Lion 4GB vs 8GB Ram?

[lhayati]

Hey,

Would an upgrade to 8gb be beneficial for an iMac 21.5"? Would I see any speed improvements?

Also where is the best place to buy ram (2x 2GB) in the UK.

I've seen it for £29.99 in crucial: http://www.crucial.com/uk/store/mpartspecs.aspx?mtbpoid=8CFE9228A5CA7304

What Apps do you run? I am using 4GB of RAM right now and my most power hungry apps right now are either Team Fortress 2 and Left 4 Dead. With these open I still have around 800MB to 1GB of RAM left.

Does Activity Monitor report a large number of Page Outs over a relatively short period of time? Do you see a significant amount of Swap used? If so, then yes, you should see a speed increase. Otherwise: No, not really.
