I have had XPX for a little while now( around 4months) and I used FSX a couple times in that duration and lately I have actually uninstalled my fsx, XPX is whole alot better and you will say the same soon, some planes you may want to look at are the 777, CRJ and the A320neo, they are fabulous. And i basiclly have a FX 8350 and a HD 7870 and i play XPX max out @ 1920x1080, even when taking off and landing at some more of the advanced airports I still have a fluent experience..
