Re: System help for Optimal RTW Carnage!
And having a stuff-off-shovel PC won't actually help with the older RTW anyway as it doesn't take advantage of multi-cores, top end gfx etc. It's an old game but even so, unless you have a really ancient PC it shouldn't be playing at lowest unit levels.
Still, as Irishron says, buy a PC for what you can play now, not what you may be able to play in the future, just buy something that can be upgraded. Your best bet, give the actual budget you have and what your current specs are, you may have bits that don't need upgrading and then you can spend more money on other components.
