I need to get a wifi adapter for my desktop pc. currently i have an older pc that still runs on windows xp, but i will be upgrading it to windows 7 soon. also i will be getting a new pc come the end of the year. I want to get a wifi adapter i can use now, but will be very fast for my new computer. I intend to be doing some online gaming with it so i want to be as lag proof as possible. Any suggestions on maybe a top of the line adapter and possibly a best bang for the buck adapter. Only because I may be able to hardwire eventually, but as of now it is impossible.
