Thanks for reading, your assistance is much appreciated! Buying this PSU and GPU...
GPU: Gigabyte Nvidia gtx 670 http://www.newegg.com/Product/Product.aspx?Item=N82E16814125423
PSU: Antec 750W High Current Gamer Series http://www.newegg.com/Product/Product.aspx?Item=N82E16817371049
...to add onto my old setup listed below. Goal is to play Witcher 2 on highest settings. I think CPU will hold up fine. Might get 4 gbs of ddr2 ram to add onto build-- not sure more ram is necessary though. Mostly concerned with my mobo as I know it will bottleneck performance of gpu somewhat, but unsure as to what degree (PCI Express 2.0).
