Wow damn. I suppose it IS crossfire when you put it like that. I've always thought of it as just 1 single card though. Anyway anyway games are handling Crossfire better now along with SLI, I know someone who has put 2 4870x2's in his PC and it runs anything like a dream. Downside is that 4870x2's are still quite expensive. £300 region. Yeouch.
That's true, support for multi-GPU has improved a lot over the last year or so, but it's still far from perfect and given the cost of the 4870X2 the performance gain for resolutions up to and including 1920x1200 is hardly noticeable.
Check the following links from [H]ardOCP for comparisons on a few recent games.
Basically if you're not using a 30 inch screen with a 2560x1600 resolution, you generally won't need that 4870X2. =)

In fact, the HD4890 he already has is often among the best choices up to 1920x1200.

Cheers guys, so 4 gigs of ram is advisable, and perhaps a dual gpu, but if I overclocked the cpu would it still be worth changing it to a quad for gaming?
That depends, at 3.1GHz it certainly isn't bad, but to "future proof" your PC a bit ahead of better support for multi-core processing that X4 isn't a bad choice. The additional ram is a great investment though.
