Hi,I really need help here. I recently was handed down an old dell studio XPS 435 MT. The video card is shot and the OS needs updating to windows 7. I am running 64 bit with an i7 processor. I'm hopeing to be able to run the PMDG 737 ngx with full scenery with at least reasonable graphics. And i have a budget for the card at $200 (unless impossible) as i need to get windows 7 as well.Thanks

here's a possibility: http://www.newegg.com/Product/Product.aspx?Item=N82E16814133341&Tpk=gtx470
