cheapest and easiest thing to do would be to just buy a new video card. that's really the main thing holding a system like that back in games
He is going to need a new power supply for that videocard, because I can almost guarantee he is using the power supply that came with it. With my mind powers of telepathy he is using a Bestec 330 watt switching power supply with a meager 13 A on the +12v line ;) . Just did a upgrade to a similar specced HP so that is a total guess and it's probably right ;) I have encountered a few HP's where the power supply area is a non-standard small bay that a full size/longer power supply will not fit into.
But yes, I agree with soulwind, it isn't that bad of a computer, definitely the videocard in your instance is holding you back.
This is assuming I am thinking of the same case I think you have. These will be the parts you will need:
Corsair 550 watt power supplySapphire Radeon 4870Total price: Just under 370$
Yes I know the power supply is a bit 'overkill' but I am thinking future upgrade here. Once he outgrows his processor, blam he already has the power supply and videocard taken care of.
