X700 is not the problem, it's the SE at the end of the name, which usually means in ATI terms, 64 bit memory (instead of 128 Bit or 256 bit...). So it should be pretty slow, but probably faster than a Geforce 4 TI or Radeon 8500, plus you have Direct X 9 features such as shader 2.0.
EDIT: You know what, I've looked, and surprise, it's 128bit memory interface, so you're ok (just that it's GDD2, not GDDR3). It should be a midrange performing card, but of 2004.
Here's a nice review: http://babelfish.altavista.com/babelfish/urltrurl?lp=zh_en&trurl=http%3a%2f%2fwww.hkepc.com%2fhwdb%2fx700se-3.htm
Hmmm.... Maybe not mid range performance, but OK none the less.
