Choosing the hardware which can proceed up to 10g speed

[Naim Shafiev]

Hello.
I am looking for x86-64 based  hardware , which can proceed up to near 
10 gigabit speed in my tasks.
My tasks are:
0. Can minimal proceed around 600 kpps . The packet average size is 
around 600
1. Can be applicable in caching tasks(like caching youtube)
2. Can do a Level 7 parsing( to run snort , finding some text , and etc)

Also i want to use the netmap framework with libpcap .
I am sorry if there don't discussing the network perfomance and hardware 
choosing topics, but i cannot find more good place except this.
