Will this computer (http://www.newegg.com/Product/Product.aspx?Item=N82E16883103924) be able to work with this GPU (http://www.newegg.com/Product/Product.aspx?Item=N82E16814487024)? I'm pretty sure that it will fit in my case and that it'll work with most of my hardware, but will it work with my PSU? I know that my current power supply is pretty wimpy. Thanks for any answers
