Which mini displayport to vga adapter to buy

[katoho]

Hi everyone,i bought an hd7950 but its dvi port is defective and only hdmi and mini displayport work but my monitor only has a vga in.My question is can i use a mini displayport to vga adapter and use it as my only display?If it is possible which mini displayport to vga adapter should i buy? Will any adapter for apple devices work or will i need a windows specific one?what about active and passive adapters,i heard you only need them to connect more than 2 displays.I decided against hdmi to vga adapter as i think hdmi to vga adapters only output at fixed 16:9 resolutions like 720p,1080p etc and my monitor resolution is 1680x1050 .I'd prefer not to spend a high amount on this adapter as i'll probably upgrade my monitor soon .Help me out guys really need your help and thanks in advance
