Yes, that Voodoo will be a problem. It has no T&L, it dosent have DirectX expansions, it isn't actively supported by anyone. Replace it and the rest of your machine should be adequate. A geforce4 Ti would be a good replacement, but that still not DX9 compatable, so you want one of the GeforceFX range, probably the 5200. (Which is crap, but more power will be wasted since your machine can't use it)

Or you could do a total rebuild, a couple of hundred quid and you could get a decent gaming rig.
