Heat sink for quad, help!

I'm literally working on deciding my last component for my computer... the heatsink I will be using for my new rig. I don't know what will fit and I'm hoping someone can point me in the right direction. I've read a bunch of posts and I think ultimately I'll convert to a watercooling system, but in the meantime I want sufficient cooling! These are the components that I think affect the heatsinks I can use:

CPU:
Intel Core 2 Quad Q9450 Yorkfield 2.66GHz 12MB L2 Cache LGA 775 95W Quad-Core Processor - Retail
http://www.newegg.com/Product/Prod [...] 6819115042 - $340

Mobo:
GIGABYTE GA-X48-DS4 LGA 775 Intel X48 ATX Intel Motherboard - Retail
http://www.newegg.com/Product/Prod [...] 6813128336 - $235

Memory:
2x OCZ Reaper HPC 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Dual Channel Kit Desktop Memory - Retail
http://www.newegg.com/Product/Prod [...] 6820227289 - $98

Case:
LIAN LI PC-65B Black Aluminum ATX Mid Tower Computer Case - Retail
http://www.newegg.com/Product/Prod [...] 6811112040 - $130

Any help is appreciated!!! Thanks!

I have just purchased a very similar setup and only have the heatsink left to buy. I've heard the Xigmatek S1283 is the one to get but I live in Australia and I can't seem to buy it anywhere.

What would be the next best cooler which I can use to overclock a little.

My setup uses the same Motherboard and CPU as the OP but my case is the Antec 900. Any help would be appreciated.

Hmm.. same question here for almost identical config (Q6600 with an Lian Li case.. also a GA-P35 mobo.)

Xigmatek seems most highly recommended, cheaper than the True and lighter too?

but does this fit the average Lian Li case? (mine is the PC-7A.. looks like the 65 mentioned in this thread)
