well good luck finding that for 200.. but dfi has one for 200 dollars.. or close to 200, and foxconn also has one, they are both on newegg.com
oh forgot to mention, asus also sells a mobo with sli if your interested in that.. its only about 130 or so, you should check that out on newegg as well, and its ddr standard is lower than 800, so you could go cheaper on ram too
