SLI Motherboard?

[LQ4594]

Hi there! I'm looking to purchase a SLI motherboard in the future and was wondering if anyone can help me choose or recommend a great one thats also not too expensive. I'm hoping to spend less than 250 and my specs are as follow

AMD Phenom II X4 840 at 3.2 Mhz
Galaxy Gtx 570
Ultra X4 1050 watt power supply
8 gigs of ram
GIGABYTE GA-M68MT-S2P mobo
Thermaltake V3 Black edition case
with 2 extra fans

Here are 2 lists of good mobos that will suit your needs and lay within the budget.
Although you haven't specified the make and model of your RAM. You can still check out the specifics of the mobos listed here

Depending on the peripherals you want to connect later on and stuff like that, also for a further upgrade to the BD series and beyond of processors these models have been listed.
I would personally go for the Sabertooth or in general Asus, MSI or Gigabyte boards. In order of preference.

ASUS Sabertooth is an amazing board. Ona side note though, if you go SLI GTX570, your CPU will bottleneck them like you wouldn't beleive. Even a X4 980 bottlenecks tw 6950s. I'd go for an FX-8150 if I were you.
