That sounds like a decent enough machine to me. The video card will help a lot, but I was saying in another posting, Wal-Mart just started carrying a GeForce FX5600 256 Mb card (I have one in lawaway. Oh, to dream... If CompUSA had layaway...

) for about $250. I think the Athlon 2200 is somewhere equal to a 2.4 gig Pentium, but I never could figure out how to translate AMD's numbers.
I bought my PC at Wally world and did ok. I got a 2.4 gig P4 with 512mb Ram and a 120 gig hd. I added a stick of 512 mb ram to get 1024 total, and due to some problems with the purchase (see below) ended up with an extra 60 gig hd for a total of 180 gig hd.
One thing to be sure of...
NEVER EVER, EVER, EVER buy a box that has been opened. I did and the box had been opened and someone had stolen the RAM and replaced the HD with a 60 gig. They had upgraded their computer and returned this one. I ended up dealing with Sony (It's a Vaio) and Wal-Mart on it and both were more than willing to help out. They exchanged the tower and when I explained I already had installed some programs on the HD, they let me take that one too!
Wal-Mart is really getting some decent things computer wise. I found one of those little USB keychain drives (128 mb) there for $40.00, and a DVD writer (next purchase) for around $250 also.
