So I've got a Dell Vostro 220S (slim tower) which I was using at work that I'm now using at home. It's running Windows 7 Professional 32 bit and the PSU is 250watt. I'm mainly just looking for a card so I can have dual extended monitors, but I'm having difficulty determining whether or not a card will fit in my case. Could anyone please recommend a card(s) for me? My budget is $100 but around $50 would be ideal.
