I just got DBPro in the mail yesterday

, but when I tried out some of the examples I noticed that the text and some of the textures were all messed up while in 3D mode, but worked fine while no 3D stuff is present. I did not have this problem in DBC. I have not upgraded to patch 4 yet, and I'm planning to buy a video card off of eBay soon. Would either of those options help? Or is there something else I could try? Thanks in advance.

P.S. Here are my current specs (they're a bit embarrasing

):
Pentium III 500 Mhz
128 MB RAM
20 GB Hard Drive (7GB Left)
Windows 98SE
Onboard Video and Sound (no other info)
