My current system is lagging behind a bit and I have decided its time for an upgrade. I like the look of the new Intel Core i5's as they suit my price bracket and what I use my system for but past that i have no idea what to buy as it was a long time since I put any PC bits together. I would need a CPU, Mobo, RAM and a power supply as I don't think my old 400W FSB one will cut it. At the moment I need onboard RAID capability and would like 2 PCI-E 16x slot in case I want to move to 2 GPU's in the future (probably ATI/Crossfire). I think 4Gb of RAM would be good but i'm not sure. Any recommendations would be great! Thanks very much
