I have 3 Toshiba Satellite laptops w/ very fast processors and plenty of memory...
I have 1 HP laptop and 1 Dell, all with Win7 or Win8, fast processors and more than enough memory...
I have a very fast HP desktop w/ Win7 along with a few others not hooked up...
I have tried all of them with good video cards and a gaming mouse, and the PC I play on and that plays the game the best is a old Dell Desktop with WinXP on it and a Pentium 4, 3.1gig processor, 3 gigs of Ram....
You might want to go backwards instead of forward....
