hi guys,

i was a power macuser for about a decade, but I miss the assembling of my own computer and ... I don't want to spend too much bucks on a machine

so this is my setup i am going to buy. what do you think? should work well?

gfx: Sapphire HD4870 Vapor-X 1024mb
cpu: core i5 -750
mobo: GIGABYTE P55-UD4
memory: Kingston ValueRAM DIMM 4 GB DDR3-1333 Kit <-- I am not sure if it is necessary to get faster rams? like 2000mhz ?

optical: LG GH-22NS sata

thx
