Motherboard for Linux/RAM Advice

Further to the thread http://forums.hexus.net/hexus-hardwa...se-advice.html, I've decided on the Antec NSK 4000 - http://www.scan.co.uk/Products/Antec...U-Black-Silver

I 'may' (God willing) have a play with Linux and I hear ATI drivers aren't too good for Linux. (The motherboard I was previously thinking of was Gigabyte-GA-MA74GM-S2-AMD-740G-S)

As I've changed the case, I can consider for ATX motherboards as well.

Should I stick with the Gigabyte 740G or go for a nVidia 8200 (8300 are too expensive IMO)?

Also, please can someone advise which RAM to get? Would prefer 2 x 2GB sticks.

Thank you.
