Building your own music pc????

[ampassasinbirmingham]

CPU--- Core 2 Quad Pro Q6600 "Energy Efficient 95W Edition" 2.40GHz
Ram--- 2GB (2x1GB) PC6400C4 800MHz Ultra Low Latency DDR2 Dual Channel Kit
Motherboard--- Gigabyte GA_P35_DS3R (Socket 775) PCI-Express DDR2 Motherboard
Hdd--- Samsung SpinPoint T HD501LJ 500GB SATA-II 16MB Cache - OEM
Graphics--- Graphics:Asus ATI Radeon EAH2400 Pro HTP Silent 256MB DDR2 HDTV/DVI (PCI-Express)
Screen/s--- 2 x 22" acer monitors
Case--- coolmaster i-tower 930


Ok so maybe i should look at getting the above??
Is that a pretty decent processor? Should I get more ram, will this run music apps very sufficiently? Do I need to buy anything else, fan etc? Will that graphics card run 2 monitors? Im getting a friend to build it so I don’t have to worry about that. Would you be happy with this system? I take it running a cracked OS is very risky? How could this system be made better?

Thanks in advance guys!!!:)
