1. Are really gonna get that Multi-SLI board?
How many GPUs are you really planning to plug into it? Only 2? than what is theuse of having multi-SLI? if you are gonna use only 2 GPUs?
2. 4GB RAM/Slot? Then you will need at least 3 of them (remember the 3 channels) for 1366 mobo, which mean 12GB RAM in total. Do you really need that much? Gaming rig doesn't need that much, 3x2GB should be enough.
Note : For Intel 1156 and AMD mobo you will need 2x4GB or 2x2 GBRAM (2 channels)
, 4GB is enough for gaming.
3. Raptors? Forget them! Get an SSD for your master partition and a normal big capacity HDD for your data.
