So right now I am typing this on my 2008 Macbook aluminum. It's great and all for school and work but my real computer, is the one I built on my own my 3570k, 660ti machine. It runs any game on max that I have thrown at it with little to no lag problems. My actual issue is that my laptop has great Wifi download speeds but my tower is snail slow with a direct ethernet connection to my router. When I try streaming video, it lags and freezes like a netbook running Crisis but runs near smooth 720p on my Macbook. When I download games it has 800kb down and uploads, well I don't really upload much of anything; so I cant comment on that. So what do you guys think I should do? I'm not all that great with network settings but I'm thinking about buying a USB network adapter for my tower, instead of running it through ethernet. The ethernet cable is running a long distance from where my router is if that makes any difference. Thank you for any help you can provide!
