Hi Guys, Need some advice here. Have finally decided to pull the trigger on a graphics card. I am an very infrequent gamer at this point in my life... but do use video editing, photoshop etc. I am looking at this as a prospect: http://www.newegg.com/Product/Produ...4150464&cm_re=5770_xfx-_-14-150-464-_-Product Any reason I should look at either a 4870 or a 58xx card? Thanks!
