Yes, you still need paging files. Generally 2GB is the most you'd want, but it's safe to let your OS handle it if it can do that sort of thing.

PS: Having upgraded from the machine Mavro HAD to the machine he now HAS (except I have an NV7800GT and the ASUS A8N-SLI), I have to say, there is no comparison. If you try and run Fear on the rig he used to have, good luck to you.
