Hello all,
i am new to the community, and i am quite surprised that everything i googled about my new "upcoming" pc would lead me here ^^

Epic site, keep it up !!

So, i am about to buy a new gaming-oriented pc, and i am about to give a budget of 750 euros Max.
After a little search i ve found a very good mix up, but i want your opinions too.
So far this is the build up :

Intel Core i5 4570 (1150/3.2GHz/6MB) - 189,90
Sapphire 7870 2GB OC - 184,91
Turbo-X 550W Value Series II - 45,01
Samsung DVD-RW SH-224DB/BEBE Black Bulk - 19,90
Samsung 120Gb Sata III 840 EVO - 74,89
Corsair Carbide 300R Gaming case (Midi Tower,Black) - 71,91
Crucial DDR3 8GB (2x4)kit 1600MHz Ballistix - 102,90
Gigabyte MB H81M-D2V (1150/H81/DDR3) - 59,90

Total of 749,32 euros

Now, i am new to pc-building so i have a few questions i hope you can answer.
These are :

1)Do i need more power than 550w?

2)Do i really need 1600 mhz memory? After some research i found out that 2x4gb memories are better than 1x8gb, but i also found out that to achieve 1600mhz you must change something to Bios. I also read that 1600mhz memory are used for OC cpu's, like amd, so do i really need 1600mhz for memory? I would like to save some money and go around 700euros, if 1600mhz memory isnt needed.

3)Do you consider Raid ordinance a must? I' m sure i ll soon need more memory, 120gb is nothing, so i could take a motherboard a little more expensive, with raid ordinance, for better speeds.

Also if you want to sugest me something, or you find something wrong, please let me know!
Thank you for your time, i appreciate it :)
 
with a gaming pc use a 650w cosair or sesonic or a first level power supply. ssd are for people that want fast boot times..if your build funds are limited use a reg 1tb hard drive then add the ssd latter if needed. the power supply..cpu and gpu are where the funds should go to.
