Need help with my first build

I already have 1 in mind with my 1200 dollar budget but then I asked somebody and they made me make unsure about it (even though they didn´t help with it :P)

My initial concern is that the RAM or the Video card might not be compatible with the Motherboard. I´d like the budget to go to 2000 even though I unfortunately surpassed it by 30 dollars. I assume there are cheaper motherboards out there but I have little knowledge about which are good and which are mediocre.

Your processor could be better for your budget. Knock some off on your keyboard and get a better CPU

Any recommendations? At this point I´m only concerned about the compatibility of the 560ti and my motherboard.

Hmm...what are you planning on using this build for?

Playing games like BF3, Skyrim, etc.

Right okay then. Go with the i5 3570k which you can overclock like a monkey on bananas. The 1155 socket will fit your motherboard and stop any bottlenecking. Your GPU choice is good.

Oh, they are exactly the same price lol. Didn´t realize it. Can you give me a word on the compatibility of everything?

It all works together mate.

Ok thanks a lot
