Windows 7: Is a 4 GB DDR3 graphics card better than a 1 GB DDR5 card?

Windows 7 Ultimate x64

I more or less play all the games that I can get my hands on. Currently playing hitman absolution and tomb raider. Not sure whether they support GPU physx. I got a bit confused after reading that Radeon 6670 doesn't support physx. Most of the games that I play shows nvidia physx during startup. So was wondering if lack of physx will hamper gameplay.

Not in the slightest. Physx is still nothing more than some fancy effects that have zero affect on gameplay. Also a GT630 won't be powerful enough to enable Physx, not unless you put all other setting to low.

No, and most games don't use PhysX, unless you want those features for say borderlands 2 which supports it. It won't matter unless you're into that. If you don't care about PhysX which not a lot games use then go amd which is a bit cheaper or if you do care then just get a nvdia equivalent of the Radeon card you were thinking of buying. I suggest going with the Radeon card, PhysX is not really worth it and a Nvdia card at the budget would be kind of weak to make it work.
