Secondary Rig being built, I fancy a change..

I am building a second PC for FSX. I am going to get wideview and network them together, using one PC for outside views and instruments, the other for cockpit view. By the way I would be interested to hear of people's experiences using wideview, it seems a good way to solve performance issues in FSX if you dont mind shelling out for 2 PC's !!I have ordered this memory: Mushkin Ascent 998692 6GB (3x2GB) XP3-12800 Ascent REDLINE 6-7-6-18 DDR3 Memory Module. I have been reading various posts and this seems to be recommended, have I ordered the right stuff? I hope so!!I had planned to go i7, use the 920 DO stepping and overclock to as near 4GHz as I can. While I was looking at hard drive options ( I am going to go for 60GB OCZ vertex drive for the OS) I came across some SAS drives. I have found this:http://uk.asus.com/product.aspx?P_ID=W8KQx...&templete=2 motherboard, that has 2 SAS ports. Will this board still offer the overclocking potential of the P6TV2 deluxe? It seems pretty similar. Is it worth going for the SAS option ? The drive I was looking at was the same price approx as an SSD of half the capacity. And will my overclocked 920 perform as well as a 965 or 975, would I notice the difference if I shelled out the extra
