I have an AMD Athlon XP 2800+ CPU. Two years ago, I purchased a Nvidia GForce FX 5500 128mbs AGP Vid Card. Everthing is fine, but getting ansty about buying a new PC. This one is a Compaq Presario SR1124NX. Rather than purchase a new computer, I am wondering if I should spend a few bucks on a newer card? The CPU will stay as is, and my RAM is 1gig. Any suggestions?
