Acer Predator G5910

I got this when it was on sale (200 off).

After upgrading from an old pc and not knowing much about computers this was recommended to me by one of the pc engineers at work after giving the the recommended specs for playing guild wars 2. I play LOTRO and have always had lag/slows/etc in PvP...

everything was great but according to the details on amazon it says come with vga outlet but it only comes with hdmi and dvi so i had to buy a new monitor to use it,and at the moment i can only find 500 gb of hard drive not 1tb
