Now, I'm looking at a gaming PC, and since I can get the same items cheaper in person, will most likely be putting it together myself, which means lots of shots of our decisions

My wants:
Quad core compatible motherboard, for the future. I'm leaning towards the lowest costing i7 cpu (Intel Core i7 920 Processor LGA1366 2.66GHz 8MB Cache CPU) which will cost me $441 AUD.

I can't go get the Core2Quad and have it compatible to upgrade in the future can I?

Multiple hard drives

2 of Seagate SATAII NCQ 1.5TB 7200RPM 32mb Cache for $197 AUD each
However many other I can throw in, but not sure of what RAID format or anything to set it up.

Graphics card, preferably an Nvidea, as I've always had them
Also hopefully DDR3 ram.


Of course, everything outside of the case is open to advice from you guys, so tell me, where should I go?
