Well, the computer upgrade was a long time coming. My old 18" Acer laptop is still working beautifully, but it has reached its limit in terms of what it can play. It has enough oomph to play some newer games (eg. Amnesia Dark Descent) but stalls badly on others (even Witcher 2 would not play well enough to enjoy). It's been a great machine, considering its relatively low cost and the fact that its Vista, but it's ready to be relegated to my older game machine.
The Alienware has the guts to run pretty much anything, I'm told.
Keep them mowing blades sharp...
