ATI Radeon HD 4770 CrossFireX Review
 

We have always claimed and continue to do so that contemporary multi-GPU concept has a number of fundamental issues, some of which cannot be solved, at least not with where the corresponding technologies are today. Nevertheless, if homogeneous multi-GPU systems haven’t yet reached ultimate perfection, then they are at least extremely close to it already. Most newly emerged compatibility issues with the new gaming titles are being solved very quickly and the drawbacks that could be eliminated completed are long gone.

In the times of economic crisis when many gamers can’t afford to spend a lot of money on graphics cards, the value of compromise solutions increases dramatically. Multi-GPU systems built out of inexpensive mainstream graphics accelerators also belong to these solutions. We have already discussed several systems like that including Nvidia GeForce GTS 250 SLI, Radeon HD 4830 CrossFireX and Radeon HD 4670 CrossFireX. The first two demonstrated pretty decent potential, while the latter turned out too slow and didn’t prove up to our expectations: it failed to compete successfully against single-processor Radeon HD 4870 and GeForce GTX 260 Core 216.
