I'm thinking of building a DIY ViDock for my bro (he only has a laptop) for D3, but the cheapest card I see with x1 is http://www.ebay.com/itm/HIS-H545H1GD1-Radeon-HD-5450-Silence-1GB-64-bit-DDR3-PCI-Express-x1-Low-Pro-/120878493920?pt=PCC_Video_TV_Cards&hash=item1c24eb70e0#ht_3185wt_1396 which seems pricey considering I saw a x16 for $25 after rebate on newegg a month ago. Any suggestions? I could go with a pe4h but it's $40 more than the pe4l.
