If you can use the mail-in rebate, Powercolor has a 4GB 470 with a decent cooler for $150 + shipping: https://www.newegg.com/Product/Product.aspx?Item=N82E16814131705&nm_mc=AFC-C8Junction&cm_mmc=AFC-C8Junction-PCPartPicker,%20LLC-_-na-_-na-_-na&cm_sp=&AID=10446076&PID=3938566&SID=
Alternatively, if you add ~$25 to your budget you can get a 4GB 480 (again - requires using the MIR): https://www.newegg.com/Product/Product.aspx?Item=N82E16814202270&nm_mc=AFC-C8Junction&cm_mmc=AFC-C8Junction-PCPartPicker,%20LLC-_-na-_-na-_-na&cm_sp=&AID=10446076&PID=3938566&SID=
FYI both of those cards include a decent AAA gaming title too... could be worth $60+ to you if you were intending to buy a game anyway (and if the included title is something you're interested in, of course).
