crossfire or new graphics card?

I wouldn’t entirely agree with this, as I have tested two 5770’s in X-fire, and they matched the performance of a single 5870. I didn’t have a lot of time to do this, but they scored slightly higher than the 5870 in 3DMark Vantage and Metro 2033, and in Metro 2033 the fps was exactly double that of a single 5770 (with the same settings). The tests were performed on the same system, hence the time issue. Two 5750's should match a 5850, but have 2GB of memory.

My advice to the potential purchaser was the same, though – rather go with a less complicated single card than the X-fire setup, since it doesn’t always work as designed. If funds are limited, and you have access to a second 5750 at a good price, it is a viable option (just not in CoD at the moment!).
