I have an E6600 @ 3.6 on a Striker Extreme with 4GB pc6400 undercloced to 667mhz, FSX on a dedicated 7200 rpm HDD.

I have about $100 to kick down for an upgrade and I was wondering if my money would be better spent on a decent solid state drive just for FSX or would I be better served with better ram.  I would like some memory that is faster and 2x2GB rather than the 4x1 stick I use.  I have everything tweaked out as per Nick's instructions and get very good results from running my system as clean as possible but I just got a new monitor (Samsung HDTV 37" ) and would like to be able to push the traffic sliders up a bit while still getting a smooth flight in turns.

Either way, I will be getting both of these upgrades as well as a Q9550 in the next couple of months but I'd like to get the most bang for my buck asap.  

Also, is there a noticeable advantage of running two SSDs, one with FSX ~30GB and one with the OS?  I'm just guessing the drive will better boost the sim as it reads scenery files in flight but I'm not very knowledgeable as to the extent that FSX reads and writes the OS drive while in use.

Thanks for any help or suggestion and I've been a long time listener, 1st time caller.  This forum is priceless.


*edit*  I just read in another forum where NickN talks about the fact that CPU cycles are freed up by SSDs rather than perf gains by the drive itself as scenery is loaded into PM.... 

But the question still stands:  SSD or RAM?
