What do you mean by sacrifice in performance? I thought mATX was simply just a smaller ATX board with less lanes and stuff like that.?
Well, you pretty much nailed it. You have less expansion slots to work with, so nice setups like Tri-SLI and such aren't going to work. Additionally, since mATX boards come with at most four slots, and since all gaming GPUs are dual slots, if you go with an SLI/X-Fire setup, you won't have any room for any other expansion cards (sound card, wifi card, etc.). So it's not so much a sacrifice of performance as it is less headroom for performance upgrades/setups?
But beyond that, you shouldn't see any performance decrease from similar setups. That is, an i7 920 @ 4.0 GHz with a GTX 580 should have the same performance on an ATX board as it does on an mATX board.
Agreed, but even though most mATX boards run multi-GPU setups at 8x/8x, there's very little real-world performance drops. You'll notice your benchmarks dropping a bit at 8x/8x, but truthfully your games will look unchanged.
The SATA connectors I agree with, but even then most mATX cases I've seen don't allow for more than 2 3.5" drives. So unless you get creative with mounting, you'll also be limited by your case there. RAM slots used to be an issue with S775/AM2, but with the latest boards in S1366/S1156/AM3, mATX boards became very performance-oriented and have great OCing headroom and the usual amount of RAM slots.
And I definitely recommend those suggestions. Great performance mATX boards
That Asus specifically is one great monster who I think is probably better than most ATX boards out there.Edited by r31ncarnat3d - 3/2/11 at 9:55am
