Zee I think CPU alone is not the solution; a very strong GPU is required( minimum 1 gig dedicated and 1.5 to 1.8 even better) and available RAM is also important as it plays a role in how fast a pc works .Minimum 4 to 8 or more.Your huge maps may be part of the reason.I play the original TvsT with minimum 18 to 20 but with your missions 1 and 6 they drop to 8 to 14 and even lower with Kursk light mission 1 (4.5 to 5.8).It;s got to do with coding and the size of your maps.You may have to scale them down may be by half and see what happens.
JHS has a good processor but his GC is only 512 mg (ATI X1800)if I am correct this explains why his fps are so low
Just a thought....
