Video cards?

I have bought a ECS Elitegroup motherboard with a NVIDIA GeForce 7050PV/NVIDIA nForce 630a video card embedded into the motherboard.



At a local store there is a Diamond ATI Radeon HD 3450 PCI-E Graphics card with 512 MB memory in it.



I am going to be playing pc games, is it worth it to buy the new graphics card or stick to the embedded one?|||It all depends on how serious you are about gaming, the already embedded one is fine with playing regular PC games but it's nothing compared to todays high definition games running on Directx10, check for more updated cards|||Is there a PCI-E x16 slot on that board? I'd get a 9600GT or something like that instead of the 3450
