Building a new system, need your help/input

[Dr_s99]

Hi everyone,
I'm trying to build a high-end system and here is the spec. I got so far:

TYAN S2915WA2NRF-E SSI / Extended ATX Server Motherboard

2x AMD Opteron 2350 2.0GHz Socket F 75W Processor

2x Kingston 4GB(2 x 2GB) 240-Pin DDR2 FB-DIMM Dual Channel Kit Server Memory

BFG Tech GeForce 9800 GX2 BFGE981024GX2E Video Card

Antec TITAN650 Black Server Case

HD: 500 (SATA)

OS: Vista Business 64-bit

The only problem I have is not sure what type of fan/heatsink I should get for Opteron cpus...!
I'm looking for something quiet, I'm going to use this system to play games,rendering and programming

Also if you think I could improve things in this list let me know

I would stray away from AMD. If you want dual CPUs go with Skulltrail.

Considering the fact that I have to buy two QX9775 cpu for that motherboard... thats going to be more expensive then the system I have listed above.

here is what I mean, the cheapest price I found for a Intel Core 2 Extreme QX6850 is around $1,119.00 and a QX97750 costs around ~$1,694.00 ... so I would assume QX9775 would be around ~$1,900.00 ...!

well the system I have listed (in my first post), costs around ~$1900 (US), from newegg;
Unfortunately newegg doesn't ship to Canada !
