Which of these computers is faster?

i have to computers that i want to upgrade. which is worth upgrading?

PC 1:

HP pavillion

intel celeron D 3.06ghz

760mb RAM

40gb hdd

ATI radeon 9250 PCI video card

PC 2:

Custom built

AMD Athlon XP 2400+

512mb RAM

120gb hdd

nVidia geForce 4 MX440 (i dont think i works)

i want to know which system will work better for games. i cant get a better video card for the HP and its not too impressive with the games.

the other comp has an 8x AGP slot, so that has a lot of potential. i wanted to get a new video card for it possibly. what do you think will be best for racing games? i dont want to spend more than $150.

would it be better to invest in a new system? i get a lot of emails from tigerdirect for pcs like ''celeron 3ghz, 250gb HDD, SLI ready, 500w psu, 1gb RAM, DVD burner...'' for about $550.

i know its a good deal, but i cant front that kind of cash.

Well it is the second one, but not because of the processor. The Celeron D is actually the better of the two. Everyone just looks at Celeron and Athlon and immediately says Athlon is better, they fail to notice that they are looking at a fairly old Athlon compared to a fairly new Celeron, meaning the Celeron is actually better.
