One of the first HD 3870 X2's to be unveiled is from Asus, and the board is straight away a little different from the rest. Detailed here, Asus has equipped the board with a custom dual-fan cooler, and four DVI ports. Previously, Unika was the only partner to unveil a dual-fan HD 3870 X2. Like the recently announced Striker II Formula motherboard, Asus has bundled Company of Heroes: Opposing Fronts with the board. 1GB of DRR3 0.8ns memory is also included.
Both Fudzilla and VR-Zone have heard similar reasons as to why the HD 3870 X2 was delayed from January 23rd to the 28th. Apparently the drivers are the issue (surprise surprise!). The sample drivers that were sent to the reviewers, and are included with the bundled CD, apparently have very poor performance in games including Crysis. VR-Zone have just added another story stating that driver version 8.45 v1.3 will resolve the issue, and will be out before the 28th.
Nvidia's upcoming midrange board - the 9600 GT - was originally slated for launch on February 14th to take over the 8800 GS' duties in fighting the HD 3850. Instead however, the board has been delayed until February 21st, according to Expreview. The reason behind this is apparently due to voltage offset issues, which are experienced "during certain applications". The site note that Nvidia needs some more time to fix the bug.
The Radeon HD 3870 X2 may have been delayed another week, though that hasn't stopped its slower counterparts from rolling out the door. Although only boards based on the HD 3650 and 3450 have been announced, we've included the specs of every board in the series in the table on the right (including the unconfirmed Radeon HD 3690). The Radeon HD 3450, 3470 and 3650 are already available, and they all cost under US $100.
