i dont think the battle map will even load with integrated intel graphics, or if it does i reckon less than 5 frame per second, even that is being optimistic ;/

Take Red Harvests advice, and do NOT get a 5200 or any MX series Geforce4!!!

To be honest, i havent much looked into the use of directX 9 features in RTW. If it is going to be using directX9 features, and you want to see the extra eye candy get nothing less than a ATI 9600pro (do NOT get ANY GeforceFX series of cards if you plan to use Dx9 effects) ... otherwise, get a Geforece 4 4200ti 128mb or above for Dx8 play , or any Geforce FX card over a 5600ULTRA , or ATI card over a 9600pro.

Sadly, a celeron with its castrated cache will struggle with the computations necessary for large scale battles in RTW, and i think 1gb RAM will be essential for stutter free gameplay. But.. i havent been following RTW very closely as of yet (it will come round quicker that way ;) ) ... so am not entirely sure of the requirments needed for "good" gameplay (usually doubling the minimum specs given will give a nice level of play.. but we shall see).

I reccomend ANYONE who is thinking of upgrading for RTW to make a thread in The Apothecary and let us make sure you are getting the right kit
