Hi guys, i know that you have noob questions like this every day, but please i ask you to take a few moments of your life to help me ;) 

>So, i want this GPU - GTX 770 (PCI Express x16 3.0)

>My motherboard supports pcie 3 x16 so no problem !

>My CPU (i5-2400) apparently it does not support PCIe 3.0 x16, it only supports PCIe 2.0.

>My two questions are: 1. Do i need to change CPU because it is not compatible? 2. Does my CPU supports the GTX 770 or a GTX 760 would be a better option?

Thank you in advance !

The performance difference between PCI-E 2 and 3 is very minimal, so little as you will not notice a difference. I think your CPU will work fine with the 770, although if you have the cash I would suggest upgrading the CPU and motherboard because it is quite old.

i am not 100 percent sure but i think that it could handle it as 3.0 is a matter of a few percent gain in coding efficiency.

i think that you would be better off with a cpu upgrade for the 770.

what motherboard do you have?

I have this one Asrock Fatal1ty Z77 Performance (http://www.asrock.com/mb/Intel/Fatal1ty%20Z77%20Perform...)

Another question, my motherboard supports up to 2800Mhz DDR3 RAM, but my cpu says that only supports up to 1333... So i can only have 1333Mhz?

I'll explain you my problem :D 

I have a crappy motherboard, a crap PSU, a i5-2400 and a GTX 550 TI. And i want to upgrade it ASAP to run latest games at 1080p, like GTA V and incoming games. The thing is that to make a new PC from scratch, that it's worth it, i need arround 650/750 euros. So a friend told me that i could upgrade my MB, my GPU and my PSU for arround 450 and it will run really nice for the investment

Yes the CPU would limit you to 1333Mhz

Intel Core i5-3570K 230$ http://www.newegg.com/global/uk/Product/Product.aspx?It...
Intel Core i5-3570 210$ http://www.newegg.com/global/uk/Product/Product.aspx?It...

these 2 cpu's would be the best match for the gpu and current mobo. K models can be overclocked but i would not recommend to do so on a motherboard that is showing its age.

1333mhz is a little under powered but you could most likely run the sticks you have now at 1600mhz with a timing adjustment. high speed ram mostly benefits discrete graphics and various other tasking but most users are fine with 1600mhz.
for the price of the cpu's and the age of your mobo considered along with the class of your 770 you may want to consider...
z97/z87 mobo or for no overclock you can get a cheaper lga socket 1150 mobo that would support one of the latest i5's
