Help with Memory Selection for New Build

[spartancal]

I will purchase a Intel E6600 processor. I have narrowed my motherboard choices down to the following:


1. Foxconn 975X7AB-8EKRS2H - Has everything I need including eSATA if I decide I don't need SLI (one 8800 GTS may be enough for me. I like games but I'm not a hardcore games) and its relatively cheap.


2. Asus Striker Extreme 680i board (I want to learn to overclock - this board makes it easy for beginner and IF I find that I need SLI and buy a 2nd evga 8800 GTS down the road for SLI)


I plan toi install 4 GB of memory (for photo editing with photoshop) will that be a problem to OC?

Will the memory on the video card 8800 GTS reduce the amount of memory my applications can address?

Can the motherboards listed above run with PC2-8000 memory G.Skill F2-8000PHU2-2GBHZ 4.0-4-4-5 @ 2.2 ~ 2.4V?

Finally can someone explain the DDR2 reference and the PC reference are related? For example DDR-800 is the same PC-6400.

you really don't need RAM faster than DDR2-800(PC6400) CL5. With such RAM you'll be able to OC your CPU, more than 50% if it can. Any other faster RAM(DDR2-1000) will boost the performance marginally, less than 5% in the best case. But the price difference between the DDR2-1000 CL4 and the DDR2-800 CL5 is huge. You better invest the money difference in other components.
