Just a note here, ram is not the deependant factor of a graphics card, the more it has will not create a better card. This is just what the manufactures want your to think to get more money for a card when it'll perform the same.
For video editing I'd suggest the E6600 processor, while it is more you'll see a noticable difference. Wait till april 22nd, there going to be price cuts that'll be quite significant. Also you'll want a DX10 graphics card if your gaming and you'll probably want to wait a month for this because ATI is release thier products as well as the budget line of GPU's are about to be released by Nvidia.
Also, as Dryfter mentioned be sure your hard drive has no less the 16Mb as well as SATA 3.0GB/s.
