Now with all the B3 stepping goodness.
For testing the ECS H61H2-A I have used an Intel Core i7-2600K, Kingston HyperX 4GB DDR3-2133 ram, Zotac GTX 580 AMP! Edition graphics card and a Western Digital VelociRaptor 300GB HDD with Windows 7 Ultimate. All of this is powered by a Cooler Master 1200W Silent Pro Gold PSU. For comparisons I have used our resident testbed Gigabyte P67A-UD7 ($330) and the recently reviewed ECS H61H2-A ($70) motherboard.
In terms of raw performance, you’re not losing out by much on CPU side as seen from 7-zip (multicore), WinRAR (single-core) and Cinebench R11.5 (multicore). On the gaming side, the performance seems equal across the board, so both the i7-2600K and the GTX 580 are being used to their maximum potential.
In my opinion the ECS H61H2-M beats out the H61H2-A due to two major factors: USB 3.0 and Dual channel DDR3 ram on 4 slots. The ECS H61H2-M has a small form factor, extremely competitive performance, and some nice basic features. Yes, there are no extra frills on the side, mainly no SATA III or CPU overclocking capability, but that’s a limitation of the H61 platform itself. For a decent HTPC or even a gaming rig with a limited budget in mind, the ECS H61H2-M is as good as it gets.
