This week we have for you one excitingly interesting test about performance scaling of HD 4890 against 2x HD 4890 in CrossFire mode, with two of the most popular processors in the gaming class of Intel and AMD - Core i7 920 and Phenom II 955 BE. Expect not much talking though, we'll get straight to the tests and their results.

The release of HD 4890 was quite acclaimed in hardware websites. Reviews were mostly positive - swell performance and good price. Respectively 2x HD 4890 became one of the fastest options for AMD/ATI graphic cards fans. so we decided to determine how much of performance boost you get with two instead of one, but with two different platforms. While Core i7 has more rough power - triple channel memory, 8 threads, its processor frequency is 2.66GHz, an the price of the system i s higher (how much you will find in the conclusion), AMD Phenom II 955 BE pulls its load at frequency of 3.2GHz. Right, lets find out what exactly matters for getting more frames in your games.
