I'm thinking a 1155-socket mobo, i.e. the GA-H77M-D3H, so I can overclock some time later, even if the next CPU can't overclock, the one after will (I.e. an i3-2100 now, but getting an i5-2500k in a while).
I don't need a case, or a PSU, but need Mobo, RAM, CPU, and possibly GPU (if it's worth the upgrade), a CD drive, and a 2TB HDD. A great site to use in Australia is mwave.com.au, which is what I use. Any help with getting the upgrade into the $300-450 mark would be awesome.
