Hello Everyone,I'm new to avsim and was wondering if anyone who runs GEX, REX, FTX, and UTX could tell me what the combined memory usage was for all those add-ons combined with FSX? Just trying to figure out if my 4GB (2X2gb) of DDR2-800 will be enough or if I need to throw another pair of 2gb sticks in (to make 8gb total) to handle everything. I would also like to know if anyone would take a look at my system specs below and tell me if I have the horsepower in all the other parts of my rig to run all these add-ons smoothly.My system specs are:AMD Phenom II 955 OC'd to 3.4 ghzAsus m4a785T moboXFX Radeon HD 6790 1GB GPU OC'd to 875mhz/1100mhz4gb g.skill ddr2-800 RAM (pc2-6400) 5-5-5-18WD Caviar Black 500GB HDWD Caviar Blue 320GB (Storage)Apevia 700W PSUIt's worth mentioning that I run 3 22 inch monitors (acer p215H) in Eyefinity mode (3x1600x900 resolution - total res 4800x900)Looking to get a framerate of 25-28 while running all these add-ons. Still have room to overclock further on both CPU and GPU if needed. Thanks!

Sorry, I forgot to mention that I'm running Windows 7 64 bit for my OS.

Hi,I am not familiar with your AMD processor. I am running a qx9650 with 4gig ram and a gtx285 1gig video card. I am oc'd to 3.7 and in Seattle I can run Xtremely Dense complexity and very dense autogen with a upper medium complexity a/c i.e. I fly mostly Carenado but love the L-39 and the new Milviz Talon and the Duke. I have MyTraffic X @ 30% airline and 50% GA traffic and feeds from ASE, radar contact and IYP from another box. I am running a comfortable 25-28 FPS and fairly smooth in the Seattle area. GEX and UTX really will not stress the box too much but there is a hit of course between the stock scenery. As you may already know, FSX is very much CPU dependent. Even folks who have extremely high end processors and the rest to go with it, still have issues. Personally I dont think you can go wrong with UTX GEX as it really is one of the first scenery addons everyone should invest in. I also run the orbx scenery but I really have to crank down the detail in order to get the smoothness I am comfortable with. It is all a tradeoff as you will soon see. Hope this helps.EDIT: I am running Win 7 64 also. 4 gig should be fineBob

Hmmm... the PC will do pretty well with FSX. You'll notice a loss of performance mainly in clouds. ATI cards do poorly compared to nvidia cards in clouds - apparently it has to with ATI not fixing their drivers for (dated) FSX.RE the RAM... 4 should be fine. 8 wouldn't hurt though.

Thanks for the insight guys, just wanted to make sure my rig could handle all these add-ons @ 25-30fps before I spent the $$ on them. Sounds like I should, in theory, be able to pull it off.

AMD Phenom II 955 is a Quad Core CPU so should be up to the job.It's one of AMD's better quad core CPUs.

Cool. Thanks to all for their input.
