Setting up dual monitors.?

I am trying to setup dual monitors but not sure which cable to order. I have 2 monitors and one has only a vga input the other has both a vga and a dvi input. Problem is my computer only has 1 dvi input, and hdmi input and a dvi input. I have a vga dvi adapter, so that takes care of one screen. My question is can I have dual screens with one extended display over both if I buy a hdmi to vga converter cable?(http://compare.ebay.com/like/280601177861?rvr_id=196400839105&tm_kw=HDMI+to+VGA+cable&crlp=7312889490_1439982&MT_ID=1040&tm_kw_mt=68538882_1041&tt_encode=raw&keyword=i280601177861::new+gold+male+hdmi+to+vga+cable+6+ft+hdtv&geo_id=1&adgroup_id=2302942410)

I have: ati radeon HD 5570 graphics card. I went on their site and couldn't tell if it supported dual monitors or not.

Yes the 5570 supports dual monitors. If you use a DVI->VGA converter you'll be fine.
