Connecting 3 monitors on ATI HD 5450, whats the best way?

Hi,
I currently have 2 monitors connected to my xfx ATI 5450 (has 3 ports: 1 DVI, 1 VGA and 1 HDMI however the box says it also supports displayPort so i presume that the HDMI is also the DP). I am currently using a vga and dvi port on this card and would like to connect another vga monitor.
I currently have 1 VGA female to DVI male converter. Would i be able to set it up as such:
1 DVI male from HD monitor going to DVI port in card
1 VGA male from monitor going to VGA port in card
1 VGA male converted to DVI which is then plugged into another converter from DVI to HDMI which is then plugged in the HDMI port in the card.

If this wont work what are my options?

Hello Rezelute

An old post, if not resolved here is my solution

I bought from Ebay an USB Graphic card. Basically, you plug it in your usb port and it work. For me, a bit slower, but for text it is perfect.

Good luck
