In general laptops are not designed for high end gaming. As of real time strategy game >sins< will have big battles with great numbers of fleet in one view, thus making it impossible even to think that they could make the game compatible to old computers or laptops.
At the moment the most common computer in europe should be around
7600GT
1gb ram
AMD Athlon 64 3200+ or Intel Pentium D 935, 3.2Ghz LGA775
Windows XP home
Early next year the majority is using about 50% more powerful parts like mentioned above. As of you can double the computer specs in every 2 years, when developing a game.
My rig atm is :
GeForce 8800GTS 320MB GDDR3 PCI-E
800MHz DDR2 1gb+1gb
Intel Core 2 Duo E6600, 2.40 GHz, Socket 775, FSB 1066, 4MB Cache
Western Digital Caviar SE 250GB SATA II 8.9ms 7200rpm
Vista ultimate 32bit
and for eyecandy/pleasure
Samsung SyncMaster 226BW 22'' 1000:1/2MS/1680X1050
Thus a warning that samsung had some 226BW screens released with "bad" lcd screens/"firmware" , the native resolution was locked to 1600x1200, and it should be 1680x1050. but a good LCD screen tbh, i have two

Updating the computer early next year to quad core and better graphics card and to 4gb of memory.
when i buy games i intend to enjoy them, and hardware should not be an obstacle.
