unless you have to have 512mb, the geforce 7950gt is an all-around faster card. this one is $190 after $15 rebate: http://www.newegg.com/Product/Product.aspx?Item=N82E16814130074
and, unless you have to have it now, wait about 3 weeks. nvidia will be releasing new midrange dx10 cards in april. even if they don't come down to your price point, the x1950pro and 7950gt will certainly drop quite a bit.
i was just getting my first gaming rig and was wondering if u guys think this is a good config.
