If you are looking for online deals for a new gaming desktop this weekend, you might have problems finding any real buys.
I checked the following web sites today for any real deals:
I could not find any special deal that was not happening at other times this month.
You need to watch Black Friday or Cyber Monday (next Monday) deals offered by retailers. Make sure they are actually offering recent processor and graphic sets - and not last years models that are going to be cut in price at the end of the year anyway.
You may have better luck than me, but my advice is to look carefully and not be sold on slick marketing for a "deal" you can get at any other time.
One important note: I did not spend much time looking at laptop computers because I feel that laptops are poor choices for gaming (including Second Life). If you are looking for a laptop. you might have better luck.
