Thanks very much for the helpful reply.
I have a few more questions, firstly what is it about the motherboard which determines the processor it can accept, secondly would the motherboard you suggested support the latest speeds of DDR2/3(are they up to 3 yet) as I am looking to save for a while and go all out

. Thank you.
::EDIT:: A few more questions came to mind,
What is required when upgrading mobo/processor and RAM apart from the physical side of things, do I need to do anything software wise?
Also, is Vista worth the upgrade and which version should I try for?
Very nice system meat_helmet!
One last thing haha, Would this be cheaper than buying a new processor, mobo and 4 gb of DDR2 RAM
eBay Australia: BRAND NEW INTEL CORE 2 QUAD Q6600 / 320 GB/ 4 GB RAM (item 230146276612, end time 05-Jul-07 07:16:58 AEST)
I would throw in my current geforce 7900 GTX and use that if I bought it.
