Looking up the HP a1740n on their website, I find this page of specs: HP a1740n Spec List

You were faster than me [] I see that the HP system has plenty of free expension slots, so a dedicated graphics cars shouldn't be a problem.

Here's a ATI Radeon chipset that would probably work and is only $15 after a mail-in rebate:http://www.newegg.com/Product/Product.aspx?Item=N82E16814127544. Or here's another GeForce chipset that's the same price after rebate:http://www.newegg.com/Product/Product.aspx?Item=N82E16814130536.

Those are the kind of which I was talking about. Low budget, but they do their job nicely.

Otherwise if you feel it might be time for a new computer, just about any current computer (perhaps excluding some netbooks) should have no trouble with 1080p.

Correct. With the current developments, you can buy a fast CPU with a dedicated integrated graphics chip in it!(even faster than onboard graphics!) However it's not really 15 dollar cheap [A] But it's a good thing to look forward to when you are ready to upgrade your pc.
