When i play games on my laptop it usually runs from 70C - 75C and my wireless card (PCMIA) overheats, i must use wireless because my other computer uses the only wired ethernet i have in my room, and i have a USB 1.0 port on my laptop, if i buy one of those external USB wireless thingeys will it be slower because i have a usb 1.0 not 2.0?
