Nice sigs,but most of them are way too big to be used here.

The maximum total size of the sigs should be less than 70kb.

Thanks by the way.

Depends on what resolution you are playing.
Come to think of it, you are using a 3 years old CPU...(just came back from work so a bit dizzy)
However, wait until the game is release if you want to upgrade.
Here's a quite similar GPU review of your Radeon HD4890. GPU only.

Back to topic, after testing the game, I somehow find SC is now lackluster compare to its identical twin...the one with 40k in its name...
