thanks all for the replys. and sorry i should have been more clear it will have 4gb of Corsair 2GB DDR3 XMS3 i was using the above as a reference. and thanks for the advice about the psu, just read a few reviews and have decided to go with the PC Power & Cooling Silencer 750 Quad-SLi PCI-E 750W. as for the screen i will be using a Samsung SM-226BW 22

i will be overclocking so if you have some advice on cooling it would be a help, mite have to wait a few weeks though as im very near my cash limit

BTW will this be a gamming rig or multitasking ? also what size monitor you gonna be using

i will be using it for mainly gaming and video editing
