Welcome.
1) Those Pro Combat Pedals look nice. I have heard great things about them. I have CH Rudder Pedals. They work great for over 7 years but they are pretty close together, and it doesn't take much to push them. The Saitek Pro Combats have a dial on them where you can adjust resistance.
2) I went from a TrackIR 3 to a 5 and it was worth the upgrade. The camera has a wider view so it doesn't lose the dots as easily. I bought the track clip too. I don't think it's worth it looking back, unless you really have a problem with wearing a hat. It's pretty cheaply made, feels like it's going to break and mine already did sort of. Plus there's another wire to worry about so I have 2 wires connected to my head with headphones and the track clip.
3) I don't think you need a SLI setup to enjoy this game cranked up. I run an ATI 5850 1GB and it works great. If getting a new card I would get 1 card that has at least 2GB of ram on it thought most say that helps.
4) Not gonna lie this sim's interface is awful. They didn't spend much time on it, it's nothing like the old sims from the 90's. Those features do sound cool though.
5) No weather in the current sim really except a few clouds. I guess the add on they are working on now (Battle of Moscow) will include more weather options, as well as possibly a Yak fighter or some lend lease US or British aircraft. It's an earlier war scenario though so I don't think any late war planes will be in this up coming add on.
Hope that helps there's many more people here that know more than me. Enjoy this sim! Try flying online it's a blast on the ATAG server
