If you have the budget... a low-medium spec barebones PC (I'm assuming this is a tower?) with a Core i5 and 4GB of RAM with a dedicated (but nothing top end) video card would be the way to go if IL-2 1946 is your only gaming need. You can sometimes find these for $350-$450ish. Barebones... so assuming you already have keyboard/mouse/monitor/etc. and just need a tower to plug it all in to. Save some money that way
