Is the R9 290 overclocked better than the GTX 780 overclocked?
Also, are SunFlower and TeamGroup good brands?

The i7 isn't better for gaming than the i5 so I'm lead to believe? If I changed i7 to i5 that saves me £70.00. Could that £70.00 improve any thing else?
I think I prefer GTX 780 over R9 290. Is that motherboard/cooler better than the others listed?
Thanks.
