The X700 should, (keyword: should) be able to outperform the 6200, on paper that is. Though since we're talking here about an integrated one, the performance should suffer, quite a lot. I'd agree with the other guy, try benching out the two and keep the one with the higher score. Though if you have less than 1GB of RAM it would make you think twice about the X700, since it's 64/128/256mb (whichever you set) that you could have used for your applications.
