash) drive, then you can plug in a huge storage HDD as your second drive for little cost.
Here are some links to some potentials to get an idea of what you are looking for:
A £1K PC.A £600+ PC.A £450 PC.This site also does some decent ones that are worth a look.
One more link that may be of use is
this page, which gives you a good breakdown of the differences between Intel i3, i5, i7 processors. Basically, i3 is good, i5 is very good and i7 is top-of-the-range.
If you come accross any you like the look of, post a link and I will take a look for you.
Happy hunting
