Looking for a new motherboard. Need Help

Hey all,

My motherboard on my desktop just recently kicked the bucket, so, I see this as a time to upgrade from the terrible one that came in my computer.

Here is a link to my computers tech specs (according to CNET):

My main concerns are:

-Support for up to 16 gigabytes of RAM

-Possibly support for a dual SLI link for graphics cards.

I am mostly unsure of compatability issues. Also, I can't spend over $200

Any help would be appreciated.

Lots of features, 2 PCI Express 3.0 x 16 slots, supports 32GB RAM at 2800MHz, overclockable.  Only $135.  I'd recommend this one the most.

Upgraded version of the previous.  Main thing I notice is a slightly different heatsink and the addition of a single PCI Express 2.0 x 4 slot alongside the 2 PCI Express 3.0 x 16 slots.  Little more expensive at $160.

Most expensive board of the three at $210.  Has a lot of overclocking features, supports up to 32GB of RAM up to 2800MHz, 2 PCI Express 3.0 x 16 slots.  Also has 4 SATA 6GB/s slots and 2 SATA 3GB/s slots as well as support for raid 0, 1, 5, and 10.  In addition, it has 4 USB 3.0 slots and 4 USB 2.0 slots, as well as several several fan connector slots and support for ASUS fan controller software.  Basically it's loaded like crazy, but it's pretty expensive.

Overall, I'd recommend the ASRock Z77 Extreme4 (the first one) because it should have more than enough features and expansion slots for you.  At $135 you can't get much better for the price.  I'm not an expert on motherboards, so definitely go asking around for suggestions from more experienced people, but I'm still confident in suggesting these boards.
