Ubutnu is better than Linux for just casual use?
I just thought I'd clarify that Ubuntu is a distribution of Linux. Linux is the main operating system, and Ubuntu is a distribution, which is a version of Linux with slightly different features to the others (a bit like Windows: Windows is the main operating system and Windows Vista and Windows XP are versions of that operating system). Whilst Ubuntu is a very good start if you've never used Linux before, there are hundreds of other distributions and it would be worth checking if any others fit your needs better than Ubuntu.

Right, gaming should be in Windows. Although it's possible in ubuntu by using wine but I don't know how it'd perform with games.
While Wine can run a lot of things, it can't cope with anything but the very oldest of Windows games.

Do you need the 64 bit? I'd go for it anyway.
Personally I wouldn't go for 64-bit Linux at the minute. There's currently no 64-bit version of Adobe Flash Player for Linux, meaning that all Flash content on websites won't work. There are other similar problems too.

Also, would i be able/would it be worth getting my current anti virus software (McAffe) onto it? Is there anything really wrong with the protection that comes with it?
Absolutely no need for software like McAfee - it won't run on Linux anyway. Viruses are far less of a problem for Linux users anyway, but if you're concerned, you can get yourself a firewall and an anti-virus scanner.
For the firewall, there are lots of programs such as Firestarter, but personally I like Gufw for its simplicity. Basically, there is already a firewall built into Linux, but it is controlled via the terminal (equivalent to Windows' Command Prompt) and can scare new users slightly

You can add a graphical interface very easily to it by downloading Gufw from
here.
There is lots of debate over whether Linux users actually need an anti-virus. While responses are mixed, the general consensus at the minute is that there are virtually no "in the wild" Linux viruses out there that will do serious damage right now, and Linux's permission system normally stops them anyway. This means that so-called 'Linux virus scanners' basically only scan for Windows viruses, which are of course harmless on Linux, making the whole thing rather pointless. However, if you regularly share files with Windows users, it's a good idea to scan your files with something like ClamTK or AVG Free for Linux.
Combine this with secure passwords, enabling WPA or stronger encryption on your new router (plus the usuals like changing the default password for the router and stuff), keeping your system up-to-date with the Update Manager, not using the root account for all tasks, and backing up your data, and you'll be fine. TimeVault is a useful tool for backups that's being developed by Canonical, the company behind Ubuntu.
Hope that helped, and good luck with Linux
