2GB AMD Radeon HD 7730M vs 2GB NVIDIA GeForce GT630M

Neither of those are going to be any good at games really, unless your willing to drop the ingame settings way down.

what would be the ideal graphics card to get for those games?

whats ur budget and country of origin? both those cards wont game very well.

Basically just pick either a laptop or gaming, unless you spend a massive amount of money you cant have both.

this is true.

I have Del laptop with 7730M - WOT yields 30fps at FullHD, medium settings. FullHD at low settings ~70FPS, min settings - higher. Maximum settings yield 15-20fps. Main pain with this laptop - switchable graphics under windows 8. Native Dell's drivers do not show Catalyst Control Center as a result you cannot set performance profile and WOT uses build-in HD 4000 video that is 2x times slower than 7730M.
