Get some more or get some new?

[Laser man]

I have 4 gigs of Kingston HyperX ( 9-9-9-27 ) 1.65v and with Sandybridge calling for 1.5v and lower latency making it easier to overclock, I was wondering whether I should get 4 more gigs of Kingston or get 4 gigs of better RAM, maybe even 8?
Which would be best and why??? I do a bit of GIMP, but not loads, browse the internet and game

I wouldnt bother tbh, your current RAM should be OK, Im sure youll still be able to OC it well, OcUKs own bundles dont exactly use high end RAM
