I have a razer Death adder black already.
Yes, I'll be buying 2 x 4GB RAMs.
About wifi adapter, What is the difference between these USB ones and the internal ones that comes with 3 antennas?

Also will there be a difference in the game I play when I install it in SSD and HDD ? Apart from the loading time ? Also the loading time will be ~30-60 secs in a 7200rpm HDD right ? I don't want to load all the games in the SSD because I'm buying a 120GB and apart from OS and work data I'll have ~80GB and 4-5 games will fill that up. [/b]
Okay then that is covered, where are you getting the Vespula so cheap?
The USB ones are just receiver units, same as the PCI card you have found on eBay. With the PCI card the only advantage seem the MIMO antennas though I am not really confident in them changing the game. Suggest that you go for a USB adapter the performance will be at par. Take a reputable brand which will help in easing any after-sales issues.
Only disadvantage will be the loading times when you will have the game on the HDD, rest the system should carry on fine.
Hope this helps, Cheerio!
