| what do dual and tripple channel ram motherboards mean? |
In simple words, it's the nº of channels the CPU use to "talk" with your RAM. More channels = better speeds but also more latency. More: wikipedia
Most CPUs use dual channel, the "old" Intel's i7 (the likes of 920/930, 950 etc.) use triple channel while the new i7 (3930K) go with quad channel. When buying the RAM the difference is that dual channel kits comes in packs of 2 modules, triple channel comes in packs of 3 and quads in packs of 4.
| the same for pci-e slots,what do channels mean |
The combo CPU-chipset (like those of X79, Z68, P67, 990FX, etc) talk to the devices that you install in the motherboard via a series of lanes. This number of lanes are finite (X79 gives you 40 PCIe 2.0 lanes while the 990FX has 42) and are spreaded into the different PCI slots that comes with your mobo. Simply put, the more the better. But be careful with the names, a PCIe 2.0 is different from a PCIe. To learn more: wikipedia
| and speed mean liek 16x or 8x? |
This multiplier tells you the number of lanes the PCIe uses (16x = 16 lanes, 4x = 4 lanes). Every motherboard has at least 1 PCIe 2.0 x16, and this is where the graphics card goes. If you go with SLI/Xfire you must look at the other PCIe slots. When using 2 Gfx cards some boards will split those 16 lanes into the 2 cards (8 for each one). The difference in performance is usually negligible. See more examples here: http://www.hardocp.com/article/2010/08/23/gtx_480_sli_pcie_bandwidth_perf_x16x16_vs_x8x8/
I hope it helps.

1-does the 2nd PS-E slot not being 16x reduce the speed and performance
or does it only need 16x in total,8x in one and 8x in other
2-there should be enough PCI-E slot to accomodate audio card,wifi,bluetooth card
3-about ram lanes,is it necessary to ram in specific amount or is it just to increase performance?
for example:if i buy 8gbs of ram and cpu support triple channel.and suppose 8gbs are divided into 4 2gb memory.will the 4th memory not work or perform as well?

1-Most, if not all, motherboards come with 2 or more PCIe x16 slots. If you only use 1 Gfx card it will use the 16 lanes available but if you use 2 Gfx cards then the number will be split into the 2 slots making 8 lanes for each slot, but that depends of the chipset. Intel's z68 (s1155-2600K) can only give 16 lanes for graphics (1x16 or 2x8) but the new X79 (s2011-3960X) has enough to give you 2x16 + 1x8.
But remember that, as the article I linked says: "It seems that at 2560x1600, even with 4X AA, there was absolutely no difference between x16/x16 and x8/x8. This is good news if you game at x8/x8 on a single display configuration at 2560x1600 and below. You simply are not missing anything, and moving up to x16/x8 or x16/x16 will yield no performance improvements or gameplay differences".
2-Don't worry for that, you can use all the slots of your mobo at the same time without problems as, other than the Gfx cards, the rest don't need that much bandwidth.
1 and 2- See the specifications and the pics of this mobos:
Intel Z68 - http://www.asus.com/Motherboards/Intel_Socket_1155/P8Z68_DELUXE/#specifications
2 x PCIe 2.0 x16 (x16 or dual x8) If you only use the blue one you'll have 16. If you also use the white one both will have 8.
1 x PCIe 2.0 x16 (x4 mode, black)
2 x PCIe 2.0 x1
2 x PCI |
Intel X79 - http://www.asus.com/Motherboards/Intel_Socket_2011/P9X79/#specifications
2 x PCIe 3.0/2.0 x16 (dual x16) *1 The 2 blue slots will give you 16.
1 x PCIe 3.0/2.0 x16 (x8 mode) *1
2 x PCIe 2.0 x1
1 x PCI |
3-I'm going to be honest: I don't know.
