SSD will result in quicker boot times but tend to have a small capacity so you will end up with games installed on another hard drive anyway, particularly if you have lots of them.
Anything over 6mb of RAM will work fine. Equally an i5 processor will work okay as most of the work is done by the graphics card. I went for an NVIDIA GTX770 with 2mb of RAM, i5 processor and 8Gb of RAM and that is running recent games at full resolution in highest settings without difficulty on a 24 inch monitor. If you have a bigger monitor then you will need a better graphics card or settle for lower settings. It is running Windows 8.1 with no problems apart from one older game.
Anything above those specs will keep you entertained for a good while.
I understand that Alien ware are good but you are paying for the name somewhat. I bought off these guys,
DinoPC but they are not much use to you with your given location.
