Not too long ago the idea of a multi-GPU graphics card seemed taboo and brought about a lot of negative connotations with it.  The GeForce 7950 GX2 was the first in the modern NVIDIA/ATI era and some board partners went in other multi-GPU directions until the Radeon HD 3870 X2 was released.  We took the 3870 X2 as an answer to NVIDIA’s high end cards because the company didn’t have a single GPU that could compete with the competitions parts on its own; something of “we need answer” product.

Today’s preview of the HD 4870 X2 card from AMD proves that this time AMD was planning ahead.  Our review of the RV770-based Radeon HD 4850 and HD 4870 cards showed the new GPU architecture to be very potent indeed and NVIDIA is very scared of what the dual-GPU version, known as R700 previously, would do to its line of cards.  Today we were allowed to post a short “preview” of the card’s performance and I have to say you will likely be impressed.
