building custom pc for gaming?

Hey all,

Budget would be around 500-600 (more like guidelines.. so no need to oversweat about it, but would be great to not exceed it)

For now I have put in my basket intel core i5 4460 3.2ghz .. around 190 eur. and graphics card MSI GF GTX960 2GB - for 205 eur .. (already 400eur.. so looks not so promising to stay in 600eur margin, but could be possible to try ?)

Maybe i`m going over the board with these two ? In computers i`m not really that smart.. So any suggestions would be appreciated

I looked that gtx960 would be good performer with games, so I was interested in staying with that.. But how about the processor .. is the intel i5 that good to pay more then for AMD processors ?

And about the motherboard - Can a 100-150 eur motherboard be good performer with that i5 and gtx960 ? if yes, which one would you prefare?

When looking at full price after all the components it`s going towards 700 already, and i`m not quit sure if i`m willing to pay that much .. Any cheaper alternatives that don`t secrifice performance that much ?

I would be happy if I could run gta 5 decently (of course to run it great would be awesome) but i`m being modest.. At least when I checked it at - http://www.game-debate.com/games/index.php?g_id=13... - with this processor and graphics card it said it would run on high ..

As a noob in all this I would appreceate any help :D thanks ;)
