Newegg has the Intel i5 750 quad core with biostar p55 chipset board for $305. For ram, corsair, crucial, kingston, pny, or pqi ddr3 in 1333 or 1600 will work fine. Ram prices keep rising. Last I checked it was about $120 for 2x2gb kits. If warranty for asus or a particular brand is covered by your vender, then you can use whatever you like. I use msi or biostar.
