Thanks for the response shovenose. Everything looks pretty good although the 1GB graphics seems overkill for me. Would 512Mb be sufficient?
Here's a HD 5750 with 512MB. It's $5 cheaper than the 1GB version.http://www.newegg.com/Product/Product.aspx?Item=N82E16814131331&cm_re=HD_5750-_-14-131-331-_-Product
Generally speaking you can get away with a 512MB card for a 1680 x 1050 (or lower) resolution monitor, which you have.
