Thanks everybody for helping me out in choosing a PC. I ordered a XPS from the Outlet store and will have to add more memory once I get the PC; it is an Intel i7 with a 256GB SSD + SATA drive. Unfortunately, I did not get much of a deal because I needed it soon and could not wait for a better sale to come around.

But I really want to thank everybody who patiently helped me with information and tips.
