My advice when building a new system is "never wait." There will always be something right around the corner. Who cares? You could wait and save money, or you could own something worthwhile right now.
So, your best bet is:
Q6600
8800GT
2 or 4 GB RAM, depending if you use Vista64
P35 mainboard
Corsair HX PSU
Only thing I would change would be maybe going with a nvidia chipset as you mentioned gaming. If its within your budget, a 680i will do wonders in gaming. Also what did you have in mind for storage?
