I already have 8 GB memory (4GB x 2) , but they are 800 MHz. Does it help to get higher bandwidth memory like 1866 MHz or 2400MHz?
I also have SSD, but using it as a boot drive, so while booting is fast, the pics processing takes longer as it has to access the data from the HDD. I may buy a SSD 240 GB, I was think if a PCI-E SSD will help?
I was thinking if an overhaul of the system will be better. Like changing to a new LGA 1155 motherboard (that supports my core i7 3770K) what do you think ? any suggestions for a new motherboard or I should not?
1) DDR stands for double data rate. RAM that is reported as 800MHz is sold as double that - 1600MHz. Going faster than that will be a waste of money and get you very little return.
2) Consider buying a second SSD, or else just make a partition on your current SSD to use as your workspace - either would work just fine. No, a pcie SSD shouldn't be bothered with - it's a LOT more money for not much benefit.
3) ...you HAVE an LGA 1155 motherboard. Why would you buy a new one? Better yet, you have a z77 chipset, which means you can buy a cooler like the Hyper 212 EVO, install it, and overclock your CPU to get faster speeds.
If you do that, make SURE that you read a LOT about how to do it, because if you just let software or auto-voltage on the motherboard do it, it'll over-volt, and cause way too much heat, possibly damaging components. Do it right, and do it by hand.
You really have a very good computer there; for what you're doing with it, there isn't much upgrading you should do to it before the huge upgrade of jumping to workstation parts.
